Simple raytracer with refractions and reflections, using both SDF raymarching and regular raycasting using O(1) formulas.
There will be more in the future.
General trait that all objects must implement regardless of how they will be rendered.
Trait for objects that will be rendered by raymarching. Requires the declaration of only sdf function, which defines the object's Signed distance function.
Trait for objects that will be rendered by normal raycasting using a simple formula. Requires the declaration of only find_intersection function, which determines the intersection point of the ray and the object.
Unlike the previous two trait, this one does not require Object implementation. The only required method is build_objects which returns a list of tracing objects, for example, a list of the object's polygons.
Helper trait for meta-objects with some Object methods. With the help of it, for example, constructed polygons can conveniently refer to the object that constructed them in color and material getters.
This is not a completed project, so the test scenes for rendering are still set in main.rs.
