[vtkusers] vtkStripper too slow

[Pelt, R.F.P. van]

Dear all,

 

I'm trying to create a vtkImageWidget, which renders on the GPU.

Therefore I have a Volume and VolumeMapper for the rendering of the
plane, and

I take a vtkPlaneWidget to control the plane orientation.

 

I've got the concept going, but it's rather slow. The bottleneck is the
vtkStripper.

For each frame I take the output of the vtkCutter to get the polygons of
the

image plane in the current orientation. Next, I use the stripper to
transform

this to triangle fans, so that I can render this with OpenGL immediate
mode.

 

Is there a faster way to get the polygons rendered with OpenGL.

(I need this to add texture coordinates for the GPU rendering).

 

Thanks!

 

Regards,

 

Roy
