class OffsetSurface from IGESGeom inherits IGESEntity
|
|
|
|
---Purpose: 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;
