Camera Animations on Circles, Spirals, Helices, and Conical Spirals
This Demonstration shows animations described by parametric equations. The camera moves on a circle, an Archimedes's spiral, a helix, and a conical spiral. The camera (shown as a little sphere moving on the curves) and its view of a simple 3D scene (which consists of a table and some things on it) are shown simultaneously.
