Engine

A super basic graphics engine written completely from scratch that can render .obj and .mtl files WITH texture mapping. I've been working on this as both my first rust project and a way to kill time at work.

Run

Usage: engine [OPTIONS] --filename <FILENAME>

Options:
  -f, --filename <FILENAME>
  -n, --normals              flip all normals
  -h, --help                 Print help
  -V, --version              Print version

RUST_LOG=info cargo run --release -- --filename objects/cottage_obj.obj

You can replace objects/cottage_obj.obj with any .obj file.

Polygons:

1. ff any degree >= 3 are suppored
2. without a material will be rendered DIM
3. with a material will use the corresponding .mtl definition.

Check out my blog post that talks a bit about the foundations of computer graphics.

.mtl file paths are RELATIVE to their .obj files.
