Method Detail

newInstance

public Element newInstance()

Description copied from class: Element

Creates a new instance initialized to the default values for the state element. All concrete Element subclasses must implement this operation.

Overrides:

newInstance in class ModelMatrixElement

getInstance

public static GLModelMatrixElement getInstance(State state)

enable

public static void enable(State defaultState)

push

public void push(State state)

Description copied from class: Element

Pushes the element, allowing for side effects to occur. Default method does nothing.

Overrides:

push in class ModelMatrixElement

pop

public void pop(State state,
                Element previousTopElement)

Description copied from class: Element

Pops the element, allowing for side effects to occur. Default method does nothing. NOTE that it is not legal to call State.getElement() in the implementation of this method, which is why the previous top element is provided as an argument.

Overrides:

pop in class Element

makeEltIdent

public void makeEltIdent()

Description copied from class: ModelMatrixElement

Sets this element to the identity matrix.

Overrides:

makeEltIdent in class ModelMatrixElement

multElt

public void multElt(Mat4f matrix)

Description copied from class: ModelMatrixElement

Multiplies this element by the given matrix.

Overrides:

multElt in class ModelMatrixElement
