Rustray

May 2013

A raytracing proof-of-concept in Rust

Requirements

• Rust-0.6 (incoming)

Compiling

$ rustc rustray.rc

It's usually worth compiling with '--opt-level 3'.

Quality Settings

Now raytracing parameters are hard-coded in consts.rs, just edit it and re-compile rustray again.

Demo

This might take some time even on the strong machine, so consider choosing more simple model or adjust quality settings.
