Shapes

  • Sphere
  • (Infinite) Plane
  • (Infinite) Cylinder
  • Capsule
  • Triangle

Materials

No material-related stuffs, at all.

No textures, no normal mappings. Only single color per an object.

Imports

You cannot import 3D models from other files. You have to model everything within this crate, using basic shapes.

Exports

It uses image as its backend. That means it can only export its result to image files.

Optimizations

It only uses CPUs, because I don't know how to handle GPUs.

It takes full advantage of multicores, thanks to rayon

  • Global Illumination

    Global Illumination

    When a ray from camera hits an object, more rays are shot from the position. Directions of the new rays are determined by the normal vector of the position. (where inner_product(new_ray_direction, normal_vector) is bigger than certain value.)

    Add another stage in the pipeline after collisions_with_objects. Merge it with colors_and_distances later.

    When calculating GI, don't use lights_for_soft_shadows. Use self.lights instead.

    Remove all the previous code for GI.
