virtual bool GD_PrimNURBCurve::evaluateBreakSegm ( int  ustartidx,

Evaluate the face between breakpoints by taking a start/stop index in the valid domain and a level of detail representing number of points to be interpolated between every two breakpoints. The method always interpolates the encountered breakpoints (aka "edit points"). This returns true if successful, else false.
