The Bunny of Doom

A teaser video for our research project on fast 3D mesh extraction from volume data. ;) The frame rate shown is for extracting a triangle mesh from volume data, using an NVidia G8800 GPU and our marching cubes algorithm (which _does not_ use the geometry shader).

On top of this, we implemented a particle shader for the burning effect.

If you are curious, check out

Sourcecode sits on http://nvision.sf.net

rocks;) how did you do it? shader + particles?

You mean the burning effect? Since the GPU generates the triangles (from a tomography volume), we use the OpenGL extension "transform_feedback" to protocol the triangle stream - and then we add their vertices to a GPU "fire" simulation, based on a GPU particle simulation... :-)

i don't quite know openGL:)) I'm currently learning directX...but anyway, you guys got it cool. I got a particle system of my own...i'll probably post a vid soon...i hope:D

[foreignaustrian]

go for it! there´s plenty to do already, and more features are yet to come in hardware :-)

3D Bunny + Oldschool fire demo effect = Wicked stuff ! B)

well,I'm currently trying to solve a problem with the "attract to point" part of the system...but i can't seem to make it work properly...it produces a pretty cool effect...but not exactly what i wanted....x-(

Pretty cool :))
