Class Renderer3d

java.lang.Object
  org.jzy3d.plot3d.rendering.view.Renderer3d

All Implemented Interfaces:

java.util.EventListener, javax.media.opengl.GLEventListener

public class Renderer3d
extends java.lang.Object
implements javax.media.opengl.GLEventListener

The Renderer object is a GLEventListener, that makes openGL calls necessary to initialize and render a Scene for its parent ICanvas. A Renderer is directly embedded and controlled by a Canvas3d and should not be controlled by the user in normal uses. However, since the Renderer implements the GLEventListener interface, it may be incorporated into one of these GLAutoDrawable provided by JOGL:

• javax.media.opengl.GLCanvas for AWT or SWT display
• javax.media.opengl.GLJPanel for Swing display

Constructor Summary

Renderer3d(View view)
Initialize a Renderer attached to the given View.

Renderer3d(View view, boolean traceGL, boolean debugGL)
Initialize a Renderer attached to the given View, and activate GL trace and errors to console.

Method Summary

void	display(javax.media.opengl.GLAutoDrawable canvas) Called when the GLDrawable requires a rendering.
void	displayChanged(javax.media.opengl.GLAutoDrawable canvas, boolean modeChanged, boolean deviceChanged) Called when the device or display mode change.
void	dispose()
int	getHeight() Return the height that was given after the last resize event.
java.awt.image.BufferedImage	getLastScreenshot()
int	getWidth() Return the width that was given after the last resize event.
void	init(javax.media.opengl.GLAutoDrawable canvas) Called when the GLDrawable is rendered for the first time.
void	nextDisplayUpdateScreenshot()
void	reshape(javax.media.opengl.GLAutoDrawable canvas, int x, int y, int width, int height) Called when the GLDrawable is resized.

Constructor Detail

Renderer3d

public Renderer3d(View view)

Initialize a Renderer attached to the given View.

Renderer3d

public Renderer3d(View view,
                  boolean traceGL,
                  boolean debugGL)

Initialize a Renderer attached to the given View, and activate GL trace and errors to console.

Method Detail

dispose

public void dispose()

init

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

Called when the GLDrawable is rendered for the first time. When one calls Scene.init() function, this function is called and makes the OpenGL buffers initialization. Note: in this implementation, GL Exceptions are not triggered. To do so, make te following call at the beginning of the init() body: canvas.setGL( new DebugGL(canvas.getGL()) );

Specified by:

init in interface javax.media.opengl.GLEventListener

display

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

Called when the GLDrawable requires a rendering. All call to rendering methods should appear here.

Specified by:

display in interface javax.media.opengl.GLEventListener

reshape

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

Called when the GLDrawable is resized.

Specified by:

reshape in interface javax.media.opengl.GLEventListener

displayChanged

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

Called when the device or display mode change. Currently throw a RuntimeException: "Renderer: displayChanged not implemented.".

Specified by:

displayChanged in interface javax.media.opengl.GLEventListener

nextDisplayUpdateScreenshot

public void nextDisplayUpdateScreenshot()

getLastScreenshot

public java.awt.image.BufferedImage getLastScreenshot()

getWidth

public int getWidth()

Return the width that was given after the last resize event.

getHeight

public int getHeight()

Return the height that was given after the last resize event.
