[vtkusers] Problem with rendering Volume and Textured Plane

[Niels Bakker]

Hi Praveen,

To my knowledge I am not using openGL. For the volume I am using a
vtkVolumeRayCastMapper added to a vtkVolume. For the plane I'm using a
vtkPolyDataMapper and a vtkTexture added to a vtkActor. Both are attached to
the same vtkRenderer.

Its still a mistery to me.

Niels

(-:-) Hi Niels,
(-:-)
(-:-) Not sure how you are rendering the volume (using the ray-caster or the
(-:-) texture mapper), but this seems to be an OpenGL state issue. Make sure
(-:-) that you have restored your OpenGL state (the state that you
(-:-) modified like
(-:-) blending functions, etc) after you render the volume data.
(-:-)
(-:-) Cheers,
(-:-) Praveen
