CGTalk - Tornado (vfx shots)

These are a couple of shots we produced for an internal corporate video, involving a hallucination sequence where a worker gets ripped out of his cubicle by a tornado.

It's our first production use case of a new physically based volumetric render engine for Blender that we've been developing here at ProMotion (http://www.promotionstudios.com). We modelled the set from photos and matte paintings, and the tornado was created with several particle systems. We rendered it in HD as a volume, using a mixture of several 'point density' textures (creating density information from point clouds), alongside procedural textures, and procedural displaced turbulent detail. The source code is available, as are development builds for testing. If you have any questions about the system, feel free to ask!

hi, great job on the Tornado.
Considering you guys are coding the volumetric solutions yourselves in Blender,
even more impressive.

wow, great work, difficult shots to have a really good time.
The main tornado look is volumetric shader or sprite?
Poor guy, he's drunk or something!

Hi!
Really cool stuff and seems like you've put a lot of work into this. Now, I don't know a lot about 3d and even less about blender, so i don't know how complicated this would be to do, but it seems to me like you should have the tornado cast some sort of shadow. It looks really good, but it seems like it has little if any effect on the light reaching the floor where the worker is sitting. Basically, it just has a bit of a... 'pasted on' sort of look? But the animation and the rest of it is really awesome :)

Hope this helps.

Very cool stuff. This guy must hate his job because I've never seen someone so happy to have their building destroyed :eek:
