Graphics / sdl user but I'll switch

I'd say best way to test would be "trial & error". You could use any of the minimal examples or a short test program to test this.

Thanks Mario.  I will try an SFML sample.  Can you recommend one to try?

I program mostly in Visual C++ 2010 now, but also Linux G++ or whatever.

Ok, here's what I have learned about the stencil buffer HD3000 issue...

A Windows OpenGL app (using CreateWindowEx) works when the Intel HD3000 3D option is set to "Default Settings" or "Application Settings", or any setting.

An SDL app only works with HD3000 3D option set to "Enable Software Processing".

Also, with "Enable Software Processing", both apps run at about half speed.

Questions:

What parameter options should I try in SDL to get it to work at Intel "Default Settings"?

Will SFML require "Enable Software Processing" also?

Thanks.

Yes, I solved the problem and it was a driver issue, not SDL.  Intel driver installation reset a parameter, and you must set it to "Software" in the 3D section of their HD3000 setup utility.

>>What do you mean by software rendering?

I draw all pixels in the video buffer myself, then swap the page, and draw again.  Like in the old days.  Lots of clipping, poly-filling, z-buffer maintenance, etc.  Very fun.

Laurent, does SFML provide a video buffer address to OpenGL so it can draw?  If so, then I could use that address to do my own drawing.  Do you think yes or no?  Is there an explicit page-flipping function in SFML that I would call?

Anyway, thanks for the help guys!

hello,

I'm here because I just updated my Intel HD2000/HD3000 graphics drivers, and SDL stencil buffer stopped working.  No shadows.

Are there any known issues with SFML and HD2000 graphics drivers on Windows 7, or a 64-bit OS?

One other question, can SFML be used to do software rendering?  I currently use SDL to do that on Windows and Linux.

Thanks.
