GraphiteEditor/Graphite
24,258View on GitHubGraphite is a node-based visual design environment that integrates vector illustration, raster image processing, and motion graphics generation into a single platform. It utilizes a functional reactive pipeline and a data-flow execution model to propagate state changes through a graph of interconnected nodes, allowing users to construct complex, automated design workflows. The platform distinguishes itself through a context-aware evaluation engine that injects runtime metadata—such as coordinate data and loop indices—directly into the node graph. This enables the creation of procedural geomet
Graphite is a node-based visual design environment with raster image processing capabilities, making it a genuine open-source photo editor, though its node-graph approach differs from traditional layer-based editors.
