# IGESGeom_OffsetSurface Class Reference

defines IGESOffsetSurface, Type <140> Form <0>
in package IGESGeom
An offset surface is a surface defined in terms of an
already existing surface.If S(u, v) is a parametrised
regular surface and N(u, v) is a differential field of
unit normal vectors defined on the whole surface, and
"d" a fixed non zero real number, then offset surface
to S is a parametrised surface S(u, v) given by
O(u, v) = S(u, v) + d * N(u, v);
u1 <= u <= u2; v1 <= v <= v2;
