What hardware support do I need to run OpenGL Volumizer?
OpenGL Volumizer 2.x uses 3D texture mapping in order to substantially improve volume rendering performance. Consult output of ‘hinv’ and ‘gfxinfo’ commands to find out if your machine supports hardware texture mapping. Specific volumetric shaders might rely on certain OpenGLĀ® extensions to be supported. See the release notes for a detailed list.
