[vtkusers] How to add actinomorphic texture on a cirque?

[fofo]

Hello, everyone！
	I want to draw a true to nature iris with vtk. The vtkDiskSource was used as data source.But I don't know how to add texture on it. I have test all vtkTextureMapTo***, only the vtkTextureMapToPlane can work. But it makes the texture images arranged on the disk plane horizontally and vertically, not actinomorphicly.
	The image I got was attached. Please give me some advices. Thanks lot!
