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.

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

School project
MeshLab is free software that can work with point clouds. I've only used data in .ply format so I'm not sure what other formats are supported.

I had facial surgery and 3D printed before and after CT scans.
I used a program called Radiant to convert to STL and then did some small edits using Meshlab.

How to reduce the vertices of this LiDAR scan without ruining the model?
The best open source way I have found is using MeshLab

Best way to work with point cloud files?
You could start by importing the point cloud model into a software with native support for the file format. Some open source examples are Meshroom (https://alicevision.org) or Meshlab (https://www.meshlab.net). There are other softwares from companies like Autodesk that might be more intuitive but you'd need licenses to use them. Rhino and Blender can handle the file formats but might struggle depending on the size and complexity.
