[Raycasting] [Sprites] [Tiled backgrounds] [Voxels]

This page contains source code demonstrating techniques often used in game programming.

Raycasting example

A example program to demonstrate the process of ray-casting.
Note: This isn't the fastest, nor the best way to do ray-casting. These routines have intentionally been slowed down to improve readability.

Simple sprite routines

Sample source code on using sprites. This is a small demonstration which makes two sprites bounce around the screen.

Voxel landscapes

Source code to display voxel landscapes as used in Comanche: Maximum Overkill .
Note: Again, this isn't the fastest, nor the best way to do voxels. These routines have intentionally been slowed down to improve readability.
