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.

Ask HN: What is your new year's resolution?
Sort of.
1. I want to start with working through applying shaders to a 3d scene using the Panda3d library (https://github.com/panda3d/panda3d) . This repo covers that: https://github.com/lettier/3d-game-shaders-for-beginners.
2. Create a simple, custom, graphics-only (no collisions / physics) game engine using Entt (https://github.com/skypjack/entt) and Panda3d. The engine would rely mostly on simple inputs, like mouse clicks, and 3d graphics.
3. Configure clangd to warn on features outside C++11 then refactor both projects (1 & 2)
4. Run experiments on the game engine while working through the Vulkan book: https://raw.githubusercontent.com/Overv/VulkanTutorial/maste...

Game Engine From Scratch
Some tutorials I have looked at (well nor originally, as I learned the basics when we were still at DX9 :D): - https://lettier.github.io/3d-game-shaders-for-beginners/index.html
- Are there any resources on Post processing effects like Bloom HDR rendering tone mapping etc..

Thanks! What feature would you add next? I've been thinking of implementing some of the shaders here

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 specifically want to learn shader programming then https://shadered.org/ is a lot more practical than Shadertoy.

How to display a 2D array every frame
https://github.com/dfranx/SHADERed (useful tool for debugging shader code, has a bit more functionality than doing it in Godot directly)

I am developing a GLSL shader editor and I hope you like it!
Can you tell us how do you compare to https://shadered.org/ ?
https://shadered.org/ spent much time on basic editor features like Intellisense and now it seems to be dead. The time would have been better spent fixing/improving the core features like the awesome debugger. Only very late they added a (basic) VSCode integration.

Winning shaders at Revision 2022 shader showdown
Hi corysama, thankx for the comment, there is some truth to that yes for sure. As in, in games you writes more vertex / pixel or "surface" shader and then geom, compute. But I have to somehow disagree in terms of lighting. Sure this is raymarching so geometry is procedurally made in the shader, whereas in game shader it is passed with polygonal 3d model. But the lighting / colour shading calculation are the same as with polygonal geometry (ndotL for diffuse pow(max(reflect(dot(-ld,no)... for specular, calculating normals on fly in shader, etc...) so in that respect it will help for game dev style of shaders. Also I would argue that a lot of animation technique and vfx technique in raymarching shaders are similar / useful / reusable with polygonal geometry, like yanimation based on clamping sin and doing easing etc. Therefore doing raymarching shaders is good for becoming vfx artist / technical artist I guess. You are right though to point out the difference, that's clear. Good shout about shadered.org as well. Cheers!
Most people in this area play in Shadertoy. But, if you are interested in shaders for games and stuff, https://shadered.org/ is a more appropriate playground.

Resources for someone who'd like to have fun with graphics programming without going through drudge work
It’s open-source if you gots some ideas to add https://github.com/dfranx/SHADERed
Maybe https://shadered.org/ would be a better workspace for you to get started rather than bootstrapping from int main() {}
