Default constructor

This event is fired when we increase the viewports paralax. We try to maintain the 3Dpointer at the same aparent distance to observer, so we try to maintain the same screen paralax.

MouseEvent mantains the coherence between pointer and windows mouse it receives the mouse events as a objet newMouse of MouseState

This field contains the maximum viewport size (OpenGl restriction)

Wheel event increments Cursor3D paralax if true Wheel event increments Viewport paralax if false

moveXYobs Pointer3D event

Right button

Pan event (Screen)

Increment of viewport paralax in a keyParalaxEvent (it is multiplied by the integer sended) Increment of pointer3D paralax in a mouse wheel event.

Depending on moveCursorNotViewport flag, paralax viewport event of moveZobs pointer3D event

Mouse state previous to the present event

Zoom event (Screen)

How much we increase the zoom with zoom event

If we use zoom/pan throught display displacements we must store the initial displayPosition

Wheel event increments Cursor3D paralax if true Wheel event increments Viewport paralax if false

Zoom and Pan are obtained throught Display displacements if true Zoom and Pan are obtained moving the Viewport if false It's better not to use both systems in the same program

Gets/Sets the paralax factor

Gets/Sets the zoom factor
