Description:
|
If a spline surface consists of a rectangular array of simple patches, each rectangular in parameter space, returns the number of such patches in the u parameter direction.
|
|
|
What is considered a "simple" patch is open to interpretation, but with a piecewise bipolynomial surface (such as a B-spline), each bipolynomial piece would be a reasonable choice.
