 Three.js renderer implementation for the [3D Tiles format](https://github.com/AnalyticalGraphicsInc/3d-tiles/blob/master/specification/). The renderer supports most of the 3D Tiles spec features with a few exceptions. See [Issue #15](https://github.com/NASA-AMMOS/3DTilesRendererJS/issues/15) for information on which features are not yet implemented.
