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.

How do I get OpenGL working in a c++ vscode project?
Here you can find my toy engine, the CMakeLists may be a bit of a mess though, I am kind of a beginner when it comes to using CMake, but the idea is to let CMake generate the Visual Studio files and folders architectures on its own, it's a very powerful tool, very useful if you ever want to go cross-platform.

Created wavefront obj file loader for triangles only. Sadly this is my last upload for a while. I can't work for a week or a month. Anyway keep on creating.
What do you mean by "triangles only" ? Triangulating arbitrarily sized polygons in wavefront formats is pretty simple, here is how I do it (I have to redo this code as it's a mess but you get the idea)

If you are interrested, you can find my code here, be warned though : it's a mess 😅

Is there a library that rotates/translates your camera from mouse input?
Here is how to compute rotation from Yaw Pitch Roll once you got that you can simply use mouse X, Y as Yaw, Pitch

Making a better 2D asset pipeline
As an aside, crunch compression is a bit of a red herring here. While it does reduce the size on disk, it needs to be expanded back to regular DXT when it's first displayed, so it won't solve our memory issues by itself.

The Quite OK Image File Format Specification: A Single Page PDF
Have you considered compressed texture formats? Fixed compression ratio (usually 1 byte per pixel), arbitrary random access, decompress the pixels you need on the fly. Can be further compressed for efficient storage closer to JPEG ratios with https://github.com/BinomialLLC/crunch.

glTexStorage2D and compressed textures
After spending some time trying several libraries, I settled with FasTC for now, but it seems to only be able to manage 32 bits RGBA image formats... I am looking into Crunch2 which is basically Crunch with modern CMake.
What are some alternatives?
