Volume Rendering

Shading Volumetric Data



• Density gradient is normal to surface, dot with light
• Can be done on host
  • Convert data: find gradient, dot with light direction
  • Redo when light or object changes orientation
• Use OpenGL pixel path
  • Convert data on host, find gradient (or bump map!)
  • color_matrix extension to compute N • L
