IGESGeom_SplineSurface Class Reference

defines IGESSplineSurface, Type <114> Form <0>
in package IGESGeom
A parametric spline surface is a grid of polynomial
patches. Patch could be of the type Linear, Quadratic,
Cubic, Wilson-Fowler, Modified Wilson-Fowler, B-Spline
The M * N grid of patches is defined by the 'u' break
points TU(1), TU(2), ..., TU(M+1) and the 'v' break
points TV(1), TV(2), TV(3) ..., TV(N+1).
