STnl stands for Software Transform and Lighting. It's a simple software renderer / rasterizer that demonstrates the basic principles of a programmable GPU.
We use 4 threads to render each horizontal quarter of the screen in parallel, so this application runs best on systems with 4 or more CPU cores.
