So if you don't use glMap, what do you do? Do the calculations?
Do you think NURBS is more reliable?

Hi Relic,
Thanks for your answer,
My mean is to find the XYZ coordinates of the point I just drawn.
If glEval doesn't update this data is there any other way to get this information(without...

I did the same test and it doesn't work...
So I found another solution with line strips and now I have another problem to find the real coordinates of the control points...
Anyway if you find a...

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;...
