Graphite is a free, open-source vector and raster graphics editor with a fully nondestructive editing workflow. It combines layer-based compositing with node-based generative design, enabling procedural content creation. The system is architected as a multi-crate Rust workspace with a desktop application (using Chromium Embedded Framework for UI and wgpu for GPU rendering) and a web frontend (Svelte + Vite compiled to WebAssembly). The core document model is a node graph executed by an interpreted runtime with GPU shader support via rust-gpu. Storage uses a CRDT-based format (`.gdd`) with content-addressed deltas, history, and session state, supporting collaborative editing and undo/redo. The editor features a comprehensive tool system (select, pen, brush, shape, text, etc.), a node graph editor, color management, raw image decoding, and vector path operations. The frontend communicates with the Rust backend through a message-passing architecture with hierarchical message types and a dispatcher pattern. The project also includes a CLI tool for export, a build system (cargo-run), and extensive developer tooling (bisect tool, crate hierarchy visualizer, node documentation generator).
The Universal Transition Shader is a Godot shader that provides a wide variety of transition effects (wipes, fades, masks, shapes, and clock wipes) with extensive customization options. It uses a grid system to allow for complex patterns like staggering, mirroring, and cell-based animations. The shader is self-contained and can be applied to any CanvasItem in Godot, making it a reusable tool for game developers and creators.
