Volume Rendering Demo Accelerated by GPU
Posted by JeGX in 3D Engines, tech demo, tags: demo, gpu, linderdaum, opengl, raycasting, volume rendering
Here is an OpenGL demo that shows a raycasting volume rendering accelerated by GPU. This demo uses voxel 3D datasets from computed tomography. The demo is based on the Linderdaum engine, an OpenGL 2/3 rendeing engine with industrial and scientific volume rendering capabilities.
You can download the demo HERE.
On my GeForce GTX 280 (ForceWare 186.15) + Core2Duo E8400, the demo runs at about 1200 FPS.

Great Job!!!

Well, FPS is really meaningless without specific details of rendering settings; for example, 1200fps is quite slow for let say 300×300 projection plane, tiny volume (256×256x256), sampling density 1 sample per cell and very high opacity settings – near iso-surface and. To be meaningful, FPS numbers should be accompanied with correspondent interactive images and dataset specs.
