Class Transformation

java.lang.Object

de.jreality.scene.SceneGraphNode

de.jreality.scene.Transformation

public class Transformation
extends SceneGraphNode

A simple transformation class which wraps a 4x4 real matrix. Access is read-only. When contained as a field in an instance of SceneGraphComponent, this transformation is applied to any geometry contained in the component as well as to all children.

For generating and manipulating matrices meeting specific constraints (isometries, etc.) see P3, MatrixBuilder and FactoredMatrix.

For other support, see DefaultMatrixSupport.
