3D ArtRoom 2022 – Update

I reworked the ArtRoom, which I revived, and re-baked and exported it from Blender to BabylonJS, to the glTF (.glb) file format specifically from Blender.

I mainly added plates to put my photography on. I also tried to put a dedicated environment into the scene, but somehow the .babylon file is broken after exporting it. What I did is drag and drop the Blender export onto the BabyonJS sandbox and saved it as BabylonJS and glTF. But for some reason the environment did not come across.

But since I set all objects to «unlit», this doesn’t really matter that much.

Update April 16. This above is a heavily optimized version. A bit more moody, smaller textures and reduced figures polycount more manually. Basically the file went from 96 MB to 2 MB. Workflow seems stable.

I export from Blender using the built in glTF exporter, import that into the BabylonJS Sandbox, tweak a few things and export it from there. A very big help in all my work going to JPG is Greg Benz’s WebSharp PRO. Highly recommend adding this to your workflow as well!

Create your own environment (still unsolved)

So, technically, to create an environment go here.


  • drag and drop a hdr image
  • save the env
  • drag and drop the saved .env scene onto a sandbox scene

    But as said above, somehow the exported scene is broken. It cannot be re-imported to the BabylonJS sandbox…

Next Steps

  • Next step would be to code it up and make the images clickable.


I have always looked for possibilities to display 3D content on the web. Many authoring software packages or plugins came and died. Now there’s a new initiative that looks very promising. Modern, sexy (yes, I still use that description, sue me!), easy, flexible and just cool.

It’s called BabylonJS and you can find all information about it at their website.

Together with Blender3, the Blender BabylonJS Export plugin and the baking plugin BakeTools one is up and running very fast. Here’s a good tutorial on how to export from Blender using this plugin. I also just found this here. I will give it a try on my next run at this.

It’s then very convenient to load the exported scene into the BabylonJS sandbox where textures can be loaded or replaced and the materials can be tweaked. Plus there’s a lot more settings that can be set. Like how far down the user can tilt the camera, or add a dedicated environment and much more. And the Java capabilities of the Framework the sky is the limit 🙂

Also there’s a WordPress plugin to display your models on your website, stored local or in the cloud! Actually there is two plugins. More about them here.

Example; ArtRoom 2022 (revived)

I revived a project I did with Vera Liechti many years ago. We entered an exhibition contest and wanted to present Vera’s oil paintings interactively. Meaning we built in a stereo camera (something like a kinect) and the visitors could interact with the artwork by moving their body. The visitor could then step on a button and the version of Vera’s painting would have been printed and the visitor could take that print home. Here’s the PDF we submitted. Unfortunately we were not accepted. We had a working prototype. Here’s the previz data from then now reworked in Blender and exported to Babylon JS.

Blender «BakingTool» Addon

While getting nice results with the built-in baking in Blender, There’s no way to denoise the renders while rendering. That’s not a biggie, as the compositor can easily be used to denoise the results.

But the baking is sorta cumbersome and very manual. So I was looking for a solution that would automate this a bit. First I tried this GitHub project called «Lightmapper«. But even after hours of testing, running various Blender versions etc. I simply did not get any images out of it. It rendered for 0.0 or 0.01 seconds and nothing. I am sure I missed something, but as it looks like a cool solution. Give it a try! Projects like those are not priceless because they’re free, but many times they combine the best of many commercial tools. But there’s always the «which version of host app to run with which version of the code» problem. Which is not the case with commercial products.

So I found the apparently most well known Blender baking tool called «Baketool«. Bought it, installed it, played with it, consulted their documentation and watched a video or two and I was up and running and it rendered images in no time.

While there’s more than «Baketools» and the Github project «Lightmapper», I am happy with my purchase of «Blendtools». I found my list here. Give it whirl, you might find something that suits you.

Final bake in Blender (left) and the in the BabylonJS Sandbox (right)

Side note: I added a point light for more illumination than just from the neon tubes with an emissive material. And also a spot light to bake the figure.


The process is very easy with this addon.

  • Create a new Job
  • Decide the baking mode (Individual or Atlas & Target)
  • Setup mode, save path, Image format and render device
  • UV settings (Good at default)
  • Then add the object you want to bake
  • Choose the render passes
  • Hit «Bake»

My setup

  • Created a job called «ArtRoom-2022_REGULAR»
  • Chose to bake individual surfaces to texture
  • Enabled «Expert» because it has more options
  • Set path, chose PNG and CPU (with my 1060 there’s not much difference to CPU…)
  • Added all the meshes I want to bake
  • Setup AO and Diffuse pass to be rendered (more samples on AO for less noisiness)

Blender «Little Planet» Tutorial

On my journey to learn Blender I found this tutorial by Studio Gearnoodle on Youtube.

I took the opportunity to practice modelling, animating and lighting techniques I learned so far and model my own mushrooms and buildings. Basically I am trying to apply the knowledge I’ve acquired for the past 25 years doing 3D to the Blender interface.

I gotta say, Blender is on to something here. They really are taking the right direction and are providing a full fleshed package and with their philosophy of «everything nodes» the potential is huge. And free! Yes, OpenSource!

«Unleash the beast» – Houdini

On my journey to leave Maya behind me and not being involved in any 3D production work I started to learn some Houdini.

Since I saw it the first time back at Siggraph in 1996 I was drawn to it. But my professional jobs never left any time to dig into it.

I really love Houdini and I find it the best package out there. But… It became very clear very fast that to become proficient in using it would need a large junk of time.

Nevertheless here’s my interpretation of a tutorial by Nine Between.

Institute of Pharmacology «T-Cell Animation»

This is an animation showing a T-Cell that connects to a cell and is able to discharge when the cell is not covered with sugar crystals but fails if the cell is completely covered.

From Autumn 2019 until Summer 2021 I worked in the research group of Prof. Stephan von Gunten at the «Institute of Pharmacology» at the University of Bern, Bern Switzerland, as a 3D instructor and animator.

Institute of Pharmacology «Virus Animation»

This is an animation about the process of a virus docking to a cell, entering the cell and getting the cell to replicate the virus multiple times and the replicated viruses exiting the cell.

From Autumn 2019 until Summer 2021 I worked in the research group of Prof. Stephan von Gunten at the «Institute of Pharmacology» at the University of Bern, Bern Switzerland, as a 3D instructor and animator.

Unity Engine Evaluation

After completing the work for the AAS demo of the NYWF project we crawled back to our cave and started questioning whether it’s a good idea to continue working with the Ogre 3D engine.

We built small tiger teams to evaluate 3 – 4 engines. Unreal, CryEngine, Trinigy and Unity.

I took on Unity and rebuilt parts of the fair from the content we have from the AAAS demo.

Unity is a very modern game engine. It supports all the new devices and platforms. It’s very convenient since authoring one game means you’ll be able to deliver on several platforms.

The downside of Unity is the lack of support for industry standards like LOD switching as well as an integrated node based shader editor. For things like that the users of Unity have to rely on the community. While there are tons of such micro solutions out there, there’s no way any game studio would rely on third parties to continuously support such tools on their own. «You get what you pay for» comes to my mind. And «OpenSource is freeware»…

We decided to keep going with Ogre3D mainly because of licensing issues. While all engines provide an EDU licensing scheme, that scheme is meant to be for educational purposes only. As long as you distribute your game for free, you might use the engine for free. But since our final deliverable is going to go into museums where people pay admission, we had to drop almost all of the engines immediately.

Here’s a few more images from my exercise

Proxy buildings using LOD’s in place

Here are some shots of the New York World’s Fair proxy simulation I built. The idea behind this was to get an estimate on how many polygons the Ogre engine can take and also it should be used as a playground to implement gameplay mechanisms.

The 3 LOD’s range from 50’000 (low level, pink) over 1.8 million (medium level, green) to 15 million polygons (highest level, turquoise). If all of either LODs is loaded at once that is.

In most cases only the very close buildings are seen in the highest level of detail.

While visually not very attractive this was a good footprint of the complete product and a great test-bed.

LEGO Research Showreel 1995 – 1998

This is where it all started…

This video is from the time at LEGO (1995 to 1998) and shows work Dan and I were involved in during this time. It documents what was happening in respect to human interaction in 3D space at LEGO and goes all the way to real time movie making with digital LEGO. It visualizes the vision we carry when we create a product like Xaelander for Motion4U.

The very first bit of the video shows an early prototype that was realized in collaboration with David Small which was at MIT at this point. As soon as the gentlemen in the yellow suit pops up you’re looking at Scott from Multigen that uses SmartScene. In the second part of the video there is footage from the castle demo of the WIZard group at SPU Darwin (actual name of the demo was «Batlord’s Castle»). In there you will also see Kjeld Kirk Kristiansen the owner of the LEGO Group (gentleman in the blue-shirt with tie and the VR headset).

So if you’re in for the short read, watch the vid, follow the links above and check out what you can get out of this today. If you care about background, history and tech-babble … keep on reading 🙂

Xaelander – Previz in Maya

I just completed recording a small animation in Maya using the new Xaelander X2R2 hardware testing the upcoming Xaelander software release.

I think it documents nicely what the Xaelander software suite is capable off. It demonstrates animating a walk cycle on the primary character and animating the secondary character. The powerful two point 3D camera tracking and animating a special effect by capturing motion onto a locator.

I look at the short video and think «Even if I captured every part ten times, I created that animation in about 20 minutes. An experienced storyboard artist could probably come close nailing that shot in 20 minutes. But a previz animator should never ever have to just float his characters around anymore – they should make them walk around.»

Ogre3D DCC Wiki

I am involved in project that is rebuilding the New York World’s Fair from 1964/65 in 3D. Read more here…

We are using the Ogre3D engine to render the ‹game›. Producing into a OpenSource engine is not always easy because sometime the tools to export models from 3D modeling applications and many other aspects of a content creation pipeline that is available through the community are outdated or simply don’t work. Ogre3D is a well spread engine by now, but most studios that work with it keep their tools and solutions close to their chest.

Wiki on Ogre3D and more…

In the spirit of the NYWF (New York World’s Fair) project which is funded by the NSF (National Science Foundation) I’m going to provide the solutions we come up on a Wiki for everyone to follow, use or even extend.

Motion4U @ Siggraph 2009

We had our own small booth @ Siggraph 2009 in New Orleans. And yeah the gorgeous woman in the gold suit belonged to us 🙂 I am amazed how underrated the «booth babe» concept is these days.

Microsoft Natal

Just a short note on this «new» technology.

Microsoft has started to attack the Wii from Nintendo with the project Natal. Read More…

I remember seeing a video that showed someone sword fighting with his finger and of course I saw Bill Gates Talking at the D5 conference in 2007 about his «last» vision for Microsoft is in Vision Programming.

quote: «So 3D is a way of organizing things, particularly as we’re getting much more media information on the computer, a lot more choices, a lot more navigation than we’ve ever had before. And we can take that into this communications world where the PC is playing a much more central role, kind of taking over what was the PBX, sort of one of the last mainframes in the business environment. That will be a big change that will come to it. And as we get natural input, that will cause a change. … Software is doing vision and so, you know, imagine a game machine where you’re just going to pick up the bat and swing it or the tennis racket and swing it.»

Natal is the first device that will actually release that does marker less tracking in an affordable price range. Of course there was the Z-Cam from 3DV, but now that Natal has surfaced it’s clear why Microsoft has bought them up.

I hope that their developers come up with more creative ways to use the motion interaction as some developers do for the Wii.

Google released open-source 3D API for the web

Could this be the one that changes the game? Google has released a 3D API, Quote by Google: «O3D is an open-source web API for creating rich, interactive 3D applications in the browser. This API is shared at an early stage as part of a conversation with the broader developer community about establishing an open web standard for 3D graphics.»

We’ve seen many formats and efforts of bringing 3D to the web in the past. At the begining there was vrml 1.0. I was very excited and built a lot of things in Power Animator and exported it to vrml inclusive authoring. Vrml 2.0 had animation, multi textures on one node and many more features like proximity sensors and 3D sound. I was especially impressed by «Floops» (unfortunately I found no usable links on Floops – anyone – comment?) created by Brad de Graaf for SGI (Silicon Graphics).

Later on vrml was replaced by X3D. X3D is an xml based file format and was supposed to widely spread and the plans were to create exporters for many applications in the animation and cad sector.

I’ve played with X3D and the Flux Player. Flux Player now merged into Vivaty but is still available to download here. I will put my experiment online soon… Stay tuned.

I am really hoping that this will finally kick of some serious business for 3D on the web. It’s about time I think. The bandwith, the gfx power on peoples machines and the technology is here. Now that Google has picked it up it has a real chance to succeed. What do you think?

Motion4U – What is BurstMode?

Here’s a little flash anim posted for historical reasons and sharing.

It’s explaining different operations that can be done in BurstMode.

Left Mouse Button = Object Manipulation
Middle Mouse Button = Camera Manipulation
Right Mouse Button = Burst Fly Mode

LEGO – squash and stretch to the ugly…

I wrote up an article one day because I am constantly getting annoyed by the ignorance of producers and animators towards the legacy of Godtfred Kirk Christiansen the son of the founder of the LEGO Group. To me the LEGO figure is molded with rigid plastic. Bringing those figures to live by deforming them destroys the look and feel. Read it here…

Now this Intro page to the upcoming LEGO 3D Digital Universe is probably the worst I have ever seen. Watch the mini figure in red dancing and bowing, errrmm… hitting his head to the floor. And mind the broken geometry on the arm when he’s waving…

Here’s a screencapture (1.8 MB QuickTime movie) of  the LEGO Universe Intro (In case it changed…)

Here’s a more elaborate 3rd party article on the LEGO Universe followed by a very good comment written by a fellow co-worker at SPU Darwin and a dear friend of mine Christian Greuel. (NOTE: This is coming from the web archive website. Please be patient, it will load for a while.)

Porsche Design – Worldtimer

Two of the biggest challenges in creating watch animations are that most likely if you get to animate a watch it means it doesn’t exist yet. So you got to cobble together the look of the real material in that particular shape and finish. The other challenge is the that most watches are only visible because they reflect their environment. Now to do that for still shots is somewhat easier than animations because, even in real life, reflections on such a small object can become erratic and you end up animating the environment which can make the 3D scene somewhat complex.

Here’s the three 3D animation we made as freelancers for MDI Production in Neuchatel/Switzerland in collaboration with two freelancer animators from France, Geoffrey Dupuy (Storyboards, 3D animation) and Nicolas Parreira (3D animation, Expression setup, materials, rendering). The AfterEffects work was done by Mathias Schmid who was in his last weeks of his apprenticeship as a media designer at MDI.

I was supervised the project for Franco. COnverted and prepared all the models from CAD to Maya. My main focus was on animating, texturing, lighting the Porsche Design Worldtimer and i was responsible for rendering all the animations on the 30 CPU render farm. I basically slept next to 8 PC’s setting the alarm clock every 2 hours. Yes, it was hot and noisy.

Lightwave Test

After doing the last watch animation in Lightwave I did a small test in Lightwave at home. I think Lightwave is a very good software. The main reson for me to get into Lightwave tho is that it has this very impressive plugin renderer that really blew my mind.

I tempted to underestimate anything else than Maya but I had to learn a lesson. Once you overcome the horrible interface you will meet a lot of stability, expandability and ease of use.

This is just a stupid test but the main thing for me was to do an outdoor scene using fPrime.

3D Internet – The future?

What if a website would be completly in 3D? I made the experiment and created this test using the X3D modeling package called Vizx3D. Media Machines (Tony Parisi) acquired Vizx3D and released later an application called Studio3D based on X3D.

You will need the newest installer to play this experiment. Get it here. Vivaty has taken over from Media Machines and has finally developed a plugin that also works in FireFox.

Update January 2016: Vivaty was bought up by Microsoft and their products and gallery were discontinued. More info also here. The player is now downloadable as part of this package.

Note: If you install the «SetupFluxPlayerStudio2-1.exe» from this package it will install the Flux Studio 2.1 and the Flux Player. Flux Studio is an interactive X3D authoring tool.

Warning: Although the Flux Player install will crash and report that FireFox is open and the plugin cannot be installed, the player will be installed. You can find it in the start menu under «Media Machines, Inc». I can confirm that it runs on Windows 7.

If you run it you can then open the URL: http://fullframestudios.ch/AREA/X3D/files/index_04.x3d to see the demo I did 8 years ago.

Be aware, this is completely experimental and I don’t take responsibility if it crashes your computer.


My basic idea was to transport the regular experience of browsing a website into 3D space plus add a little more excitement.

RoninWorks – Rattle – Promotional Video

Moving an object around in 3D space can be a tedious and annoying process and is definitely not something a baby could do with todays versions of tools like Maya, 3DS or alike. But with the immersive tools from RoninWorks even a baby could animate a shaking rattle more dynamically.

Watch what happens when a baby discovers full 6D motion interaction.

(And yeah, after hearing this over and over again for 3 full days, exhibiting at Siggraph, we had a rather ballistic attitude towards crying babies…)
