Game Engine

A project for me to explore writing a game engine from scratch using an ECS design pattern. My game engine is written in Rust, compiles to WebAssembly and binds to a WebGL canvas. That means it runs in a browser.

Currently, it supports the following features:

• 3D meshes built from vertex normals
• Surface normals calculated for models
• Phong lighting model (ambient, diffuse, specular)
• Multiple directional and point lights
• Orthographic and perspective cameras
• Multiple cameras, rendered to portions of the view
• Dynamic generation of GLSL shaders
• Materials, or colors specified per vertex
• Scene graph that's optimised for lazy updates
• Game loop that's frame rate independent
• Keyboard input event handling

Usage

$ make setup
$ make build
$ make server

If you're not on a Mac, you'll need to install binaryen manually. There are a few more Makefile commands you might find useful (e.g. build-watch). For more examples, check out the wasm-bindgen documentation.
