[@basstabs] published a tutorial which explains how to write a

line of sight algorithm for 2D games in Rust without using trigonometry or

square roots. It includes vector diagrams and typeset math to explain the ideas

behind each stage of the algorithm, source code for each step, tests to verify

accuracy of the methods, and suggestions for further improvements.

Additionally, the

[repository](https://github.com/basstabs/2d-line-of-sight) contains benchmarks

and a sample application written in [ggez](https://crates.io/crates/ggez).
