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.
Open-Source Vulkan C++ API

what math is required?
It might be useful to maybe look at the Vulkan.hpp examples since you can do the same in about 200 lines of code. https://github.com/KhronosGroup/Vulkan-Hpp/blob/main/samples/15_DrawCube/15_DrawCube.cpp
- Vulkan-Hpp now provides C++20 module interface file

How do you guys organize everything?
Wow that library looks amazing, I'll definitely be using it. Bonus that it's official from the Khronos Group. https://github.com/KhronosGroup/Vulkan-Hpp

An idea to ease wrapping C libraries in C++.
Even auto-generated c++ wrappers like vulkan-hpp require lots of manual maintenance.

Anybody know why V-EZ has not been updated in 5 years?
Ultimately I went with vulkan.hpp RAII bindings, even though that way also has some learning curve and I couldn't find any documentation other than the RAII programming guide. It's great for getting started, but could use a complementary auto-generated API doc. There are also decent programming samples, which really suck for getting started, but otherwise do a good job of presenting concepts they focus on. Putting the available resources together I was able to get a project going in two weekends.

Using enum classes as bitmasks
This is exactly how the official Vulkan C++ API, Vulkan-Hpp does it. For the precise example mentioned in the blog post:

Or the vulkan.hpp RAII samples would be a good place?
-
What's the most hilarious use of operator overloading you've seen?
For a real-life example: consider the vk::raii namespace of Vulkan-Hpp, where the developers have posted examples. The vk::raii::su namespace has a bunch of free functions that one might think are associated with a Vulkan instance/object (in fact, the Vulkan Tutorial does implement them as member functions), but they are much nicer when used as pure functions. It keeps the class/struct definition itself nice and clean.

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.

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.
