Design is a funny thing. The word itself carries a certain weight, it is somehow deliberate and exciting at the same time. Yet, so often design is let down by the poor translation or communication of ideas. You may have an excellent ‘design’ in your mind, but displaying or presenting that to a client is an entirely different matter. Every designer faces the same challenge of communicating their design ideas in a thoroughly engaging way: whether the communication be to their clients, other stakeholders or even as part of their own internal design process.

This is a site about Revit, but this article is about discovering new possibilities, new ways to express your design, new ways to add context, realism and reality. It is also about a powerful piece of software called Lumion a design communication tool that I personally use and have used for quite a few years. Thecombination of Revit and Lumion give architects a complete toolkit for modeling, understanding, sharing, adjusting and presenting their design.

So, what is Lumion? Recently, I was speaking to the Chief Operating Officer of Act3D, (the parent company of Lumion), Roger Hammond. He told a me a very heartening story about the development of this piece of software…

Often we don’t immediately recognise the full potential of a new, beautiful idea. Roger describes that Lumion was initially designed to be a powerful presentation tool, but Architects soon discovered that it can also shift the way they design in very positive ways. He describes how a new user of Lumion can easily get comfortable with the basic concepts of the software, even those who are not ‘technical’ or especially comfortable with computers. Yet, once they start using Lumion, they get to grips with it easily and quickly learn to iterate design changes and brief clients more rapidly and smoothly. Lumion gives a certain realism and context to your design that can assist you to modify and improve the design internally, before it is even time to present it to anyone.

We often become so used to a way of working that we almost feel like there is no other way, or that perhaps we already have the best way. Yet, if that were true, innovation would not be a reality. Sometime, disruption is necessary. So if you have an established way of designing and communicating, take this opportunity to reevaluate as I review Lumion.

The user interface itself is nice and clean and easy to read and understand. As someone used to complicated programs like Revit and AutoCAD, this is a welcome breath of fresh air to me. Rather than present you with an overwhelming and detailed set of buttons, Lumion allows you to progress your digital presentation in stages, from Building to Materials and Lighting and Presenting and so on.

Lumion – A User Interface For Designers

In this way, the development of your design and your presentation output can be very logical and layered. You can import your design from a variety of different programs and platforms (like Sketchup and ArchiCAD, not just Revit), and once imported you can add people, trees, and soft and hard landscaping. You can sculpt the site topography and add water and grass areas. Once you feelcomfortable, you can dig deeper, modify lighting, adjust materials, add special effects, work on camera angles…

And finally, you can display your design in some truly simple yet beautiful and intuitive ways. The key thing is not to be afraid. You can’t break things in Lumion, it is not a imposing or complicated environment. Navigation is straightforward, nothing is very complicated. As you use it, extra functionality will reveal itself. It is a tool that has been built for designers, and its development has been shaped by their feedback. Roger recalls that it is not uncommon for users to say that Lumion has changed my business”, and there are plenty of ‘wow’ moments. For example you can add the ocean to your scene with just one click…

We have experienced this realisation at Virtual Built. Recently, we have been demonstrating Virtual Reality tools to our clients. However, in some programs it can be difficult to populate a scene quickly and then output to a suitable VR platform. This is not the case in Lumion, as the included content means you can get upandrunning quickly. If you have a few basic building models, you can add site context and a few nice little details like a truck or a crane to create a site utilisation model, and then output to a number of different VR panoramic formats.

I have been using Lumion over a number of years and different versions, so I was excited to see theupdates and new features available in Lumion 7. The major new features are listed below, and we will dig into each feature and uncover the new opportunities they present.

Lumion 7 New Features
OpenStreetMap (OSM) is an online resource that stores 3D building models along with map information like roads and water areas. In the past, I have used many methods to try to get a locality plan or model created, and it can be quite clunky and challenging. However, in Lumion 7, this is now completely automated. Using the OpenStreetMap import, in just a few minutes you can have a realistic map in Lumion to locate your building models, and it will even have adjacent 3D building models as well! It will automatically ‘cut out’ your own building model from the OSM data. The OSM function in Lumion 7 is still Beta functionality, but it can already be very useful to quickly add context or a background to your design.

To get started with OSM in Lumion, just:

  1. Start Landscape mode (left side flyout menu) and turn the OSM switch ‘On’

    OpenStreetMap Switch
  2. Click the Longitude / Latitude area to bring up a searchable map
  3. Search for your location

    Location Search
  4. Set the import Range and press Download

Tip: hold Shift + Spacebar and use arrow keys to move quickly on large sites

Check out this page for more information on OpenStreetMap and Lumion.

New Features for Weathering and Foliage
Building models sometimes appear ‘flat’ due to the way various platforms handle materials. However, in Lumion 7 you can now remove the coldness of computergenerated imagery by seeking out edges, roughness and other properties of natural materials to make them look like they’ve been around a while. My associate here at Virtual Built, Michael Clothier, recently used this to add realism to an important theatre building in Adelaide that is currently under construction.

You can also cover models with leaves or add weathering, ageing and transparency. Even transform any object into thousands of leaves or add ivy to a wall… These tools are implemented through the Material Editor, so the workflow is logical but the effect is quite impressive indeed.

Here are some examples:

Boardroom

 

 
Pool Villa

To get started with these tools:

  1. Enter the Material editor
  2. Select a object to change
  3. Set a Material from the Lumion Library, and doubleclick on it
  4. In the editing pane, you will find the tools on the right…

    foliage_weathering.png

  5. Then, simply drag the sliders until you have the desired look and feel


Light strips

Sometimes, the available Lighting tools in presentation software can be quite limiting. Happily, in Lumion7 you can now add light strips or area lighting, meaning you can go beyond simply ‘spot lights’. I really enjoy adding these new lights, because as usual they can be edited with sliders, and you can view theeffect in realtime… there is no need to wait for a lengthy rendering and then realise the lights were switched off 🙂

To get started with the new Light types, open the Object pane:

lights.png

Then select the Area Lights tab:

line%2Blight.png

Place the light and then modify the sliders until you have the desired effect:

MyLumion
You can use Lumion to share a navigable panorama to anyone who owns a smartphone. It is incredibly simple and powerful and is one of the features I hinted at earlier in the article. It is something that allows you to put your design on display in a new way, and get valuable client feedback and engagement. Then, you can quickly iterate the design and send them a new link.

We have used this to create sets of views for various stakeholders, but the key thing is really how easy and quick it is. You don’t have to print something or even save an image and find it on your hard disk. You can do all of this creation and sharing in just a few clicks. We have found it to be a real gamechanger.

You can view a basic demo of the technology from one of my sandbox projects here.

Summary
There is no software program available that can automatically interpret a client’s design brief, provide suitable visualisations, interpret client feedback, and iterate this process while learning at each step. A good Designer can do this. But with the right tools, parts of that process become much easier. As a designer, you will be able to interpret the brief and interpret client feedback. With Lumion, you can quickly and easily present your design, in context, and in a multitude of rich, realistic, immersive ways. By thus improving the way you communicate and iterate your designs, you designs themselves will improve. And your client satisfaction level will soar…

So I recommend that you give Lumion a try. And be ready to be surprised 🙂

Guide 1: Using Lumion in Virtual Reality Workflows
Lumion VR
Lumion VR viewer is no longer supported, instead you can render static images for viewing on a variety of VR platforms. I will provide some notes on how you can do this below.

vr-settings.png

Using A Mobile App like PlainVR
Here’s how:

  1. Render VR Panorama images (these will be 360 degree jpg files). You can use default 64mm eye to eye and 360 slices
  2. Upload those to a photo sharing service
  3. Get the direct HTTP image link
  4. Copy and paste that into the QR generator at http://vr.plainconcepts.com/ and click “Generate”
  5. Install PlainVR app on your phone or tablet
  6. Scan the QR code from the app

Embedding VR to a Website with VR View
Google has kindly provided a web service for rendering images in VR, its called VR View. After creating your stereoscopic image, you can follow these steps to embed it into your site:

  1. Upload to a photosharing site (like imgur)
  2. Input code like this to your site:
    vrviewcode.png
  3. Publish and view on web browser or mobile device

Here is an example for you to look at…

http://wrw.is/p/vr-view.html

Note: in Blogger, after you add an ampersand character to the code, it converts it to some other characters. basically, you can’t ‘edit’ after you input the code, if you publish it directly it won’t replace to & and it works…

Using Oculus with Lumion
To do this:

  1. Render a 360 jpg file from Lumion then
  2. View it in a panorama viewing app, such as Oculus Photos
 

How To View On Oculus Rift on Vimeo

Note: You can use a Oculus DK2 with an Xbox controller instead of an Oculus Remote. Typically use theA button to select what you are looking at.

Guide 2: Layers
Did you know you can easily move objects between layers?

  1. Activate Select mode
  2. Select Objects
  3. Activate the Target Layer
  4. Hover on the layer
  5. Use the up arrow that appears

I love unique tools. In the BIM world, we are presented with a wide array of visualization software, each supposedly better than the last. But I am interested in something that has real power, that is truly unique, something that can give me and my work an edge over the competition. And Lumion is one of those unique, powerful tools.

It is fast, easy to use, and the visuals are so immediately pleasing. In just a few minutes, you can go from a Revit model with links and topography, into a beautiful 3D environment. There is a huge library of People, Trees and Vehicles included with Lumion that can be placed immediately into the scene. The more time you spend working up the scene, the better and more realistic it looks.

During the preparation of this article, Lumion 6.3 was released. I have made an effort to discuss key points from that new release here. The big new feature of 6.3 is that Lumion now supports Samsung Gear VR and Oculus Rift! Find out more at this link.

vrLumion.png

So that’s the quick summary, but how does Lumion integrate with a real Revit environment? What considerations are there when working on federated models? What tips and tricks did I discover along the way?  Read on to find out…

This review is divided into the following major sections:

  • Real World Use
  • Summary of New Features
  • Basic Use
  • Specific Tips and Workflows
  • Learn More

Real World Use
If you want a quick overview of what can be achieved, check out this Showcase page on the Lumion website.

Test System
Lumion uses a live rendering engine, so effects and animations all essentially occur in real time. This means that you need a decent computer, with a good graphics card, if you want to get the most out of Lumion. I tested Lumion on my 2 year old workstation, with these specs:

  • Intel Core i7-4930K (6 cores, 12 HyperThreaded) CPU
  • 64gb RAM
  • NVIDIA Quadro K4000, 3gb GDDR5, driver 353.62
  • Samsung SSD 840 EVO 500GB + 3tb secondary drive

The above specs were more than acceptable for my use, but you may find that a newer gaming graphics card would compensate for a current mid-range system with less RAM.

From Revit
Lumion imports a number of native 3D formats, including FBX and DWG. However, there is also a Revit export addin (called the Revit to Lumion Bridge) available that gives better optimization to the exported 3D data. I found the addin very quick to use, even on a large site with multiple buildings. After exporting into one container DAE file, you then use the Import option in Lumion to bring that model into the current Scene.

EXPORTtoLumion.png

If you have some well developed Topography in Revit already, you probably just want to ‘feather’ the edges of the Lumion Terrain. A Lumion scene is made up of a number of parts, but it always has a base Lumion land surface (that could be flat or modelled to really any land form), and then you typically have a model imported from some other software, following which you would usually add content and entourage to the scene, such as People, Trees and Vehicles.

After you have imported a model and integrated into it into the scene, I feel that it is very rewarding to add some content to the scene immediately. The large library of content allows you to quickly get a ‘look and feel’ happening that will help drive the artistic process from this point forward.

I say “artistic process”, because that is actually how Lumion makes me feel – like an artist, not like a boring BIM technician. And that is a good thing! Rather than wrestling with the usual mind-draining, complicated Revit modelling tasks, Lumion is like a breath of fresh air. The payoff is immediate, unlike some other rendering workflows that often require many hours of material mapping before anything remotely aesthetic can be generated.

From Navisworks via FBX
I thought it might be interesting to try and play with a relatively basic building form or mass, and see how Lumion can make even basic geometry look quite impressive. To start with, I used a model in Navisworks of Room spaces (which were exported from Revit via NWC). Then I exported these Room masses from Navisworks to FBX.

FORMS.png

The resulting FBX file was 167mb.

I opted to try the Mountains in Spring scene template. The water in Lumion is nothing short of beautiful. Its almost too good to try and demonstrate with a screen capture, but I’m going to try anyway… Keep in mind that as you navigate in Lumion, the water is moving and rippling and lapping away at the smooth stones. Amazing!

water.png

In just a few minutes, I had trees, a power boat, a sunbaking man, and even a fish, horse, and offshore wind turnbine placed in the scene. Lumion has this potential for rapid, beautiful scene development that is unparalleled in my experience.

quickscene.png

Modifying Placed Objects
The Lumion interface is clean and uncluttered. Sometimes, you will ‘discover’ how something works in Lumion, and it will just make sense. For example, if you are trying to move a Person and can’t select them, keep in mind that you should pick the object Category from the bottom-left corner of the window, and then you will be able to modify objects of that Category.

ObjectType.png

Modifying the Environment
I was impressed with the fact that the sun height is extremely easy to modify, to get things looking just right, as the screencast below shows:

Key points to remember
Some of the features added in Lumion 6.0.1 and 6.3 are focused a lot on improving the image quality, which means you are getting the very best output from the scene creation work that you undertake. Another key differentiating feature of Lumion is the overall ease-of-use. It does not feel like a complicated piece of software, and it allows you to get up and running quickly. Then, as you learn more about Lumion, you can progressively discover the additional features that are just below the surface of the main user interface.

Summary of New Features
Lumion 6.3 now supports the rendering of VR panoramas for Gear VR and Oculus, and it is very simple to use. First, press the MyLumion button, Set a Viewpoint, then click Render VR Panorama:

rendevr.png

For Oculus Rift, choose LumionVR to render an LVR file:

vrsettings.png

You can watch as the renderer works its way through the left eye and right eye:

vrrendering.png

Finally, open that file in the LumionVR viewer (included with your Lumion 6.3 installation) and interact with the scene using the Oculus Rift.

There are also some key aesthetic additions that became available during the releases of Lumion 6 through 6.3, and the imagery below gives you an idea of what each effect can accomplish once applied to your projects.

1-benchmark.png

After the benchmark you will be presented with this Start screen, which will allow you to quickly create projects for a variety of different scenes and enviroments:

Specific Tips and Workflows
We all work in different ways. And we all have our own artistic style. So when considering how to best integrate Lumion with an existing design and presentation workflows, there will obviously be some variations. But essentially, you will take models from a content creation suite (such as Revit) into Lumion, and then perform various tasks such as site modelling and adding entourage, after which you will tune various presentation style settings and export to a video or still image.

You can read a real world example of how UK architectural practice Lovelock Mitchell has made Lumion a part of their day-to-day design pipeline at this link. I could certainly identify with this comment that Michael Chevasco made in the article:
“If you like the visualization side of architecture like I do, then you might find experimenting with Lumion artistically rewarding, for example, positioning the sun just right to create a certain mood, or the getting the wind to blow through the grass in a scene. I enjoy those things and Lumion makes it easy.”

How to Use Lumion with Revit

Further reading:

In times past, I had this dream that Revit would be the sole answer to every single architectural and modelling question. Due to the proliferation of excellent addins and addons, I now realise that Revit is positioning itself as the operating system of the BIM environment. It has a solid parametric, data and intelligence engine, which can be extended in many ways through the expansive API. One area in which Revit has sometimes wavered is in pure visualization, particularly of the real-time and photorealistic variety. Using RPC and Realistic display modes within Revit can achieve a certain result, but here are some questions:

  • Is using an additional presentation package, like Lumion, worth it?
  • Will it result in a better visual result?
  • Will the performance be acceptable?

I received a review copy of Lumion 5.3, and tested it using Revit 2015 Update 7. As usual, I have reviewed the software, but at the same time I am sharing practical tips and guidance on how to get up and running with Revit and Lumion.

To start with, let’s consider whether Lumion can really add value to your current design and development pipeline. You may be thinking “I don’t have a clue how to make a fly-through animation“, but that is where Lumion lives. It makes it easy for you to take your BIM geometry, and put it into a real, living environment. In a sense, it is a ‘complete’ visual presentation package, as it includes things like environments, backgrounds, materials, weather effects, water, entourage, vehicles, people, trees, landscape, furniture, terrain modelling, and it is all in a package that allows you to modify, manipulate and tweak basically everything in real-time. It has a clean UI and extremely fast rendering capability. For output and deliverables, you can easily export still images or rendered videos of the scenes that you have composed.

You might be thinking “I don’t have time to learn yet another modelling tool“, but if you spend any time at all in post production software like Photoshop, 3ds Max, After Effects or something similar, then Lumion does not represent a steep learning curve. The interface is relatively unobtrusive and simple to understand. The Lumion addin allows for building models to be exported from Revit, but it also allows models to be updated and reloaded into the Lumion scene. As one person put it, “Use Lumion and Revit together and you will enjoy the synergy.”

You can check out a very concise ‘getting started’ style video here:

To put it simply, when you pair a powerful and parametric building design tool like Revit, with a free-flowing, smooth, flexible presentation software like Lumion, you have a very formidable design and presentation pipeline at your disposal. So, let’s learn a bit more about Lumion…

This remainder of the review has been divided into the following 5 sections:

  1. Download, Installation and Deployment
  2. Workflow (BIM friendliness)
  3. Performance
  4. Quality of Output
  5. Real-world applications and Case Studies

Download, Installation and Deployment:
Installing the Main application

  1. You will receive an activation email, with a unique download link
  2. Download and run the ‘download manager’
  3. Copy the activation code from your email to the download
  4. It will now automatically download Lumion, usually to your Downloads folder (about 4.94gb)
  5. You should copy the installation .exe and .bin files to some safe location – these are what you will use to install Lumion on other PCs
  6. The installer should run automatically – all you need to do is set the install path
  7. Start Menu – Run Lumion 5.3
  8. Agree to the Licence Agreement
  9. Lumion will now run some benchmarks and initialize itself
  10. Once the next screen appears, you will get a ‘system speed’ rating
  11. Note: I was expecting to see a Revit addin automatically installed… but I have since realised that this is an additional step… see below.

 

Installing the Revit addin

  1. You can get the Revit addin from: 1) the Lumion website http://lumion3d.com/revit-to-lumion-bridge, or 2) Autodesk Exchange – Lumion Collada Exporter
    (The version I installed was 1.4.4)
  2. Running this addin will export a DAE file, which can then be imported to Lumion

Licensing
Here are a few notes on how the Lumion license works:

  • The installer is specific for your Lumion License.
  • You can copy the Lumion installer to other computers or your network drive.
  • You may install Lumion on multiple machines.
  • When you start Lumion your license is flagged as in use.
  • When you quit Lumion your license is flagged as free
  • You need an internet connection in order to run Lumion

System requirements

  • Harddrive: 20GB of disk space
  • Using Lumion and Lumion Pro via Remote Desktop or similar virtual desktop solutions is not supported.
  • Lumion and Lumion Pro require an internet connection.

Workflow (BIM friendliness)
There are a number of ways to move data from Revit to Lumion, such as using DAE format via Exporter, or FBX via built-in export. The dedicated DAE exporter addin from Revit is the recommended method.

The Exporter addin (Revit to Lumion Bridge) works in orthographic 3D views and takes all visibility filters for the view into account. If you try to export from a Perspective view, the Lumion export addin will be disabled. However, in Revit 2015 R2 you can easily convert a Perspective 3D view into an orthographic or Parallel-3D View to allow export to proceed. Here’s how:

  1. Ensure that a Crop Region is applied and Visible, and the view is “unlocked”.
  2. Then, right-click on the View Cube and switch to Parallel-3D view, like this:

Then, run the exporter. The UI is relatively easy to follow:

I tested using ‘normal’ accuracy, and the file size result was like this:

You can then easily open or create a scene in Lumion, and then import the model you just exported from Revit:

Navigation
Once in Lumion, you can use the WASD keys to walk around, and QE keys to move up and down. If you hold the right mouse button and drag, this will change your view direction. Holding Shift will speed up your movement. It is quite a fluid navigation system. F1/F2/F3/F4 turns shadows on and off and makes other quality vs performance changes.

You can see other tips and keyboard shortcuts at:
LUMION 5: Quickstart Guide here forum.lumion3d.com/f-a-q/lumion-5-3-tips-tricks/
and
LUMION 5: Keyboard shortcuts

Placing models
It is easy to place models, just:

  1. Click the category (people, transport, landscape etc)
  2. Click Change Object to select desired model
  3. Click to place in the scene

 

 

To bring in external models, like DAE or FBX exported from Revit, use the Import models option.

Depending on how your model heights were configured in Revit, you may need to move your model downwards in Lumion. In my case, I had to move the model downwards in the Y-axis by about 150m (yes, Lumion understands the vertical to be the Y axis, not the Z):

To update the model, just re-export the DAE file from Revit. You can reload by: going to Import mode, selecting the spanner for ‘context’ menu, selecting your Model and then clicking on the blue circle, which will open up the context menu with the reload option:

It is interesting to note that even new objects (ie. newly added to the Revit model) that have a Revit material name matching a currently overridden material in Lumion, will then adopt that Lumion material when the import is reloaded. Nice!

There is a brief tutorial video on the Lumion to Revit workflow here:

Easy Architectural Visualization in 15 Minutes. from Lumion on Vimeo.

So, is Lumion able to do anything that Revit can’t do? In a word, yes. For example, it can handle things like sculpting large-scale terrain models very easily, as this demo shows:

Add to that: movie effects, ocean / water, the large model and material libraries, lighting effects, render quality, and the overall ability to transform a scene from a collection of polygons into something that more effectively represents the real world.

Performance
The Collada DAE export was very, very fast – under 1 minute for a 150mb Revit model. Accordingly, of all the file types that can be used to get data from Revit to Lumion, I would expect that the recommended and preferred method is via the DAE export in the free addin.

Quality of Output
Lumion is targeted at rapid, real-time, moving animations with models that may also be animated. So the result is usually something that looks very ‘alive’. Coming from an architectural background, you may initially be surprised at the overall ‘look’ of things and you might find it slightly cartoonish. However, I recommend that you give it a try and have a go at tweaking a few of the display settings.

It is very easy to create a flythrough or fly around animation. Just start the movie tool with the film icon, then create a number of keyframes as you would with other animation tools. Then, you can easily export to mp4.

Real-world applications and Case Studies
I tested using a medium rise model:

Once the model was imported, it was very easy to select entire materials and replace them with more appealing versions:

To delete models, you can remove them directly from the library and they will disappear from all scenes that they are currently placed in. However, you can also delete the model only in the scene you are currently working on, and it will remain available in the library for use in other scenes:

Chauviere from HKS said at one of the above links, “I don’t think many people know or appreciate the hard work behind optimizing 3D objects to low polygon count, and still have them look convincing. The amount of high-quality plants and 3D objects in the Lumion library that can be used is impressive.”

Summary of Lumion 5.3
In review, let’s consider some of the questions raised at the beginning:

  • Q. Is using an additional presentation package, like Lumion, worth it?
    A. Yes, it would be very difficult for plain Revit to deliver the same speed, quality, and content
  • Q. Will it result in a better visual result?
    A. When it comes to real-time scene export, a Lumion visualization can be much more alive and animated than a Revit equivalent. You can also easily deliver your scene as a selection of high quality images, or as a rendered video.
  • Q. Will the performance be acceptable?
    A. Yes, provided you have a decent CPU and graphics card (refer to requirements above)

Summary of each section:

  1. Download, Installation and Deployment – 7/10, necessary to manually install addin
  2. Workflow (BIM friendliness) – 8/10, support for updating changed models
  3. Performance – 8/10, much improved in more recent versions and fast export to DAE
  4. Quality of Output – 9/10, smooth and appropriate for the visual style
  5. Real-world applications and Case Studies – 9/10,
    (see links above to see how companies are using Lumion)

My overall software score for Lumion 5.3 is 9/10. Its definitely worth a look if you do any kind of presentation work with 3D models!

In a future post, I want to look at the large-model workflow from Infraworks to Lumion via FBX.

Important notice:
If you migrate your work from earlier Lumion versions take into account that the material system has been changed in Lumion 5. This requires you to re-apply the materials to your objects.

How to delete objects?
You delete imported objects by using the Imported Objects Library.  It cannot be deleted from the Library if you have a scene open and using that object, so first clear and start a new empty scene.

Then in Build Mode click on Import button –> Change Import Object –> locate your object to delete and doubleclick the Rubbish bin.  That will permanently remove the object from the library and the files.

Information related to older versions
I have been familiar with Lumion for some time.  A full scale Lumion review has been on my radar for a while, but like anything, it takes time to have a proper look at a piece of software.

My past experiences with Lumion had been hampered by less-than-stellar hardware.  You really do need a decent workstation to have a fluid and productive time with Lumion. In my case, my new workstation at Virtual Built has 64gb of RAM, a 6 core (12 hyperthreaded) processor, and a Quadro K4000 video card.

I previously posted about Lumion at:
What Revit Wants: Real-time visualization with Lumion

I have previously posted about the future of real-time visualization tools.  Lumion appears to be developing a bit of a following.  Have you used it?  How did you implement it?

If you haven’t seen what it does before, there is a set of videos at this link:
Revit Landscape – Urban Design: Lumion 3D

If you want to see a project go from Revit to Lumion (also this thread):

A free version for non-commercial use is available from this page.  The free version will apparently be updated to version 2 in January 2012 (only a few days of that month to go…)

The company line:
Lumion® is a real-time 3D visualization tool for architects, urban planners and designers.
It’s perfectly suited for creating videos, still renderings and live demonstrations with a quick turnaround.
Lumion offers excellent graphics in combination with a fast and efficient workflow, saving you time, effort and money.
It is in fact so easy to create awesome still renderings and videos with Lumion® that it almost feels like cheating.
