Method Detail

processEvent

public void processEvent(AWTEvent e)

This override let GLUT.processEvent(AWTEvent) be informed of AWTEvent traversing this canvas (mouse, keyboard, resize). One should register GLUT.glutDisplayFunc(String) to register a display callback, GLUT.glutMotionFunc(String) to register a mouse motion callback, etc. NB : This relies on the fact the GLUT already invoked {@link this#glut_enable_events}.

Overrides:

processEvent in class Component

glut_enable_events

public void glut_enable_events(long cap,
                               boolean state)

update

public void update(Graphics g)

Overrides:

update in class Canvas

paint

public void paint(Graphics g)

Overrides:

paint in class Canvas

getPixelScaleFromG2D

protected void getPixelScaleFromG2D(Graphics2D g2d)

Pixel scale is used to model the pixel ratio introduced by HiDPI

getGL

public GL getGL()

getGLU

public GLU getGLU()

getGLUT

public GLUT getGLUT()

forceRepaint

public void forceRepaint()

Can be used to update image if camera has changed position. FIXME : Warning if this is invoked by a thread external to AWT, maybe this will require to redraw GL while GL is already used by AWT.
