IGeom3DSpline::IsLeftHanded
Description
This method allows you to indicate whether the parameter coordinate system of the surface is right- or left-handed.
Syntax
Status = IsLeftHanded ( );
|
Return: (Boolean) Status |
TRUE (=1) if left-handed |
Note
With a right-handed system, at any point the outward normal is given by the cross product of the increasing U direction with the increasing V direction, in that order. With a left-handed system, the outward normal is in the opposite direction of this cross product.
