Class IndexedLineSet

java.lang.Object

de.jreality.scene.SceneGraphNode

de.jreality.scene.Geometry

de.jreality.scene.PointSet

de.jreality.scene.IndexedLineSet

Direct Known Subclasses:

IndexedFaceSet

public class IndexedLineSet
extends PointSet

A geometric object consisting of a set of edges: lists of vertices joined by line segments.

Accessing instances of this class directly requires use of the class DataList. Users who prefer to avoid this are recommended to use IndexedLineSetFactory to construct instances of this class.

Method Detail

getNumEdges

public int getNumEdges()

The number of edges defines the length of all data lists associated with edge attributes.

setNumEdges

public void setNumEdges(int numEdges)

Sets the number of edges, implies removal of all previously defined edge attributes.

Parameters:

numEdges - the number of edges to set >=0

getEdgeAttributes

public DataListSet getEdgeAttributes()

Returns a read-only view to all currently defined edge attributes. You can copy all currently defined edge attributes to another IndexedLineSet using target.setEdgeAttributes(source.getEdgeAttributes()) These attributes are copied then, not shared. Thus modifying either source or target afterwards will not affect the other.
