Hi,
Given a subdivmesh polygonal cage, is there a way to approximate the
underlying limit surface with NURBS surface?
This question came about because I could not find any library (open
source) which allow me to easily query the limit (1) position (2)
normal and (3) derivates [1st & 2nd order], at given UV location on
SubDiv mesh. I have read Jos Stam and other papers but due to time
constraint and terrible maths knowledge, I cannot divert my attention
to SubDivMesh exact evaluation R&D. Some of such code may be present
in open source renderer e.g. Pixie, but they are not expose as library
API which are easily callable.
Since since such query is available in NURBS e.g. NURBS++ or
OpenNURBS, I thought I might solve the problem indirectly.
Regards
