[vtkusers] Least square sphere, cylinder and cone.

[Bernard DUCELIERIN]

Dear all,

I am making an application where I need to compute
the best plane, sphere, cylinder or cone from a set of 
point. I found in vtkTextureMapToPlane.cxx the method to 
compute the least square plane, but nothing for sphere,
cylinder and cone.

Does anybody know where I could find in VTK (or anywhere
else) something to least square sphere, cylinder and cone ?

Best regards.
