Yuanzhen Pan and Eliza McNair
The scene below contains a Chirstmas tree with trunk, foliage, and star, as well as a point system of small sparkles. The room itself, the tree, and the points are all created with texture mapping and either MeshLambertMaterial or MeshPhongMaterial. The foliage is a bump map, as well. To create a tree scene, invoke the ypanemcnairXmasTree() method defined in the accompanying JS file. The dat.GUI can be used to turn the ambient lights on and off - but only when it's "bedtime". The scene also contains a spotlight.
