soft-raycasting-demo

A simple (and slightly messy) software ray casting renderer, written in Rust. It uses rust_minifb to create a window within which to render and capture input. Here's some of it's features:

• A cell based layout system.
• Affine texture mapped walls, floors and ceilings, with each cell able to have unique textures.
• A simple font renderer, used for an FPS display.
• Primitive BMP parsing for fonts and textures.
• Simple lighting effect based on the alignment of a cell's walls.
• Sprite rendering.
• Adjustable camera height.
• A 2D Z-buffer.
• Thin wall support, including transparency.
• Per-tile fog (but not volumetric).
