[cl-opengl-devel] cl-opengl on Windows
by Gilbert Wong 18 Dec '06

18 Dec '06

Hello, sorry if this isnt the right place for these issues since i'm fairly a novice to lisp. I am currently playing around with sbcl 9.17 on Windows and am having problems compiling cl-opengl. It seems that it has trouble finding all the gl functions, specifically anything above gl 1.1. Has this been adressed? Is there an easy way to utilize something like wglGetProc to address this problem? -- gilbert

[cl-opengl-devel] Depth issues with the darcs version
by Charlie Burrows 20 Oct '06

20 Oct '06

Hi, As I said I've just upgraded to the latest version of cl-opengl and now I'm having some issues. I'm upgrading from Frank Buss' April snapshot. The latest version seems to have some depth issues (or maybe it's just me!); when I draw a smooth shaded rotating cube (nehe6) the sides overlap the center and sometimes the backface is at the front. There is another demo that is a triangle and a square that rotate, I modified them so that they were overlapping but the one that's drawn last is always completely in front of the others. It's like I'm using the painters' algorithm. These demos looked fine before and I can't see anything that I'm doing that the gears demo isn't doing or visa-versa (except for display lists). Any suggestions? Cheers, Charlie
