Subject: convert trimmed nurbs surface to bezier patches
I wonder how the trimming information is reduced accordingly into these
1. convert the nurbs surface to bezier patches
2. convert trimmed nurbs loops to bezier curves
However, each bezier patches have their own parametric
representation(say uv) ranging from 0 to 1.
So how do we determine if any of the bezier curves belongs to the
boundary of any of the bezier patches?
Please correct me if I am wrong.
