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.

question about wasted index Buffer data
If you reuse the same index buffer as proposed then you won't be able to share vertices, which can be an important optimization. In my case I use a 323 cache of vert indices and just insert an index rather than a vertex if the vertex already exists and has the same material. I generate normals in the pixel shader to increase what can be shared, and then use a variant of Stan Melax's edge collapse polygon reduction algorithm to combine edges and reduce triangle count.

help implementing LOD edge collapse algorithm
You might want to take a look at Stan Melax's easy mesh simplification technique with edge collapse at http://www.melax.com/polychop (read the full article link) - I've ported the code so it runs cross platform on https://github.com/dougbinks/BunnyLOD

Mesh optimization algorithms
I use a variant of progressive meshing, but constrained to preserve edges, normals and ambient occulusion in Avoyd based on Stan Melax's work: https://github.com/dougbinks/BunnyLOD

Voxel Vendredi 81
My triangle reduction in Avoyd, loosely based on Stan Melax's progressive mesh approach checks that the vertex being removed is internal to a set of triangles by checking that the internal angles add up to roughly 2Pi. This also ensures only flat surfaces are reduced, although I also perform normal checks and that vertex ambient occlusion gradients are preserved.

100,000 subscriber celebration – Ask the Godot contributors anything!
Therefore, in terms of artist mindshare, Blender is the leading open source 3D creation program, but not the leading 3D creation program. I think Godot is already in a similar situation, and has been for a few years now. In comparison, most other open source game engines have focused on providing low-level functionality. These certainly fulfill a niche, but in my experience, most people want something that works at a higher level and comes with a built-in editor.

Simple light graphics library for c++?
Since you want something lightweight, I'll assume you mean the former. If that's the case, then checkout bgfx or Magnum. Magnum does include some extra features typically found in a graphics engine.

Best C++ libraries for 2D game development
You could try Magnum it wraps SDL and others, but you might find it maybe too low-level. It's certainly not Love2D.

Exceptions: Yes or No?
C++ is similar to C in that there are multiple "styles" of use that vary from project to project. Other, usually newer languages (C#, Python, Rust, etc) tend to have a stronger sense of what idioms should be used. Whereas, for instance, some C++ projects (like some GUI libraries and game/graphics engines) will partially/entirely replace the STL (and older ones may have been around before C++ had a standard library aside from C's), or forbid the use of certain C++ features (example).

> He has Vulkan support in here with a clearly marked file named Pipeline.cpp. The guy knows what a pipeline is...
There is a Vulkan API wrapper. However, there is no "Vk Renderer" -- no code seems to use the Vulkan parts of the code system, and the two projects seem unrelated.
> * Is this not a UBO interface?
There are ways of making a uniform buffer, however the examples don't cover them and the API doesn't adapt automatically. See how all of the setters assert if UBOs are enabled.

> * I don't see why you think there's limited support for multiple framebuffers...?
The code I do see is about binding/unbinding framebuffers in a stateful manner, e.g. AbstractFramebuffer::bind(), rather than supporting passes.
> None of your criticism seem well intentioned. It might behoove you to give people the benefit of the doubt and realize that you may be able to learn something from them, even if they're so clearly inferior to you.
To put it simply, I've taught enough graphics to know first-hand the kinds of misconceptions that OpenGL-styled APIs can cause, and I'm just a bit tired to see it continue. Admittedly I was a bit harsh, I don't mean any harm towards the author. There are just graphics APIs with interfaces I consider to be much better designed.
