Class Matrix4fStack

java.lang.Object

org.joml.Matrix4f

org.joml.Matrix4fStack

All Implemented Interfaces:

Externalizable, Serializable, Matrix4fc

public class Matrix4fStack
extends Matrix4f

A stack of many Matrix4f instances. This resembles the matrix stack known from legacy OpenGL.

This Matrix4fStack class inherits from Matrix4f, so the current/top matrix is always the Matrix4fStack/Matrix4f itself. This affects all operations in Matrix4f that take another Matrix4f as parameter. If a Matrix4fStack is used as argument to those methods, the effective argument will always be the current matrix of the matrix stack.

Constructor Detail

Matrix4fStack

public Matrix4fStack(int stackSize)

Create a new Matrix4fStack 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 Matrix4fStack simply only consists of this Matrix4f

Matrix4fStack

public Matrix4fStack()

Do not invoke manually! Only meant for serialization.

Invoking this constructor from client code will result in an inconsistent state of the created Matrix4fStack instance.

Method Detail

clear

public Matrix4fStack clear()

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

Returns:

this

pushMatrix

public Matrix4fStack 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 Matrix4fStack popMatrix()

Decrement the stack pointer by one.

This will effectively dispose of the current matrix.

Returns:

this

hashCode

public int hashCode()
