Not exactly D3D vs OGL, but...

I am relatively new to 3D programming. It happened so that I learned Direct3D instead of OpenGL (I didn''t know about NeHe when I started, and DXSDK''s tutorials were the best source I had). Now as I read D3D vs OGL forums, I get the feeling that I should at least try doing GL instead of D3D. But: If OpenGL is so much better, as people say, why are (many?) games built using Direct3D? Why do many commercial graphics software (games and not games) use Direct3D? Also, as I was running a demo from this forum with debug Direct3D runtime on my WinXP, the debug spew was labeled ''Direct3D8''. The program never loaded d3d.dll or d3d8.dll, but it did load ddraw.dll and (as debug output suggests) created DirectDraw surface, etc. So is OpenGL implemented using DirectDraw on Windows? If so, is it (theoretically) slower than Direct3D which does (I think) not rely on DirectDraw? Thank you for your insights into this.

> vertex buffers as opposed to glBegin

Vertex arrays, perhaps ?

And there is something very appealing in VAR as opposed to vertex buffers...

Compliment ... this is the correct answer , in my opinion ,to the endless flame war ,opengl vs direct x.

the only point I do not agree with you is about the best choice for beginners and\or amateurs .
Personally I would suggest opengl , unless he\she is a beginner as graphic programmer but a windows \ c++ guru.
