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:

Recommendations on how to start a small Vulkan project
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.

Immediate Mode GUI Programming
Immediate mode is a fuzzy concept, as witnessed by this writeup: https://github.com/ocornut/imgui/wiki/About-the-IMGUI-paradi...

Black Triangles
It's fun to see the evolution in e.g. these examples of image loading for Dear Imgui:
https://github.com/ocornut/imgui/wiki/Image-Loading-and-Disp...
DirectX9 will even load the image for you, DirectX11 okay we get a few more structures to fill out, DirectX12 is where it goes off the rails and we are filling out a bunch of UNKNOWN DONT_CARE JUST_DO_IT. Then of course Vulkan is the one that gets the big fat "this probably won't actually work for you" warning.
I understand whats happening, but you know sometimes I just want to display a fucking image.

Dear ImGui: Bloat-free Graphical User interface with minimal dependencies
ImGui is engine/GPU agnostic
Themeing isn't a just a retained mode thing, you can do wonders with immediate UIs, even thought (dear)ImGui doesn't provide much, you can still do wonders: https://github.com/ocornut/imgui/issues/707#issuecomment-362...

Where do I start to learn C++ for a game development
Bonus: If you want to make desktop app with UI, then this is another great C++ library and it's also simple to learn as well. https://github.com/ocornut/imgui.

GUI library for fast prototyping
AFAIK the Rust equivalent to C++'s Dear ImGui is egui.

Stretching myself thin with Dear ImGui projects
They use a Dear ImGui, a C++ GUI library.

PCSX2 Disables Wayland Support
Aside from bugs and driver issues, Wayland has some unfortunate design limitations. For example, Dear ImGui multi-viewports don't work because "Wayland doesn't let application read or write windows positions."
https://github.com/ocornut/imgui/wiki/Multi-Viewports
This is a feature available on Windows, macOS, and of course X11. Making choices like this means desktop Linux becomes even more of a weird island that nobody wants to support.
