[vtk-developers] volume rendering composite blend mode with foreground traslucent polygons

[Brad Hollister]

Vtk 7.x apparently can't render transparent foreground polygons with 
volume rendered voxels using composite blending.

The transparent foreground polys get rendered behind volume rendered 
voxels (which is incorrect depth). If those same foreground polys are 
fully opaque, then the composite blending is fine.

Any solutions, workarounds or fixes?
