vtkTube : Quadrilaterals instead of Triangles ?

Hi,

Currently, using vtkTube generates triangle mesh/strip

VTK_Tube_Current

Is there a way to influnce vtkTube to generate quads ?

I assume you mean vtkTubeFilter.

Quads don’t work in most cases, for example when the generating polyline is not straight. In which case the combined curvature of the tube and generating polyline produce non-planar quads - which are undesirable.

If you want to create something like what you’ve shown, maybe one of the extrusion filters would work for you.
