All Implemented Interfaces:

Cloneable

public class ImageRendererJ3D
extends DefaultRendererJ3D

ImageRendererJ3D is the VisAD class for fast loading of images and image sequences under Java3D. WARNING - when reUseFrames is true during doTransform() ImageRendererJ3D makes these assumptions: 1. That the images in a new time sequence are identical to any images at the same time in a previous sequence. 2. That the image sequence defines the entire animation sampling.

Method Detail

isImageType

public static boolean isImageType(MathType type)

determine whether the given MathType is usable with ImageRendererJ3D

verifyImageRendererUsable

public static void verifyImageRendererUsable(MathType type,
                             ScalarMap[] maps)
                                      throws VisADException

Deprecated. Use isRendererUsable(MathType, ScalarMap[]) instead.

Throws:

VisADException

isRendererUsable

public static boolean isRendererUsable(MathType type,
                       ScalarMap[] maps)
                                throws VisADException

determine whether the given MathType and collection of ScalarMaps meets the criteria to use ImageRendererJ3D. Throw a VisADException if ImageRenderer cannot be used, otherwise return true.

Throws:

VisADException

isByRefUsable

public static boolean isByRefUsable(DataDisplayLink link,
                    ShadowType shadow)
                             throws VisADException,
                                    RemoteException

Throws:

VisADException

RemoteException

makeShadowFunctionType

public ShadowType makeShadowFunctionType(FunctionType type,
                                DataDisplayLink link,
                                ShadowType parent)

                                         RemoteException

Description copied from class: DataRenderer

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;

Overrides:

makeShadowFunctionType in class RendererJ3D

Parameters:

type - FunctionType that returned ShadowType will shadow

link - DataDisplayLink linking Data to be depicted

parent - parent in ShadowType tree structure

Returns:

constructed ShadowType

Throws:

VisADException - a VisAD error occurred

RemoteException - an RMI error occurred

setReUseFrames

public void setReUseFrames(boolean reuse)

Toggle the re-using of frames when a new image or set of images is set in the datareference.

1. That the images in a new time sequence are identical to any images at the same time in a previous sequence.
2. That the image sequence defines the entire animation sampling.
