A Jetpack Compose-based app to exhibit all the beautiful GLSL Fragment shaders I have ever written, where you can set them as Live Wallpaper.

🎨 Shader Showcase

Shader Showcase is a minimal Android app made with Jetpack Compose, to showcase all the beautiful OpenGL* based Fragment shaders I have written so far. You can set them as Live Wallpapers too.

(GLSurfaceView has been used here to render a simple Quad and the Shaders.)

*Minimum requirement is OpenGL 2.0.

Features

• List of included Shaders rendered in realtime
• A detail page to show more options regarding the Shader
• Set the Shader as Live Wallpaper
• UI palette of Detail Page components is computed dynamically using Androidx Palette API

shadershowcaseapp's Issues

need some help.

Hi, I learned a lot by studying this app.
I just wanted to thank you for making this app and also ask for a little help.
Can you explain how we can use one or multiple textures inside an application. I just can't get my head around how we can push the data of bitmap into a shader.
