Package org.jzy3d.plot3d.rendering.view

Class NativeRenderer

java.lang.Object

org.jzy3d.plot3d.rendering.view.NativeRenderer

All Implemented Interfaces:

Renderer

public class NativeRenderer
extends Object
implements Renderer

The NativeRenderer object is a GLEventListener, that makes openGL calls necessary to initialize and render a Scene for an ICanvas. One can activate OpenGl errors in console by setting debugGL to true in the constructor One can activate OpenGl feedback in console by setting traceGL to true in the constructor

Constructor Details

NativeRenderer

public NativeRenderer(View view)

Initialize a Renderer attached to the given View.

NativeRenderer

public NativeRenderer()

NativeRenderer

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

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

Method Details

init

public void init(ICanvas canvas)

Called when the GLAutoDrawable 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 Renderer

display

public void display(ICanvas canvas)

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

Specified by:

display in interface Renderer

reshape

public void reshape(ICanvas canvas,
 int x,
 int y,
 int width,
 int height)

Called when the GLAutoDrawable is resized.

Specified by:

reshape in interface Renderer

updatePainterWithGL

protected void updatePainterWithGL(com.jogamp.opengl.GLAutoDrawable canvas)

This method allows configuring the IPainter with the current GL context provided by the GLAutoDrawable. This may be usefull to override in case of a mocking GL (to avoid having the mock replaced by a real GL Context).

Parameters:

canvas -

dispose

public void dispose(ICanvas canvas)

Specified by:

dispose in interface Renderer

nextDisplayUpdateScreenshot

public void nextDisplayUpdateScreenshot()

getLastScreenshot

public com.jogamp.opengl.util.texture.TextureData 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.
