Raytracer

A multithreaded CPU-driven raytracer using pathtracing.

To run:

cargo run --profile release # 4 samples per pixel
cargo run --profile release -- <samples_per_pixel>

To configure the renderer, modify src/config.rs:

pub enum Target {
    Image,
    Window,
}

// The width of the image or window
pub const WIDTH: usize = 600;
// The height of the image or window
pub const HEIGHT: usize = 450;
// Use multiple-importance sampling or not.
pub const USE_MIS: bool = true;
// Render to an image or a file
pub const RENDER_TO: Target = Target::Window;
// If rendering to an PPM image, the path for the output PPM file
pub const PPM_FILE: &str = if USE_MIS {
    "with_mis.ppm"
} else {
    "without_mis.ppm"
};
