# Voxel Raytracer

A voxel is like a 3d pixel used in many fields and applications. It can also make for some interesting 3D art.

## TODO

- support changing of camera angle and position

- support different voxel materials

- support shadows and lights (emissive materials)

- support many models in the same scene

- avoid unnecessary voxel marching by using AABB collisions check with the voxel model

- try using compute shaders rather than fragment shaders, it could be beneficial though I need to research why

- render using multiple passes rather than a single pass to support lower-end GPUs, and generally allow for more samples per pixel

- voxel editor !? (a bit of a stretch)
