Hi there, Throughout today I've spent a great deal of time trying to enable multisampling in my application. However, much to my disappointment, I have not been able to do so (using my own application, or Nehe's Lesson 46 demo on full screen anti-aliasing). Basically my calls to find out get extension string for WGL_ARB_multisample, GL_ARB_multisample (think you need 9500+ for this), and other varients all returned values saying I could not use it. As a note, when I would then try to use:
	glGetIntegerv(WGL_SAMPLE_BUFFERS_ARB, &buf);
	printf("Number of sample buffers is %d\n", buf);
	glGetIntegerv(WGL_SAMPLES_ARB, &sbuf);
	printf("Number of samples is %d\n", sbuf);
The output I would see is: "Number of sample buffers is -858993460" "Number of samples is -858993460" Following this, I went into the Display settings for my card and forced the SMOOTHVISION to be set to my desired settings (4x). I then closed it and attempted to run my applications again, though multisampling still could not be enabled. I then looked around the net and found that my card (ATI Radeon 9000 using the Omega 2.4.96c Drivers) supported something refered to as supersampling but not multisampling (what the differences are, I'm not sure since I have not been able to find a piece of documentation that notes thier differences). I then search wglext.h, wglati.h, glati.h, and other libraries but was able to find no mention of supersampling. Because of this, I was wondering if anyone possibly knows what the differences are (or provide a link to some documentation), or even better, a possible solution to my problem. Thank you very much.[/source] [edited by - Sundance on January 11, 2004 11:45:50 PM]
