  visad.DataRenderer
      visad.java3d.RendererJ3D

All Implemented Interfaces:

Cloneable

Direct Known Subclasses:

DefaultRendererJ3D, DirectManipulationRendererJ3D

public abstract class RendererJ3D
extends DataRenderer

RendererJ3D is the VisAD abstract super-class for graphics rendering algorithms under Java3D. These transform Data objects into 3-D (or 2-D) depictions in a Display window.

RendererJ3D is not Serializable and should not be copied between JVMs.

Method Summary

void	clearBranch() clear part of Display scene graph generated by this DataRenderer
void	clearScene() clear any scene graph created by this DataRenderer, and clear all instance variables
boolean	doAction() re-transform if needed; return false if not done
abstract BranchGroup	doTransform() create a BranchGroup scene graph for Data in links; this can put Behavior objects in the scene graph for DataRenderer classes that implement direct manipulation widgets; may reduce work by only changing scene graph for Data and Controls that have changed: 1. use boolean[] changed to determine which Data objects have changed 2. if Data has not changed, then use Control.checkTicks loop like in prepareAction to determine which Control-s have changed
void	flush(Group branch)
BranchGroup	getBranch()
ShadowType	makeShadowFunctionType(FunctionType type, DataDisplayLink link, ShadowType parent) factory method for constructing a subclass of ShadowType appropriate for the graphics API, that also adapts ShadowFunctionType; ShadowType trees are constructed that 'shadow' the MathType trees of Data to be depicted, via recursive calls to buildShadowType() methods of MathType sub-classes, to DataRenderer.makeShadow*Type() methods, to Shadow*Type constructors, then back to buildShadowType() methods; the recursive call chain is initiated by DataDisplayLink.prepareData() calls to buildShadowType() methods of MathType sub-classes;
