Enables streaming and rendering of massive 3D datasets with adaptive level-of-detail for architecture and geospatial applications worldwide.

Utilities for parsing and rendering GeoJSON data as three.js geometry. Simplifies the visualization of geographic vector data including polygons, lines, and points with support for ellipsoidal projections.

A long-standing & still growing spatial query system for three.js trusted for fast and accurate spatial queries. Used for accelerating raycasting, collision detection, and spatial queries with BVH-based acceleration structures.

GPU-accelerated path tracing renderer for physically based rendering on the web. Supports PBR materials, area lights, depth of field, and volumetric fog for high-quality rendering visuals.

Package for extracting and projecting visible edges and silhouettes from 3D geometry. Useful for generating technical drawings, floor plans, and architectural visualizations with line-based rendering.

Loads and displays URDF robot description files in three.js, enabling robot visualization and simulation in web-based interfaces. Used at NASA JPL for rover state visualization in Mars operations tools.

Javascript-based parser for Xacro robot description files, the macro language used to build modular URDF robot definitions enabling integration with commonly used ROS formats.

Inverse kinematics solver for closed-chain and parallel mechanisms commonly found in robotics. Enables solving complex linkage systems like hexapod platforms, delta robots, and other parallel manipulators.
