Surfaces of Revolution

A module of Egg Math for Chickscope.

Rotating a curve around an axis produces a surface of revolution, which has rotational symmetry around that axis. Here are some example surfaces of revolution; the white plane curves at left, when rotated about the green axes, generate the surfaces at right.

This Cartesian oval (with p~1.61)		yields this ovoid egg shape
This squiggle		yields this cup
These circles		yield this doughnut (torus)
