NurbsCurvePointListSetPoint Method (Int32, Double, Double, Double, Double) |
Sets a homogeneous control point at the given index, where the 4-D representation is (x, y, z, w).
The world 3-D, or Euclidean, representation is (x/w, y/w, z/w).

Remarks
For expert use only. If you do not understand homogeneous coordinates, then
use an override that accepts world 3-D, or Euclidean, coordinates as input.
