Constructor Detail

TextureMatrix

public TextureMatrix()

Initializes a TextureMatrix to the identity matrix.

TextureMatrix

public TextureMatrix(float m11,
                     float m12,
                     float m13,
                     float m14,
                     float m21,
                     float m22,
                     float m23,
                     float m24,
                     float m31,
                     float m32,
                     float m33,
                     float m34,
                     float m41,
                     float m42,
                     float m43,
                     float m44)

Initializes a TextureMatrix. The subscripts define [row][column].

Parameters:

m11 - 1,1

m12 - 1,2

m13 - 1,3

m14 - 1,4

m21 - 2,1

m22 - 2,2

m23 - 2,3

m24 - 2,4

m31 - 3,1

m32 - 3,2

m33 - 3,3

m34 - 3,4

m41 - 4,1

m42 - 4,2

m43 - 4,3

m44 - 4,4

TextureMatrix

public TextureMatrix(AffineTransform matrix)

Initializes a TextureMatrix from a AffineTransform. The upper left 2x2 matrix defines rotation and scaling. The top two elements of the last column define translation.

Parameters:

matrix - matrix

TextureMatrix

public TextureMatrix(Rectangular corner0,
                     Rectangular corner1,
                     Rectangular corner2,
                     Rectangular corner3)

Initializes a TextureMatrix from texture corner points. Normally, a texture is mapped such that the lower left corner is texture coordinate (0, 0), the lower right is (1, 0), the upper right is (1, 1), and the upper left is (0, 1). This code remaps those corners to new corners. For example, remapping the lower left corner to (0.5, 0), the lower right to (1, 0.5), the upper right to (0.5, 1), and the upper left to (0, 0.5) would rotate the texture 45 degress.

Parameters:

corner0 - The new location of the texture's lower left corner.

corner1 - The new location of the texture's lower right corner.

corner2 - The new location of the texture's upper right corner.

corner3 - The new location of the texture's upper left corner.

Method Detail

finalize

protected void finalize()
                 throws Throwable

Description copied from class: java.lang.Object

Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. A subclass overrides the finalize method to dispose of system resources or to perform other cleanup.

The general contract of finalize is that it is invoked if and when the Java™ virtual machine has determined that there is no longer any means by which this object can be accessed by any thread that has not yet died, except as a result of an action taken by the finalization of some other object or class which is ready to be finalized. The finalize method may take any action, including making this object available again to other threads; the usual purpose of finalize, however, is to perform cleanup actions before the object is irrevocably discarded. For example, the finalize method for an object that represents an input/output connection might perform explicit I/O transactions to break the connection before the object is permanently discarded.

The finalize method of class Object performs no special action; it simply returns normally. Subclasses of Object may override this definition.

The Java programming language does not guarantee which thread will invoke the finalize method for any given object. It is guaranteed, however, that the thread that invokes finalize will not be holding any user-visible synchronization locks when finalize is invoked. If an uncaught exception is thrown by the finalize method, the exception is ignored and finalization of that object terminates.

After the finalize method has been invoked for an object, no further action is taken until the Java virtual machine has again determined that there is no longer any means by which this object can be accessed by any thread that has not yet died, including possible actions by other objects or classes which are ready to be finalized, at which point the object may be discarded.

The finalize method is never invoked more than once by a Java virtual machine for any given object.

Any exception thrown by the finalize method causes the finalization of this object to be halted, but is otherwise ignored.

Overrides:

finalize in class Object

Throws:

Throwable - the Exception raised by this method
