🎂 Birthday Gift for Kivy Devs: Kivy-GLSL Guide

[Yassine Ouchen]

Hi Kivy Developers,

Today's my birthday 🎉, and I'm excited to share a gift with this amazing community:

Shaders in Kivy: From Basics to 3D with GLSL
A hands-on guide with practical examples, covering:

• 2D animations (gradients, touch interactions, ...)

• 3D rendering (ray-marched sphere, transform-based cube)

• Full integration with Kivy’sRenderContext

🔗 GitHub Guide: https://github.com/OuchenTech/Shaders-in-Kivy/blob/main/GUIDE.md

This guide is the Fruit of my deep dive into GLSL over the past few months, driven by two exciting goals:

1. Developing a protein visualizer - Creating interactive 3D PDB file rendering in Kivy (currently in progress)

2. Enhancing my game development - Building lightweight, GPU-accelerated effects for Kivy games

Through this journey, I've documented everything I learned about combining GLSL's power with Kivy's flexibility.

Perfect for developers who want to:
✓ Add GPU-powered effects to your apps
✓ Understand Kivy+GLSL integration
✓ Experiment with 3D in Kivy

I’d love your feedback or ideas on how to make this guide better!

Cheers,
OuchenTech

Thanks for sharing and happy birthday!

FYI The link near the top of the message is not pointing to the correct repository, here it is: https://github.com/OuchenTech/Shaders-in-Kivy/blob/main/GUIDE.md

For those interested in learning more about GLSL here are two additional resources:

https://thebookofshaders.com/ - Intro and background on shaders.  Interesting interactive book.

https://www.shadertoy.com/ - lots of examples of shaders.  Changes required to run with kivy.

Thanks. Happy Birthday.

There are also a number of examples in the kivy-examples directory. If you installed the kivy-examples, you will find them in your venv. You can also find them on the kivy github: https://github.com/kivy/kivy/tree/master/examples

• .venv/share/kivy-examples/demo/shadereditor - an interactive shader editor
• .venv/share/kivy-examples/3Drendering - Display of a 3d model
• .venv/share/kivy-examples/shader - Some visual effects using shaders
• .venv/share/kivy-examples/widgets/effectwidget2.py - effect widget example with shader
