Hi All,

I am looking to extend a VTK based decimation algorithm to support texture maps. I can see that vtkQuadricDecimation class contains functions relating to TCoords e.g. SetTCoordsAttribute(vtkTypeBool), however vtkDecimatePro and vtkQuadricClustering don’t.

Does this mean only vtkQuadricDecimation supports texture mapping ?

Also, will the texture mapping be automatically re-applied to the PolyData by the decimation algorithm after decimation ? Or do I have to do this manually ?

I look forward to your reply

Kind Regards

Famous
