Rusty Shadertoy Browser

Crate Build Status Build Status MIT/Apache FOSSA Status

Small Shadertoy browser & viewer for Mac built in Rust.

This application uses the Shadertoy REST API to search for Shadertoys and then downloads them locally and converts them using shaderc-rs and spirv-cross to be natively rendered on Mac using metal-rs.

Warning: Some of the Shadertoy shaders are extremely demanding of your GPU and cause system to be unresponsive.

The API queries are done through the shadertoy crate, which is also part of this repository in src/shadertoy

Render Output

Building

First make sure you have Rust installed installed. Then building & running is easy:

$ git clone https://github.com/repi/shadertoy-browser
$ cd shadertoy-browser
$ cargo build --release

# this will download and view all shadertoys with "car" in the name
$ cargo run --release -- -s car

Usage

Keys:

  • LEFT and RIGHT - switch between shadertoys.
  • SPACE - toggle grid view mode
  • ENTER - open shadertoy.com for current shader

If the screen is red that indicates the shader wasn't able to be built.

Optional command-line settings:

USAGE:
    shadertoy-browser [FLAGS] [OPTIONS]

FLAGS:
        --help        Prints help information
    -h, --headless    Don't render, only download shadertoys
    -V, --version     Prints version information
    -v, --verbose     More verbose log output, including list of all shadertoys found

OPTIONS:
    -k, --apikey <key>                Set shadertoy API key to use. Create your key on https://www.shadertoy.com/myapps
                                      [default: BtHtWD]
    -f, --filter <filter>...          Inclusion filters [values: VR, SoundOutput, SoundInput, Webcam, MultiPass,
                                      MusicStream]
    -y, --gridheight <grid_height>    Grid height [default: 4]
    -x, --gridwidth <grid_width>      Grid width [default: 4]
    -l, --limit <limit>               The maximum number of shaders to download. -1 = no limit [default: -1]
    -o, --order <order>               Sort order [default: Popular]  [values: Name, Love, Popular, Newest, Hot]
    -h, --resheight <res_height>      Window resolution height [default: 768]
    -w, --reswidth <res_width>        Window resolution width [default: 1024]
    -s, --search <string>             Search string to filter which shadertoys to get
    -t, --threads <threads>           How many threads to use for downloading & processing shaders. 0 = disables
                                      threading, -1 = use all logical processors [default: -1]

To use the Rust shadertoy API directly in another app or library, check out the shadertoy crate, docs and README.

Todo

This repo and app is a bit of an experimental Rust test range, and it is not intended to support everything or all shadertoys. But here are a couple of things I would like to implement going forward:

  • Rendering on Windows using DX12 and DXC
  • Rendering backend using SPIRV
  • Be able to click to select a shadertoy in grid view
  • Basic IMGUI for interactive searching & filtering
  • Async future based version of the Shadertoy client REST API
  • Async background download and building of shadertoys
  • Proper key-value cache store instead of files
  • Support shadertoys that use textures & buffers
  • Support shadertoys that use multiple passes
  • Support shadertoys that use keyboard input
