Lily Pad Models

All the lily pads and stems were modelled in Mathematica; the screen shot below shows the basic form of the equations used to model both the pads and the stems. The intuition used to create the lily pad models is as follows:

The model of the lily pad stems can be thought of as sweeping a circle along a curve defined by sines and cosines.

After creating all of the models in Mathematica, the geometry was outputted to PBRT scene files and referenced in the main scene file. We used the Mathematica to PBRT converter available at Rotations and translations were applied to the models to place them so they closely matched up with the scene.
