A simple ray tracer written in rust. Feedback and contributions are very welcome.
nix develop
After that you can do cargo build, cargo run --release etc.
Currently needs rust version 1.65.0.
On Linux you may need to install these dependencies for the minifb
crate to work.
sudo apt install libxkbcommon-dev
cargo run --release -- --scene ../resources/scenes/three_balls.yml
cargo run --release -- --scene ../resources/scenes/emissive.yml
cargo run --release -- --scene ../resources/scenes/noise_and_textures.yml
cargo run --release -- --scene ../resources/scenes/clown.yml
cargo run --release -- --scene ../resources/scenes/cornell_box.yml
The application accepts the following arguments.
--config path to the config file.
--scene path to the scene file (only supports yml).
--image-action (png, show).
Png saves the resulting image to config image_output_dir.
Just running it without any arguments will use the default config and scene provided by this repository. Once the application starts it will present a crude preview image of the scene.
Note that command line got presidence over configuration. I suggest you check config.yml for some ways to configure it. There are more options available and if you want to check all I suggest you check config.rs.
WASD : Moves the camera in a currently crude way.
L-Mouse : Rotate the camera as you move the mouse.
R : Starts/Aborts rendering the image.
Q : Selects the object your mouse hovers over.
E : Removes selected object.
R-Mouse : Move selected object.
Arrow Up/Down : Move selected object towards/away from you.
Arrow Left/Right : Move selected object left/right.
Numpad +/- : Change camera FOV,
Numpad 8/2 : Change camera aperture,
Numpad 4/6 : Change camera focus distance,
As you start rendering the image it will replace preview image with a more refined one with the settings from the render block in your configuration file.
Once the image is done rendering it will go forward with the selected image action.
