Method Details

getPolygonizableSource

public ContextDependent getPolygonizableSource(GraphState gs)

Description copied from interface: Polygonizable

Defines the data source on which the polygonization depends.

Specified by:

getPolygonizableSource in interface Polygonizable

Parameters:

gs - the current graph state

Returns:

the data source

pick

 Vector3d direction,
 Matrix4d transformation,
 PickList list)

Description copied from interface: Pickable

Computes intersections of a given ray with this shape.

Specified by:

pick in interface Pickable

Parameters:

node - the object of which this shape is an attribute

asNode - true iff object is a node

origin - the origin of the ray, in local coordinates

direction - the direction of the ray, in local coordinates

transformation - the transformation from local coordinates to world coordinates

list - the list to which intersections have to be added

getPolygonization
