Good Day opengl people!
First of all i want to remember to all i m a very very beginner with 3D graphic.
I have a questio that i hope will be answered because i m really getting mad about a porblem.
I have a table of struct that describe all wath i need to draw polygons
(struct poligonnumber[max]{x,y,z})
and now, after being drawing that polygons,i would like make a step and render it smoother.
I know tha way is nurbs or mesh or bezier, or all the things above toghter but i would need a really small but complete example to how to code that.
We suppose i want to draw a nurbs surface and i have 100 vertex that i pre-calculate, now how can i interpolate the relative nurbs surface?
Please help me, i really enjoy programming and that would make me happy!
if any body feel like to write a little example using gl, glu and glut libraries.... thanks to all people.......I hope in next time i will be able too to help you !
See next time and excuse me for my wonderfull english!!!!

Nurbs can be drawn using the glu utilities (as can patches etc.). Check out the quadric patch example on the NEHE developer site.
