The example shows a wonderful mixing of OpenGL with Qt native rendering. You can type in any phrase, the application will try […]

Rendering polygons, especially when we’re dealing with stroke, tends to be the most expensive rendering operation performed in vector graphics. I constructed a little test, which tests raw polygon rendering power of Qt and Cairo. For […]

hmmm.. re: Joys of Freedom, R.I.P Opie http://zecke.blogspot.com/2006/10/joys-of-freedom-rip-opie.html Life is like the tides and the ocean.. sometimes rushing in, and other times rushing out.
