Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

High Performance Voxel Engine (2021)
It's just normal old raycasting through a voxel grid a la Amanatides and Woo: http://www.cse.yorku.ca/~amana/research/grid.pdf https://github.com/cgyurgyik/fast-voxel-traversal-algorithm/...
Casting the rays from the camera will be nice and coherent, plus you probably get much better and easier shadowing using ray casts compared to shadow maps.

Guidance for small voxel renderer
The I changed to the "fast voxel traversal algorithm" which makes sure to hit every voxel and is a bit faster too. See: https://github.com/cgyurgyik/fast-voxel-traversal-algorithm/blob/master/overview/FastVoxelTraversalOverview.md

Voxel engine I've been working on
t's a raymarcher using the Fast Voxel Traversal algorithm by John Amanatides and Andrew Woo. The voxels are stored in an octree (actually a 3D texture with mipmaps), and to do LoD I simply stop at higher levels in the octree.
- Any good resouces on Implementing Raycasting Rendering that ya'll can share?
