, developed by Ambiera. The aim of the library is to provide an API for making it easier developing 3D content for the web. It is supposed to be used together with its commercial 3D world editor CopperCube, but it can also be used without.

History

In February 2010, Ambiera introduced CopperLicht and showcased it by providing a demo website, showing a Quake III Arena level rendered in real time in the browser window. The library was originally intended to be used as a

backend for the CopperCube editor, but then the developers decided to make the library free to be used by the public. In November 2014, CopperLicht was made free and open source, based on a zlib style license.

Features

CopperLicht includes the following features: * 3D rendering based on a hierarchical scene graph * Pre-created materials and shaders, including pre-calculated

lightmap A lightmap is a data structure used in lightmapping, a form of surface caching in which the brightness of surfaces in a virtual scene is pre-calculated and stored in texture maps for later use. Lightmaps are most commonly applied to static o ...
