A simple Javascript experiment with casting 2D shadows from cyclic polygon shapes (polygons with vertices which can be inscribed in a circle).

A cyclic polygon is a polygon with vertices upon which a circle can be circumscribed -- MathWorld

Why?

This is personal project of mine, extended from the curiosity of creating lighting effects in Flash and the soft-shadows I've been built in GameMaker.

Current State

• Hard-edged shadows are implemented for n-sided polygons and circles
• Soft-edged shadows are only an extended goal (the current attempt was premature)
• Multiple lights look horrible, but they all cast shadows
