Need some advice for OpenGL

[LP]

Now here's my question: is there a tutorial (best for Object Pascal) for building an OpenGL 2D engine which does not use deprecated stuff?

Yes. Clicky.

Yes. Clicky.

Okay, I will have a look into that. Is there a GLEW.pas available??

I heard that a lot of functions will be deprecated in OpenGL 4.x, BUT most of the hardware still do not support OpenGL 4.

I recommend you to use FreeGLUT, it will give you a good cross-platform support. I'm using it on my game engine.
