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.

I made a proof of concept 2.5d engine (Download in comments)
This uses the "Voxel Space algorithm" used in 1992s Comanche to get a faux 3d terrain. Based on the code from here with some optimizations to get a reasonable FPS.

Voxel Space Engine: Comanche Terrain Rendering
Reminds me of this: https://github.com/s-macke/VoxelSpace
Another implementation to play around with here; this one's not DOS but web based though.

The Genius of Binary Space Partitioning in Doom
I'm reminded of the render algorithm in Comanche, the 1992 video game [0]. I find it remarkably ingenious, and it certainly felt incredible at the time.

Infinite procedural terrain generated in Godot3D
The heightmap I've been manipulating may also be familiar to you, but not for the same reason, because it's terrain data of Mt. Fuji. I'm thinking of heightmap files instead of infinite noise, mixing the perks of ray-based rendering insights with a manageable early-'90s-style aesthetic and conventional level design. An erosion simulation could be preprocessed with a seamless OOB margin in that context too.

Voxel space and WGPU troubles
I wrote a voxel space implementation in Rust some time ago using SFML, and now am trying to move it to WGPU in order to learn how GPUs work better and perhaps solve a horizontal lines glitch I've got.

Voxel rendering using pixel columns.
Recently, I’ve been getting into voxel rendering, and I’ve been thinking of a way of extending the voxel space algorithm. https://github.com/s-macke/VoxelSpace

The Genius of Binary Space Partitioning in Doom
> None of these techniques is relevant anymore given that all the hardware has Z buffers
Not true if you consider transparent objects. Rendering with order-independent transparency is still a hot topic without a clearly winning solution on GPU.
Web browsers have lots of semi-transparent rectangles, which can be transformed under "preserve3d" context. This is a classic case of effective BSP that is actual. (background: implementing BSP in WebRender a few years ago).
