Examples of Plane

com.ardor3d.math.Plane
A representation of a mathematical plane using a normal vector and a plane constant (d) whose absolute value represents the distance from the origin to the plane. It is generally calculated by taking a point (X) on the plane and finding its dot-product with the plane's normal vector. iow: d = N dot X
com.jme.math.Plane
com.jme3.math.Plane
Plane defines a plane where Normal dot (x,y,z) = Constant. This provides methods for calculating a "distance" of a point from this plane. The distance is pseudo due to the fact that it can be negative if the point is on the non-normal side of the plane. @author Mark Powell @author Joshua Slack

Plane class @author Emmanuel Bernard
org.mt4j.util.math.Plane
The Class Plane.
plane.Plane
toxi.geom.Plane
Class to describe and work with infinite generic 3D planes. Useful for intersection problems and classifying points.
vash.Plane
A 2D plane composed of floats. Contains extra information that we may need to iterate over elements in the plane, absent any external information.
