Detailed Description

Defines an offset surface.

An offset surface is defined by a basis surface and an offset value.

The following image depicts an example of an offset surface:

Offset surface

A basis surface must be at least G1-continous, otherwise behavior is undefined (most likely an exception will be thrown).

An offset surface is parametrized as follows: \(\mathbf{S}(u,v) = \mathbf{B}(u,v) + \mathrm{offset} \cdot \mathbf{N}(u,v)\), where

  • \(\mathbf{B}(u,v)\) is a basis surface;
  • \(\mathrm{offset}\) is an offset value;
  • \(\mathbf{N}(u,v)\) is a unit normal computed on basis surface;
  • \(u\) and \(v\) belong to basis surface domain definition.
Examples
exploring/brep_geometry/Program.cs, and exploring/brep_geometry/main.cxx.

If theBasisSurface is an offset surface then its basis surface will be used as a basis surface and offset will be a sum of theOffset and the offset value of the theBasisSurface.

theBasisSurface must be at least G1-continuous, otherwise behavior is undefined. Constructor.
