CS155 Computer Graphics
Snowman Lab - Part 3
In the third part of the snowman lab, you'll build a scene graph for your snowman. You should work in pairs.
The scene graph for the basic snowman is shown below. (There are some other forms that would work but please use
the one below.)
For each node, determine the transform needed to move from the node's coordinate system to its parents. (As before, your
basic primitive will be a sphere with radius 1 centered at the origin.)
Now modify your ray file from last time to represent the scene graph, where each node is a separate group. (Note:
groups can be embedded in other groups.) Test your ray file with the ray tracer.
