A rendering of a COLLADA file in three.js (release 69 - r71 produces jagged edges in our attempts).
WebGL is used to actually render the scene. Attempting to use Canvas or SVG renderers results in an issue with Hidden Surface Detrermination, causing artifacts to be displayed above the elongated thin face of the colored object.
