Public function Point(const U, V: Single; const OutputNormal: PVector3 = nil): TVector3;

Get the position of a point on the surface.

The returned position is in the local transformation space of this shape. This method is guaranteed to work the same, regardless if this node is part of any TX3DRootNode and TCastleSceneCore or not.

Parameters
U
First parameter of the parametric surface, in [0..1] range.
V
Second parameter of the parametric surface, in [0..1] range.
OutputNormal
Optional. If non-nil, will be set to the normal, that is, normalized direction in 3D that is orthogonal to the surface at this point.
