[vtkusers] create a texture map for an arbitrary surface

[Tim Hutton]

Hello vtk users,

I would like to create a texture map for an arbitrary polygonal surface 
(for example, to enable painting of any 3D object) - is there an easy way 
to do this in VTK? I don't want to use vtkTextureMapToPlane or similar 
because these don't guarantee a unique bit of texture for each part of the 
object.

My thought is to simply map the list of triangles (ideally polygons) onto 
the unit square using a grid layout, and use that for the texture 
coordinates (duplicating vertices as necessary). Has anyone done something 
similar? Would such a class be useful in VTK?

Thanks,

Tim.
