A desktop client for Shadertoy written in Rust

Desktop Shadertoy client, written in Rust.

While it's still a work in progress, you can run some example shaders to see that it's working:

cargo run --release -- --example seascape
cargo run --release -- --example elemental-ring

Make sure you build/run in release mode; textures take several seconds to load in debug mode. You can also download from crates.io.

So long as you restrict yourself to the supported uniforms, shaders copy-pasted directly from Shadertoy should run with no modifications (if they don't, feel free to file an issue or open a pull request). The following uniforms are currently supported, with more coming soon:

• iGlobalTime
• iTime (same as iGlobalTime; iGlobalTime will eventually be deprecated by Shadertoy)
• iResolution
• iMouse
• iFrame
• iChannel0, iChannel1, iChannel2, iChannel3
  • These are 2D RGBA textures

You can press F5 to reload the shader if you've edited it since launching the app.

You can also download (and optionally run) shaders directly from Shadertoy if you have the URL or shader ID. For example, to download the classic Seascape shader, you can run

shadertoy get https://www.shadertoy.com/view/Ms2SD1

or just

shadertoy get Ms2SD1

Add the -r/--run flag to automatically run the downloaded shader

For now, the CLI looks like this:
