Anyone here familiar with 3D graphics programming?

[Tanshaydar]

I took a Computer Graphics course and we used OpenGL 3.3
In my opinion OpenGL should be more viable choice for every 3D and many 2D applications, but well, DirectX is getting better and better, so it depends on the team which one to use.

HPL uses OpenGL 2.1 yeah. As far as I know HPL3 will support DX 10/11 and OpenGL for backward compatibility.
