GLDF-RS-WASM

A WebAssembly-based GLDF (General Lighting Data Format) viewer and editor.

Overview

GLDF-RS-WASM provides an interactive web application for viewing and editing GLDF files directly in the browser. It leverages WebAssembly for high-performance parsing and rendering of lighting product data.

Features

• Modern UI: Clean, responsive interface built with Tailwind CSS
• GLDF Parsing: Load and parse GLDF container files client-side
• L3D 3D Viewer: WebGL-based 3D rendering of L3D luminaire models with orbit/zoom controls
• LDT/IES Diagrams: Interactive photometry polar diagrams with C-plane visualization
• Tabbed Editor: Edit header, variants, light sources, and files in organized tabs
• File Browser: View and download embedded assets (images, photometry, 3D models)
• Drag & Drop: Easy file upload via drag and drop
• Multi-L3D Support: Render GLDF files containing multiple L3D geometries

Dependencies

This crate relies on excellent Rust libraries for the heavy lifting:

Live Demo

Try it at: https://gldf.icu

Embedded Eulumdat files can be opened directly in https://eulumdat.icu - a WASM-based Eulumdat editor and viewer that can also export to IESNA format.
