The Engineering Challenge
Rendering dense computational graphs with hundreds of interconnected nodes in traditional SVG/DOM frameworks causes severe frame drops and jank due to DOM tree thrashing.
The Architectural Solution
Designed a hybrid WebGL 2.0 instanced rendering pipeline with OffscreenCanvas running in a dedicated Web Worker, leaving the main UI thread 100% free for user input and gesture springs.
Implementation Details
Wrote custom GLSL vertex shaders for instanced bezier curve connection rendering.
Implemented spring physics for drag-and-drop node snapping.
Integrated real-time collaborative state synchronization via WebSocket workers.
Enforced accessibility keyboard navigation across the spatial coordinate grid.
