Texture mapping code can be found in TextureMapping.js. THREE.js handles several WebGL texture initialization functions. For my texture mapping implementation, I created shaders, included in TextureMapping.js. The texture mapper contains all of the images that will be used in the program.
Graphics for the brick and chainsaw textures were created by myself. The chainsaws were inspired by those seen in Super Meat Boy. The background images were modified from Canabalt's backgrounds, created by Adam Saltsman. Meat Boy's face was created by Edmund McMillen for Super Meat Boy.
