Class Matrix4dStack

org.joml.Matrix4d

org.joml.Matrix4dStack

All Implemented Interfaces:

Externalizable, Serializable, Matrix4dc

public class Matrix4dStack
extends Matrix4d

A stack of many Matrix4d instances. This resembles the matrix stack known from legacy OpenGL.

This Matrix4dStack class inherits from Matrix4d, so the current/top matrix is always the Matrix4dStack/Matrix4d itself. This affects all operations in Matrix4d that take another Matrix4d as parameter. If a Matrix4dStack is used as argument to those methods, the effective argument will always be the current matrix of the matrix stack.

Constructor Detail

Matrix4dStack

public Matrix4dStack(int stackSize)

Create a new Matrix4dStack 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 Matrix4dStack simply only consists of this Matrix4d

Matrix4dStack

public Matrix4dStack()

Do not invoke manually! Only meant for serialization.

Invoking this constructor from client code will result in an inconsistent state of the created Matrix4dStack instance.

Method Detail

clear

public Matrix4dStack clear()

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

Returns:

this

pushMatrix

public Matrix4dStack 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 Matrix4dStack popMatrix()

Decrement the stack pointer by one.

This will effectively dispose of the current matrix.

Returns:

this
