NURBSSurfConstPoint : NURBSPoint

This class defines a dependent point on a surface or related to it. There are four ways to specify the displacement of the point’s location relative to the UV position:

• OnObject - the point is actually on the surface of the object.

• Offset - the point is offset some distance (specified in object space) from the surface of the object.

• Normal - the point is offset along the direction of the surface’s normal. (Negative values move it opposite to the normal.)

• Tangent - the point is offset some U and/or V distance along the tangent from the surface. If the value is positive it's the tangent that heads in the direction of increasing parameter value; if negative it's the tangent that heads in the direction of decreasing parameter value.

Constructors

Any of the object's properties may be set via optional keyword arguments on the constructor.
