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.

Confused in terms of where to start with framework/technology etc. Need help picking between learning ShaderToy v/s OpenGL v/s WebGL
If you want to go all the way, https://learnopengl.com/ is a favorite around here. You could build a glTF viewer from scratch starting from that tutorial and https://github.com/jkuhlmann/cgltf and eventually building towards https://google.github.io/filament/Filament.html or whatever wacky artsy direction you like.

Best courses for learning graphics programming?
Use https://github.com/jkuhlmann/cgltf to parse the files. https://github.com/ocornut/imgui for your UI. Maybe https://www.libsdl.org/ just to set up a window, handle mouse clicks and initialize the GL context in that window.

I was learning OpenGL and, I needed a suggestion : Which are the best 3D model formats (In terms of ease of loading)
Use glTF and https://github.com/jkuhlmann/cgltf Or, looks like you are using C#, so https://github.com/vpenades/SharpGLTF

What is the best FBX loader for modern OpenGL? (C++)
Do you really have to use fbx? An open format like gltf is better supported, and there are bazillions loaders(I use cgltf without any issues, which is also used by raylib, Unigine and bgfx). It's also a perfect fit for OpenGL.

PortableGL: An implementation of OpenGL 3.x-ish in clean C
I recently discovered this pattern in cgltf (https://github.com/jkuhlmann/cgltf), and I agree, it makes deployment so much nicer.
-
Good entry-level model format with animation
Use https://github.com/jkuhlmann/cgltf It’s the most popular loader.
- Any opensource lib for loading gitf files? Something lightweight if possible
-
Is it worth writing a software raytracer before going into hardware accelerated RTX?
It's easy to generate a BVH for a generated triangle set (like a fractal pyramid or a dense cube). But, quickly generating a high quality BVH for a loaded model requires some research. Use https://github.com/jkuhlmann/cgltf to load models.

How to become a tools/graphics/engine programmer
Write a simple glTF viewer in OpenGL. This is a throw-away warm-up. So, don't fret over the code. Don't do anything complicated. Shoot for a simple, forward renderer for a simple, animated character with trivial Phong lighting, diffuse map, normal map and a basic directional shadow map. Use OpenGL ES 3.0/GL 4.3 API with no crazy features. Don't worry about performance. Use https://github.com/jkuhlmann/cgltf to load the files. KTX is a great container for textures.

Using Jolt with flecs & Dear ImGui: Game Physics Introspection
Nuklear is an alternative Immediate GUI, also written in C.

LÖVE: a framework to make 2D games in Lua
> And for the right project, especially those where a predefined engine structure does not not fit, it can still be the most productive choice.
Right on. While interning at an oil refinery, I developed an application in LÖVE that processes and displays data from spectrometers. In hindsight it may not have been the wisest choice, but hand rolling all the GUI elements I couldnt force out of the Nuklear[0] bindings for LÖVE gave me a strange sense of satisfaction.

Looking for a Julia gui framework with a demo like EGUI
No, Nuklear has been updated 2 days ago.

Is there no simple GUI library for pure C?
I think good option would be nuklear it is a single header lib

ImGui or text rendering libraries
For GUI, there are lots, most well-known of course being Dear Imgui, for which people have made auto-generated C bindings. Another mature but a lot simpler option is Nuklear, as others have mentioned. Even more minimalistic (it's just 1KLOC) is microui. There are a lot more, just google "imgui library c".
There's Nuklear.
