I need some links or advices on NURBS, T-Splines, subdivision surfaces and related stuffs. I try to evaluate possibilities for modeling and rendering surfaces (and curves).
Subdivision surfaces and b-splines surfaces are closely related. Relatively to my project, NURBS are useful because they are invariant under projective transformations (common with interactive rendering) and they can represent spheres and other conics without approximation.
Is there some subdivision surfaces with the same properties ? Is this impossible ?
What is the most simple scheme with projective invariance ?
Anything related to this subject, feel free to answer or ask any questions.
