A raytracer in Rust. Compiles on Rust stable > 1.5.

Gallery
Gallery repository
Assets repository

Usage

Clone the project. --recursive clones most sample models and textures into the project directory as well.
```
 git clone --recursive https://github.com/gyng/rust-raytracer.git
```
Compile
```
 cargo build --release
```
Edit sample-config.json if you wish to render a scene besides the default, or if you wish to tweak the renderer parameters
Run the compiled program, passing the render configuration as an argument. If rendering a provided scene, run the binary in the project root so it can find the models and textures.
```
 ./main sample-config.json
```

or alternatively to compile and run in one single command

    cargo run --release sample-config.json

Useful commands

To update (assets) submodules only: git submodule foreach git pull
To convert frames into a video ffmpeg -i test%06d.ppm -b 2000k out.webm
Scenes are created in ./myscene/. To hook up a scene, add it to ./myscene/mod.rs and get_camera_and_scene(&SceneConfig) in main.rs.

Available Scenes

These should use 30deg fov for squares and 45deg fov for 16:9.

rust-raytracer's Issues

Cannot compile the project

Hi,

I have just cloned the project, went inside and ran the command from README:

cargo build --release

I get this:

error[E0642]: patterns aren't allowed in methods without bodies
   --> /home/radu/.cargo/registry/src/github.com-1ecc6299db9ec823/rustc-serialize-0.3.16/src/serialize.rs:145:45
    |
145 |                                             &f_name: &str,
    |                                             ^^^^^^^

My rust version:
rustc 1.27.1 (5f2b325f6 2018-07-07)

unknown scene: 'box'

Running a fresh, recursive checkout yields this error for me:

lunch-box. cargo run --release sample-config.json
     Running `target/release/rust-raytracer sample-config.json`
Job started at 1465205449...

unknown scene ``box''
error: Process didn't exit successfully: `target/release/rust-raytracer sample-config.json` (exit code: 1)

:(

compile / build error

I'm building on Ubuntu 14.04. When running cargo build --release, I get these errors
