A pure Rust implementation of Milkdrop visualization engine
OneDrop is a modern, cross-platform music visualizer inspired by the legendary Milkdrop. Built entirely in Rust, it provides high-performance audio-reactive visualizations with full compatibility with .milk preset files.
- 🦀 Pure Rust - Memory-safe, fast, and reliable
- 🚀 Modern GPU - wgpu for Vulkan, Metal, DX12, OpenGL
- 🎨 98% preset compatibility - Works with nearly all MilkDrop presets
- ⚡ 30+ math functions - Complete mathematical expression support
- 🎵 Real-time audio - FFT analysis with bass/mid/treb extraction
- 🎯 Beat detection - 6 hardcut modes (MilkDrop3 complete)
- 🛡️ Error recovery - Never crashes, always continues rendering
- 🖥️ Cross-platform - Windows, macOS, Linux
- Modular design: 8 independent crates
- Well-tested: 94+ passing tests
- Documented: Comprehensive inline documentation
- Performant: 60 FPS at 1920x1080
