class ProjectOnPlane from ProjLib inherits Curve from Adaptor3d
|
|
|
|
|
|
---Purpose: Class used to project a 3d curve on a plane. The
|
|
-- result will be a 3d curve.
|
|
--
|
|
-- You can ask the projected curve to have the same
|
|
-- parametrization as the original curve.
|
|
--
|
|
-- The projection can be done along every direction not
|
|
-- parallel to the plane.
