Hi, I was running into some problems setting a uniform variable with UNIFORMF - I could give it a number, but for some reason it wasn't evaluating anything else passed to it, reporting "The value X is not of type REAL."
Anyway with some discussion on #lisp, stassats came up with a little patch that seems to work.
Here's my original effort that had problems: http://paste.lisp.org/display/88062
And the patch: diff -rN -u old-cl-opengl/gl/opengl.lisp new-cl-opengl/gl/opengl.lisp --- old-cl-opengl/gl/opengl.lisp 2009-10-02 08:37:02.397150466 +0400 +++ new-cl-opengl/gl/opengl.lisp 2009-10-02 08:37:02.454149983 +0400 @@ -633,11 +633,15 @@
