Class Graph

  org.jzy3d.plot3d.rendering.scene.Graph

public class Graph
extends java.lang.Object

The scene's Graph basically allows decomposing the list of object into a list of AbstractDrawables primitive (i.e. objects that are not AbstractComposite. The list of primitives is ordered using either the provided DefaultOrderingStrategy or an other specified AbstractOrderingStrategy. Sorting is usefull for handling transparency properly. The Graph maintains a reference to its mother Scene in order to inform the Views when its content has change and that repainting is required. The add() method allows adding a AbstractDrawable to the scene Graph and updates all views' viewpoint in order to target the center of the scene.

add

public void add(AbstractDrawable drawable,
                boolean updateViews)

Add a Drawable to the SceneGraph and call all views' so that they update their bounds according to their mode (automatic or manual).

Parameters:

drawable: - The drawable that must be added to the scene graph.

update: - should be true if you wish to have all the views updated with old bounds including drawable bounds

add

public void add(AbstractDrawable drawable)

add

public void add(java.util.List<? extends AbstractDrawable> drawables,
                boolean updateViews)

add

public void add(java.util.List<? extends AbstractDrawable> drawables)

remove

public boolean remove(AbstractDrawable drawable,
                      boolean updateViews)

Delete a Drawable from the SceneGraph and update all views' viewpoint in order to target the center of the scene.

Parameters:

drawable - The drawable that must be deleted from the scene graph.

remove

public boolean remove(AbstractDrawable drawable)

getAll

public java.util.List<AbstractDrawable> getAll()

init

public void init(javax.media.opengl.GL gl)

                 Camera camera)

Decompose all AbstractComposite objects, and sort the extracted monotype (i.e. non-AbstractComposite AbstractDrawables) in order to render them according to the default -or defined- AbstractOrderingStrategy.

select

public void select(javax.media.opengl.GL gl,
                   javax.media.opengl.glu.GLU glu,
