ConicDisplay

class ConicDisplay extends PIXI.Container

Draws a segment of conic section represented by the equation k²- lm = 0, where k, l, m are lines.

This display-object shades the inside/outside of a conic section within a mesh.

A conic curve can be represented in the form: k² - lm = 0, where k, l, m are lines described in the form ax + by + c = 0. l and m are the tangents to the curve, and k is a chord connecting the points of tangency.
