Pumpkin Tea
This project was created using Pixar’s RenderMan and customized .rib files.
REFERENCE/INSPIRATION
Inspiration for teapot appearance.

FINAL THOUGHTS
The external .rib files (listed below) are normally generated automatically by applications such as Houdini and Maya. However, writing .rib files with a text editor focuses attention on the way that elements such as geometry, shading, lighting and, coordinate systems are presented to Pixar's RIB rendering system, and provides the user with more control.
