// Class : PhysxPlaneShape
|
|
// Description : 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.
