Description:
|
Creates a bi-cubic Hermite interpolant using a mesh of points, u tangents, v tangents, uv twists, and the corresponding knot vectors.
|
|
|
Errors:
|
If an error occurs, the function returns a NULL surface.
|
|
|
Limitations:
|
No two adjacent points to be interpolated can be same within tolerance. However the interpolated points can be same at start and end for closed surfaces, so other types of configurations are allowed which result in self-intersecting surfaces.
