raylang-rust

Simple raytracer for exploring programming languages. Rust edition.

Based on David Breen's CS636 Class assignments and my own previous Haskell implementation cs636-raytracer.

Why?

For fun. To learn new languages, and how usable they are for a heavily computational program. Rust in this case.

Running Examples

To run the examples, you need some .smf model files in the models/ directory. The example model files are originally from https://www.cs.drexel.edu/~deb39/Classes/CS586/Models/

Use the following command to download them all:

wget -r -np -nd -A smf https://www.cs.drexel.edu/~deb39/Classes/CS586/Models/

Building and Running

cargo build --release
cargo run scenes/scene0.json --release

Running without --release will take significantly longer due to the lack of optimization.

Output image will be written to the file specified in the scene0.json file.

Wrote file "scene0.png"

As of 0.2.0, scenes can also be written in Python by constructing a data structure similar to the json input and passing it to a render function. This uses the scene data structure, ray tracer C library, and Python utility functions as a small embedded domain-specific language (EDSL) and has the advantage of being able to generate parts of the scene programmatically.

python scenes/scene1.py

Versions and Status

Tagged versions correspond to assignments. For example, 0.1.0 implements the requirements for assignment 1. master may contain a partially completed next version at any time.

The current version is: 0.3.0
