/**
|
|
* A plane collision detection primitive. By default it is configured to be
|
|
* the y == 0 plane. You can then set a normal and a d to specify an
|
|
* arbitrary plane. d is the distance of the plane from the origin along the
|
|
* normal, assuming the normal is normalized. Thus the plane equation is:
|
|
* normal.x * X + normal.y * Y + normal.z * Z = d
|
|
*
|
|
* Note: the plane does not represent an infinitely thin object, but rather a
|
|
* completely solid negative half space (all points p for which normal.dot(p)
|
|
* - d < 0 are inside the solid region.)
|
|
*
|
|
* Each shape is owned by an actor that it is attached to.
|
|
*
|
|
* An instance can be created by calling the createShape() method of the
|
|
* PhysxActor object that should own it, with a PhysxPlaneShapeDesc object as
|
|
* the parameter, or by adding the shape descriptor into the PhysxActorDesc
|
|
* class before creating the actor.
|
|
*
|
|
* The shape is deleted by calling release() on the shape itself.
