[vtkusers] vtkGPURayCastMapper

[Martijn Steenwijk]

Dear all,

 

I'm using the vtkGPURayCastMapper for volume rendering. However, when I
change lighting and shading options (such as SetDifffuse, SetAmbient,
SetSpecular, SetSpecularPower, etc) , the renderer renders the scene in gray
colors - while CPU Raycasters do this not.

 

Does somebody has a suggestion to fix this problem? I'm using Win7 64-bit
equipped with an ATI radeon HD4870X2. 

 

Best,

Martijn
