Rust Boids

This is a 2D boid simulator written in Rust. 🕊

cargo run --release -- -c example-config.toml

Aims:

• Fast, CPU based simulation.
• Support as many boids as possible.
• Render at 60fps on commodity hardware.

This is achieved by using:

• Approximate "neighbour grid" data structure.
• Lookup table based FOV culling
• (In progress) Parameters that expose performance/accuracy tradeoffs to the user.

It also shows how the glutin, gl and cgmath crates can be used together to build a simulation. In particular, it demonstrates the boilerplate needed to do useful work with OpenGL.

A big list of things worth doing or looking into are listed in TODO.md.

Configuring

The simulation parameters can be set via a toml configuration file.

See example-config.toml for an explination of the different parameters.
