Volume Rendering Demo Accelerated by GPU


Linderdaum demo - Volume Rendering with GPU



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.

    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 (256x256x256), 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.

    When you don´t move the image this program runs at 600~1200 fps on any system because it only renders the scene once (shows the same image over and over), if you want to perform a benchmark leave the light movement activated (that forces the program to render the full scene for each frame) and you will notice a substancial framerate drop of about 90%.
