I hope my topic will generate responses to help me here because I’m really really really stuck.
I created my site using a three dimension table to have a ground flare.
For this I used the opengl functions glmap and glEval.
My field is displayed perfectly.
However I would like now made collisions with the ground.
My problem is that the field is rounded and I’m only the tops of the control points of the curve.
While the ground is round.
I would like to know how I can retrieve the tangents to the curves or simply having all the control points between.
I would like to know how his is that I can not display bezier curves in opengl with an array dimen greater than [32,32,3] if I go over 32 then nothing appears .
Thank you soon to help me out of pity, because I can not see doing so was as straight lines while the field is a curve.
