Class Matrix3fStack

java.lang.Object

org.joml.Matrix3f

org.joml.Matrix3fStack

All Implemented Interfaces:

Externalizable, Serializable, Matrix3fc

public class Matrix3fStack
extends Matrix3f

A stack of many Matrix3f instances. This resembles the matrix stack known from legacy OpenGL.

This Matrix3fStack class inherits from Matrix3f, so the current/top matrix is always the Matrix3fStack/Matrix3f itself. This affects all operations in Matrix3f that take another Matrix3f as parameter. If a Matrix3fStack is used as argument to those methods, the effective argument will always be the current matrix of the matrix stack.

Constructor Detail

Matrix3fStack

public Matrix3fStack(int stackSize)

Create a new Matrix3fStack 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 Matrix3fStack simply only consists of this Matrix3f

Matrix3fStack

public Matrix3fStack()

Do not invoke manually! Only meant for serialization.

Invoking this constructor from client code will result in an inconsistent state of the created Matrix3fStack instance.

Method Detail

clear

public Matrix3fStack clear()

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

Returns:

this

pushMatrix

public Matrix3fStack 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 Matrix3fStack 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 Matrix3f

equals

public boolean equals(Object obj)

Overrides:

equals in class Matrix3f

writeExternal

public void writeExternal(ObjectOutput out)
                   throws IOException

Specified by:

writeExternal in interface Externalizable

Overrides:

writeExternal in class Matrix3f

Throws:

IOException

readExternal

public void readExternal(ObjectInput in)
                  throws IOException

Specified by:

readExternal in interface Externalizable

Overrides:

readExternal in class Matrix3f

Throws:

IOException
