Custom Game Engine framework

I the quest for a new project, I have decided to program a Doom game. When I explored the several options in Rust to write OpenGL or Vulkan bindings, I was slightly disappointed. I though it would a great idea to try and write a custom game engine. Since it is quite a challenging piece of work, I limited myself to a CPU engine (no hardware acceleration).

• Display any number of 3D polygons on a 2D buffer of pixels
• Each polygon can be associated a texture
• Pixel color is determined using the closest's polygon texture
• Binary space partitioning is implemented to determine which polygon it is.
