Detailed Description

Core mathematical kernel for Gordon surface construction via the Boolean sum method.

Accepts pre-compatible BSpline curves (same degree and knot vector within each direction) and intersection parameters. Builds three intermediate surfaces (skin profiles, skin guides, tensor product) then computes the Boolean sum: S_gordon = S_profiles + S_guides - S_tensor

This class can be used independently when curves are already compatible, or via GeomFill_Gordon which handles curve preparation.

Supports closed (periodic) curve networks when the first and last curves in a direction are geometrically identical. The closedness flags enable C2-continuous periodic interpolation during skinning.

Limitations:

• Non-rational curves only
