I have two questions. First when I do movement with svgalib, I get some flickering only at the top of the screen. I am using vgagl and porting it to standard vga and get the same result. And I already used similar code in vgagl. And this is basically a line that crawls down the screen. The only problem is that there is some weird flickering when it travels down the screen. Any ideas? I think this a graphics programming problem maybe not a svgalib problem. while(1) { for (j = 0; j < 240; j++) { __memset(doublebuf+(j*320), 0, 320); } // end of the for __memset(doublebuf+(320*20)+0, 128, 300); __memset(doublebuf+(320*10)+0, 64, 300); vga_waitretrace(); vga_copytoplanar256(doublebuf, 320, 0, (320 / 4),320, 240); GetFramesPerSecond(); frame_count++; } // end of the while Also, I was thinking, since svgalib has some x-windows code in it. is it possible to add the opengl support for hardware acceleration. I know this is an extra-extra feature. I figure if X-windows does it, svgalib should be able.
