Public Methods

Method	Description
CalculateMassInertia ( ) : void
CompoundShape ( List shapes ) : System	Created a new instance of the CompountShape class.
CompoundShape ( TransformedShape shapes ) : System
GetBoundingBox ( Jitter.LinearMath.JMatrix &orientation, Jitter.LinearMath.JBBox &box ) : void	Gets the axis aligned bounding box of the orientated shape. (Inlcuding all 'sub' shapes)
MakeHull ( List &triangleList, int generationThreshold ) : void
Prepare ( Jitter.LinearMath.JBBox &box ) : int	Passes a axis aligned bounding box to the shape where collision could occour.
Prepare ( Jitter.LinearMath.JVector &rayOrigin, Jitter.LinearMath.JVector &rayEnd ) : int
SetCurrentShape ( int index ) : void	Sets the current shape. First CompoundShape.Prepare has to be called. After SetCurrentShape the shape immitates another shape.
SupportMapping ( Jitter.LinearMath.JVector &direction, Jitter.LinearMath.JVector &result ) : void	SupportMapping. Finds the point in the shape furthest away from the given direction. Imagine a plane with a normal in the search direction. Now move the plane along the normal until the plane does not intersect the shape. The last intersection point is the result.
UpdateShape ( ) : void
