Description:
|
Adds knot to a surface up to the requested multiplicity with in the given knot tolerance. This routine returns the number of knots added.
|
|
|
The input parameter has to be with in the parameter bounds of the given surface. The final multiplicity of the added knot cannot be greater than the degree of the surface in the requested direction.
|
|
|
Use the tolerance to distinguish between the knots. It is used to test whether the knot being added already exists.
