Class Transform

java.lang.Object
  wt.epm.structure.Transform

All Implemented Interfaces:

Externalizable, Serializable, NetFactor, ObjectMappable

public class Transform
extends Object
implements ObjectMappable, Externalizable

Transform does not support any mathematical operations. Instead, it provides methods to convert back and forth to Matrix4d. Matrix4d is class is in the Java3D vecmath package that supports all kinds of mathematical operations. Interfacing is done through the standard Matrix4d methods such as getRotationScale and get ( forTranslation vector). This implies that any Matrix4d sent or gotten must be constructed in the proper format. The format is row-major, thus the translation vector is stored in the third column of the matrix. The units of the translation vector must be meters.

Use the newTransform static factory method(s), not the Transform constructor, to construct instances of this class. Instances must be constructed using the static factory(s), in order to ensure proper initialization of the instance.
