Detailed Description

This class does basically the same as Builder3D except that it writes the data directly into a given stream without buffering the output data in a string stream.

Compared to file streams string streams are quite slow when writing data with more than a few hundred lines. Due to performance reasons the user should use a file stream in this case.

The number of control points must be numUControlPoints * numVControlPoints.

The order in u or v direction of the NURBS surface is implicitly given by number of elements in uKnots - numUControlPoints or number of elements in vKnots - numVControlPoints.
