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.

The Orb: a parametric trackball with BTU mounted ball and keyboard switches for buttons
But I doubt any of this will ever run on the GPU... Multi-threading on the other hand, is already implemented and it works on the Gamma side, but I had to switch it off by default because CGAL doesn't seem to be there yet (see here for more). It does mostly work though, at least for the polyhedral operation which is what matters, although it may not be the great speed-up you expect it to be.

Nanite-like LODs experiments
1) I used meshoptimizer to simplify meshes and building meshlets. But to combine these meshlets (for more efficient simplifying) I built a graph with weights and partition it. In this weight some metrics are included: the shared border length of a pair of meshlets, their facing direction and other similar metrics. The next step is to simplify these groups of meshlets (fixate borders for each of them and simplify meshlets within the group). So, you can make dependencies of newly generated meshlets on the initial ones.

Will the same texture used in many gltfs be duplicated in memory?
Here are some amazing tools for compressing GLTFs: https://github.com/zeux/meshoptimizer/blob/master/gltf/README.md

Maximum size of scene or a project in THREE.JS
I've also had good results with this tool: https://github.com/zeux/meshoptimizer/blob/master/gltf/README.md and kt2tdecoder + meshopt_decoder

[Part 7] Update of my Vulkan renderer: LODs, Multiple different meshes, Memory Allocator, Render architecture and more
Implemented Mesh LOD system. LOD selection is done completely on GPU. I generate LODs using meshoptimizer.

Given a mesh without indices, how I generate indices for that mesh and remove the duplicate vertices?
Maybe Meshoptimizer can be useful?
-
[Part 4] Update of my Vulkan toy renderer: Mesh Shader Pipeline, Reversed-Z Depth Buffer, SPIRV-Reflect and many more
Added NVidia mesh shader pipeline support, with old pipeline still supported on top. Meshlets are generated using meshoptimizer.

Algoritm to simplify geometric data similar to texture bitmapping
I've used the "Simplification" operation of meshoptimizer to simplify 3D model geometry: https://github.com/zeux/meshoptimizer

help implementing LOD edge collapse algorithm
I call meshopt_simplify(). It uses a quadric error metric based mesh simplification of some sort. I haven't really looked into the details of how it works, but the code (with some comments referencing papers) can be found here: https://github.com/zeux/meshoptimizer/blob/master/src/simplifier.cpp
