Constructor Detail

EyeTarget

public EyeTarget()

Creates a new instance of EyeTarget

Method Detail

getTargetX

public float getTargetX()

getTargetY

public float getTargetY()

setTargetSpeed

public void setTargetSpeed(float speed)

getTargetSpeed

public float getTargetSpeed()

repaint

public void repaint()

Specified by:

repaint in interface javax.media.opengl.GLAutoDrawable

Overrides:

repaint in class java.awt.Component

init

public void init(javax.media.opengl.GLAutoDrawable drawable)

Called by the drawable immediately after the OpenGL context is initialized. Can be used to perform one-time OpenGL initialization such as setup of lights and display lists. Note that this method may be called more than once if the underlying OpenGL context for the GLAutoDrawable is destroyed and recreated, for example if a GLCanvas is removed from the widget hierarchy and later added again.

Specified by:

init in interface javax.media.opengl.GLEventListener

display

public void display(javax.media.opengl.GLAutoDrawable drawable)

Called by the drawable to initiate OpenGL rendering by the client. After all GLEventListeners have been notified of a display event, the drawable will swap its buffers if setAutoSwapBufferMode is enabled.

Specified by:

display in interface javax.media.opengl.GLEventListener

reshape

public void reshape(javax.media.opengl.GLAutoDrawable drawable,
                    int x,
                    int y,
                    int width,
                    int height)

called on reshape of canvas. Sets the scaling for drawing pixels to the screen.

Specified by:

reshape in interface javax.media.opengl.GLEventListener

displayChanged

public void displayChanged(javax.media.opengl.GLAutoDrawable drawable,
                           boolean modeChanged,
                           boolean deviceChanged)

Called by the drawable when the display mode or the display device associated with the GLAutoDrawable has changed. The two boolean parameters indicate the types of change(s) that have occurred. ( !!! CURRENTLY UNIMPLEMENTED !!! )

An example of a display mode change is when the bit depth changes (e.g., from 32-bit to 16-bit color) on monitor upon which the GLAutoDrawable is currently being displayed.

An example of a display device change is when the user drags the window containing the GLAutoDrawable from one monitor to another in a multiple-monitor setup.

The reason that this function handles both types of changes (instead of handling mode and device changes in separate methods) is so that applications have the opportunity to respond to display changes the most efficient manner. For example, the application may need make fewer adjustments to compensate for a device change if it knows that the mode on the new device is identical the previous mode.
