Description:
|
The curve is offset in the plane in which it lies, and either to the right (or left) as viewed along the curve. If an error occurs, a
NULL curve is returned.
|
|
|
The
plane_nor argument supplies the plane normal, and is used only for linear b-spline cases. In all other cases
plane_nor is ignored.
|
|
|
Errors:
|
If the spline is linear and
plane_nor is not specified, the function returns a
NULL b-spline (unsuccessful).
|
|
|
|
If the given B-spline is a degenerate B-spline the function returns a
NULL B-spline (unsuccessful).
