The c3DEffectCoilPattern Folder

This folder contains SVG documents that are based on polar equations combined with a a set of ellipses that appear to coil around each of the rendered curves. The example from this folder is the SVG document , which contains an Archimedean spiral with a coil-like pattern of ellipses that appear to wrap around the Archimedean curve. The ellipses in the coil are rendered with a multi-stop radial gradient that is defined in an SVG defs element (at the bottom of each document) that creates a three-dimensional effect.
