Constructor Details

GeometryGroupNode

public GeometryGroupNode()

Construct a GeometryGroupNode

GeometryGroupNode

public GeometryGroupNode(String name)

Construct a GeometryGroupNode

Parameters:

name - The name of the GeometryGroupNode.

Method Details

getGeometryStartIndex

public static int getGeometryStartIndex(Geometry geom)

setGeometryStartIndex

protected static void setGeometryStartIndex(Geometry geom,
 int startIndex)

onTransformChange

public abstract void onTransformChange(Geometry geom)

Called by geom to specify that its world transform has been changed.

Parameters:

geom - The Geometry whose transform changed.

onMaterialChange

public abstract void onMaterialChange(Geometry geom)

Called by geom to specify that its material has been changed.

Parameters:

geom - The Geometry whose material changed.

Throws:

UnsupportedOperationException - If this implementation does not support dynamic material changes.

onMeshChange

public abstract void onMeshChange(Geometry geom)

Called by geom to specify that its mesh has been changed. This is also called when the geometry's lod level changes.

Parameters:

geom - The Geometry whose mesh changed.

Throws:

UnsupportedOperationException - If this implementation does not support dynamic mesh changes.

onGeometryUnassociated

public abstract void onGeometryUnassociated(Geometry geom)

Called by geom to specify that it has been unassociated from its GeometryGroupNode. Unassociation occurs when the Geometry is detached from its parent Node.

Parameters:

geom - The Geometry which is being unassociated.
