I believe things will look better if I sort that out. Hopefully, I can tackle that sometime this week for you. Right now, I keep recursing way below one-pixel limits.

Fonts look really nice on big sizes, but they are quite messy on small size (less that 15pt). It seems that AA is a bit too heavy, I wonder if you have any ideas on how to improve this.

I am currently making a new font backend for Sheeple based game engine - Until-it-dies, I wonder if I can use parts of your code and if I can, what kind of attribution do I need to provide (meaning what license are you distributing this code with). Thanks, Mikhail Hello!

Thats what i've been looking for a year :) Though, i have a problem porting it from glut to sdl. The outline-fonts work fine, but the filled ones don't work. It seems like the stencil buffer doesn't work in sdl. It's probably something simple, but i just can't work it out sice i'm not used to the stencil buffer. It's just as removing the ":stencil" from the default initargs in glut. Anyone has an idea how to fix this?? I've been looking for hours now, but just can't find any good stencil examples for sdl. Thank you! JonnyB Thank you you a lot for this!

In some code, I cheat with conditions. I don't know what the default window-close handlers in GLUT do off the top of my head. There is also some inited? state floating around in CL-GLUT. I believe if you remove cl-glut from ASDF's list of loaded packages then things fix themselves. I generally can't use Slime effectively for OpenGL work on my Mac. I have to look into it more. People at the TCLispers meeting were surprised that I hadn't gotten threaded SBCL working on my Mac, so it may well be me. There is no good way out of the GLUT main-loop AFAIK.

But I have this problem: Using slime in emacs 23, linux, I run test.lisp and it works ok. I then close the gl window, and slime still works. Then I rerun test.lisp and it doesn't work as it says that "Lisp connection closed unexpectedly: connection broken by remote peer". I have to reload slime, and re-eval the lisp files. Any ideas why this is happening and how to fix it? Thanks. Thanks for this post.

It would mean an external package dependency (zpb-ttf) that the current examples don't have though... If that's okay, I will make it go.
