-- set up performance measuring tests
-- Meshes (look into how meshlets are integrated) with their own BVH
-- More efficient buffer writing (everything is currently copied to storage buffers every frame)
-- BVH for the scene
-- look into multi-pass techniques and compute shader performance
-- properly blend between rasterized and raytraced graphics
-- support light sources
-- more material features
-- denoising
-- importance sampling

+
+## What it currently does
+
+- Blends Bevy rasterized output with raytraced data based on depth (is inaccurate and has room for optimization)
+- Supports some basic properties of the bevy StandardMaterial for spheres
+- Builds a BVH for the scene
