All Implemented Interfaces:

Externalizable, Serializable, Matrix3x2fc

public class Matrix3x2fStack
extends Matrix3x2f

A stack of many Matrix3x2f instances. This resembles the matrix stack known from legacy OpenGL.

This Matrix3x2fStack class inherits from Matrix3x2f, so the current/top matrix is always the Matrix3x2fStack/Matrix3x2f itself. This affects all operations in Matrix3x2f that take another Matrix3x2f as parameter. If a Matrix3x2fStack is used as argument to those methods, the effective argument will always be the current matrix of the matrix stack.

Constructor Detail

Matrix3x2fStack

public Matrix3x2fStack(int stackSize)

Create a new Matrix3x2fStack of the given size.

Initially the stack pointer is at zero and the current matrix is set to identity.

Parameters:

stackSize - the size of the stack. This must be at least 1, in which case the Matrix3x2fStack simply only consists of this Matrix3x2f

Matrix3x2fStack

public Matrix3x2fStack()

Do not invoke manually! Only meant for serialization.

Invoking this constructor from client code will result in an inconsistent state of the created Matrix3x2fStack instance.

Method Detail

clear

public Matrix3x2fStack clear()

Set the stack pointer to zero and set the current/bottom matrix to identity.

Returns:

this

pushMatrix

public Matrix3x2fStack pushMatrix()

Increment the stack pointer by one and set the values of the new current matrix to the one directly below it.

Returns:

this

popMatrix

public Matrix3x2fStack popMatrix()

Decrement the stack pointer by one.

This will effectively dispose of the current matrix.

Returns:

this

hashCode

public int hashCode()

Overrides:

hashCode in class Matrix3x2f

equals

public boolean equals(Object obj)

Overrides:

equals in class Matrix3x2f
