Constructor Detail

HingeJoint

public HingeJoint(org.openmali.vecmath2.Vector3f rotationAxis,
                  org.openmali.vecmath2.Vector3f translationAxis,
                  float length)

Creates a new HingeJoint

Parameters:

rotationAxis - Axis about which the attached object will rotate

translationAxis - Axis about which the object is tied to the joint

length - Length of the joint (where/how far should the next joint begin?)

HingeJoint

public HingeJoint(org.openmali.vecmath2.Vector3f rotationAxis,
                  org.openmali.vecmath2.Vector3f translationAxis,
                  float length,
                  float angle)

Creates a new HingeJoint

Parameters:

rotationAxis - Axis about which the attached object will rotate

translationAxis - Axis about which the object is tied to the joint

length - Length of the joint (where/how far should the next joint begin?)

angle - Initial angle of the HingeJoint

Method Detail

getStartGroup

public Group getStartGroup()

Returns:

the display group, to which you can add some Shapes for your joint to be visible.

getEndGroup

public Group getEndGroup()

Returns:

the display group, to which you can add some Shapes for your joint to be visible.

addChild

public void addChild(Joint j)

Add a child joint to this one

Specified by:

addChild in class Joint

Parameters:

j - The new joint to be added

removeChild

public void removeChild(Joint j)

Remove a child joint from this one

Specified by:

removeChild in class Joint

Parameters:

j - The joint to be removed from

traverse

public boolean traverse(DetailedTraversalCallback callback)

Description copied from class: Group

Traverses the scenegraph from this node on. If this Node is a Group it will recusively run through each child.

Overrides:

traverse in class Group

Parameters:

callback - the listener is notified of any traversed Node on the way

Returns:

if false, the whole traversal will stop
