Method Details

derive

protected Matrix34dPair derive(Object object,
 boolean asNode,
 Matrix34dPair parentValue,
 Matrix34dPair placeIn,
 GraphState gs)

Specified by:

derive in class ObjectTreeAttribute<Matrix34dPair>

dependsOn

public boolean dependsOn(Attribute[] a)

Specified by:

dependsOn in class ObjectTreeAttribute<Matrix34dPair>

getInitialValue

protected Matrix34dPair getInitialValue(GraphState gs)

Specified by:

getInitialValue in class ObjectTreeAttribute<Matrix34dPair>

get

public static Matrix34d get(Object object,
 boolean asNode,
 GraphState gs,
 boolean post)

Returns the global coordinate system of object. If post is true, the coordinate system behind the object is returned, which is the basis for the coordinate system of children, otherwise the method returns the coordinate system in which the shape of the object is defined.

The returned matrix must not be modified.

Parameters:

object - an object in the scene graph

asNode - is object a node or an edge?

gs - the current graph state

post - include the post-transformation (behind the object)?

Returns:

global coordinate system, matrix must not be modified

getParentValue

public static Matrix34d getParentValue(Object object,
 boolean asNode,
 GraphState gs,
 boolean post)

Returns the global coordinate system of the parent of object. If post is true, the coordinate system behind the parent is returned, which is the basis for the coordinate system of object, otherwise the method returns the coordinate system in which the shape of the parent is defined.

The returned matrix must not be modified.

Parameters:

object - an object in the scene graph

asNode - is object a node or an edge?

gs - the current graph state

post - include the post-transformation (behind the parent)?

Returns:

global coordinate system of parent, matrix must not be modified
