Exedra
A shared 3D whiteboard in the browser for explaining how something works, blocking out a level, or planning a set. Open a link and place, light, and annotate objects together.
Every change goes through an authoritative C++ server and streams to everyone in the room. I built the engine’s undo and redo, the interpolation that keeps other people’s edits and cameras smooth, the server-authoritative material library, the annotation, viewpoint, and measurement tools, custom model uploads, and named room saves.
