Triceratops is a Grasshopper plugin that exports geometry from Grasshopper to a JSON file in the Three.js object scene format.

Triceratops exports Three.js scenes from Grasshopper for using in web based 3D visualizions. The plugin makes it easy to leverage Three.js to make web based 3d scenes. Triceratop's objects mirror objects and terminology used by Three.js, so those with Three.js experience will find them familiar.

The plugin allows the user to input geometry (meshes, lines, and points), assign materials (like meshStandardMaterial), and then export a Three.js scene that is ready to load using THREE.ObjectLoader().
