Woolly November 30th, 2009
Patrick Stein

Woolly is my Lisp GUI project. It is based upon Sheeple and uses CL-OpenGL for display and ZPB-TTF for font-parsing.


Here is a shot of the test program as of 2009-11-29. It shows buttons labelled Red and Green, a label, and a subwindow which contains another subwindow and a Quit button.


Here is the same test program with the top-level subwindow rolled up and dragged over a bit.



Currently, Woolly isn’t far enough along to be really useful. As such, I haven’t yet made a tarball release of it. That is coming soon though.

Woolly Application Underway December 14th, 2009

I started building an application on top my Sheeple/CL-OpenGL library Woolly. I coach a volleyball team. I often sit down with a piece of paper and try to determine new serve-receive and defensive positions for my team. This is quite tedious because I can’t just move the players around on the page. Additionall, I have […]

Rendering Text in CL-OpenGL with ZPB-TTF December 9th, 2009
Patrick Stein

I promised in an earlier post that I would share my code for rendering anti-aliased text in CL-OpenGL using ZPB-TTF to load the fonts. Overview I use a three step process to render a string. First, I render the outline of the string using anti-alised lines. Then, I render the string as solid polygons into […]

Cross-Platform Development November 25th, 2009
Patrick Stein

In preparation for the upcoming TC Lispers meeting, I was testing my Sheeple-based CL-OpenGL GUI code on all of the different systems that I use. This was important because part of my goal in starting from bare-bones OpenGL was to make something that was pretty easy to port. The OpenGL libraries are the only non-Lisp […]
