[vtkusers] Volume Rendering Using Maximum Projection

[Praveen Bhaniramka]

Hi Asad,

Depending on what hardware platform you are using, you should be able to
use texture mapping to do the volume rendering with maximum intensity
projection simply by changing the OpenGL blending equation to
glBlendEquation(GL_MAX). The default value is GL_FUNC_ADD.

Cheers,
Praveen
