Volume Visualization on the Radeon®

The RadeonVolVis uses EXT_texture3D to demonstrate volume visualization in OpenGL®. For more on Volume Visualization and other uses of 3D textures, see our 3D Texture Mapping Tutorial. This sample shows a volume being drawn as textured shells. It displays with both a monochrome and a pseudo-color version of the volume. Additionally, the user has control over a clip plane to interactively slice the volume
