i wrote this but the texture won t draw, what can i do, please?

You need to provide texture coordinates before each vertex with gltexcoord2d...

Oups sorry to had disturb you for a so dumb question, the response was just in front of my eyes, but thanks anyway

No problem. All those GL functions GL_LOOK_ALIKE_AFTER_AWHILE.

:p
