Class Transformation

java.lang.Object

org.andengine.util.adt.transformation.Transformation

public class Transformation
extends java.lang.Object

This class is basically a java-space replacement for the native Matrix class.

Math taken from senocular.com.

This class represents an affine transformation with the following matrix:

 [ a , b , 0 ]
 [ c , d , 0 ]
 [ tx, ty, 1 ]

where:

• a is the x scale
• b is the y skew
• c is the x skew
• d is the y scale
• tx is the x translation
• ty is the y translation
