Hi guys,
I'm drawing a pseudo-nurbs with line strips and draw the points and I want to draw the control vectors :
glMap2f( GL_MAP2_VERTEX_3,...)
// draw strips
// then draw points
for ( w=0; w<WidNbr; w++ )
for ( h=0; h<HgtNbr; h++ )
{
glBegin( GL_POINTS );
glEvalCoord2f( [x],[y] );
glEnd();
}
and I try to get back the real position of each point.
I have tried with glGetFloatv and glGetMapfv but I can't get it.

Any idea?
Thanks
Pierre
