[vtkusers] Texture Coordinates

[Eric E. Monson]

Hello Ayman,

The texture coordinates should be associated with the PointData of your PolyData, rather than the actor. You should be able to check and see if there is anything assigned (but I've never tried this as a test for existence, only to get the coordinates I knew were there):

polydata->GetPointData()->GetTCoords()

Talk to you later,
-Eric

My Actors have associated vtkPolyData that is  constructed from a Reader (.vtp, .obj) in case it matters.
