Class Matrix3dStack

java.lang.Object

org.joml.Matrix3d

org.joml.Matrix3dStack

All Implemented Interfaces:

Externalizable, Serializable, Matrix3dc

public class Matrix3dStack
extends Matrix3d

A stack of many Matrix3d instances. This resembles the matrix stack known from legacy OpenGL.

This Matrix3dStack class inherits from Matrix3d, so the current/top matrix is always the Matrix3dStack/Matrix3d itself. This affects all operations in Matrix3d that take another Matrix3d as parameter. If a Matrix3dStack is used as argument to those methods, the effective argument will always be the current matrix of the matrix stack.

Constructor Detail

Matrix3dStack

public Matrix3dStack(int stackSize)

Create a new Matrix3dStack 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 Matrix3dStack simply only consists of this Matrix3d

Matrix3dStack

public Matrix3dStack()

Do not invoke manually! Only meant for serialization.

Invoking this constructor from client code will result in an inconsistent state of the created Matrix3dStack instance.

Method Detail

clear

public Matrix3dStack clear()

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

Returns:

this

pushMatrix

public Matrix3dStack 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 Matrix3dStack 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 Matrix3d

equals

public boolean equals(Object obj)

Overrides:

equals in class Matrix3d

Throws:

IOException

readExternal

public void readExternal(ObjectInput in)
                  throws IOException

Specified by:
