A face is a single Non-uniform Rational B-Spline (NURBS) and is the smallest area entity. It has a separate underlying mathematical definition, specified when it was created.
All faces are represented mathematically with the following formulations:
• | plane |
• | cylinder/cone |
• | sphere |
• | torus |
• | NURBS |
A surface can be made up of a single face type or of multiple face types. Multiple types are used for more complex surfaces that contain sharp corners or highly complex shapes.
