A raytracer built in Rust, following the Ray Tracing miniseries (Ray Tracing: In One Weekend + Ray Tracing: The Next Week)
Features Include:
- Multithreaded, though manually, no rayon :(
- Camera with depth of field
- Primitive objects: sphere, cubes, rectangles
- Lights
- BVH for acceleration
- Material shaders (diffuse, dielectric, metallic and constant volume)
- Textures for materials (constant, procedural and image)
- Transformations (translation and rotation)
Layout
src/render.rs has the main render function, which takes a scene and camera and creates the output
image by sampling rays. The scene is some Renderable trait object, where Renderable (defined in
src/model/) is a Hitable object and a Material (defined in src/shader). There is also a
bounding volume hierarchy in src/model/bvh.rs.
The Hitable defines how to determine ray intersection, and the Material defines how the ray
interacts with the Renderable objects surface.
