Code WGSL shaders & export HQ frames: powered by wgpu and has hot reload for shaders

A tool for experimenting with WGSL shaders, it uses wgpu for rendering, egui for the UI and winit for windowing :-)

Current Features

• Hot shader reloading
• Compute & Fragment shader support
• Multi-pass, atomics etc
• Interactive parameter adjustment, ez media imports through egui
• Easily use HDR textures via UI
• Easily use your own videos as textures (thanks to the gstreamer)
• Audio/Visual synchronization: Spectrum and BPM detection via gstreamer
• Export HQ frames via egui

Current look

Keys

• F full screen/minimal screen, H hide egui

Usage

• If you want to try your own shaders, check out the usage.md.
• Optional Media Support: GStreamer dependencies are optional - use --no-default-features for lightweight builds with pure GPU compute shaders.
• When using cuneus as a dependency (via cargo add):
  • Add bytemuck = { version = "1", features = ["derive"] } to dependencies (derive macros can't be re-exported)
  • Copy build.rs to your project root to configure GStreamer paths (only needed for media features)
  • then simply use use cuneus::prelude::*;

Run examples

• cargo run --release --bin *file*

• Or download on the releases

• Or, as the best method, use tui browser via ratatui (thanks to davehorner):

  cargo run --example tui_browser
