[vtkusers] Re: Depth sorting and intersecting polys

[Goodwin Lawlor]

Hi Arnold,

Try using vtkPolyDataNormals with ConsistencyOn. Also if you're rendering
triangle strips, try rendering just triangles (filter with
vtkTriangleFilter)

Hi all,

I'm trying to render some polydata with transparancy.
I'm using vtkDepthSortPolyData to sort the polys
such that transparancy appears (sort of) ok. However,
there are still some strange effects in the result. I
guess this is due to overlapping and intersecting
polys. Is there a class which splits such polys
into smaller (non-overlapping/intersecting) ones?
Or is there another way to solve this?

Regards,
