public class OFClassifierScintillansIxLT0
extends OFClassifierScintillans

This class implements a classification function of 3D optical flows that sets a scintillation corresponding in size, color and direction to the flow vector. Only if a surface is present at the location, will the static underlying volume be shown.

 This classifier supports indexing:
 index = 0: flow not shown, static surface may be shown by secondary classifier.
 index >= 1: flow vector shown (if > 0.05)
 The opacity is set to the magnitude of the flow vector.
 This classifier can show the static underlying volume.

Constructor Detail

OFClassifierScintillansIxLT0

public OFClassifierScintillansIxLT0()
Method Detail

toString

public java.lang.String toString()
Description copied from class: VJClassifier
Return a String with information of this classifier.
Overrides:
toString in class OFClassifierScintillans

doesIndex

public boolean doesIndex()
Description copied from class: VJClassifier
Tell renderer whether this classifier can process indices in the voxel value.
Overrides:
doesIndex in class OFClassifierScintillans

visible

public boolean visible(FlowJValue value)

alphacolor

public VJAlphaColor alphacolor(FlowJValue value,
                               VJGradient g)
Classify a flow based on the flow vector, and whether or not a static voxel is present, into a VJAlphaColor. Works only with indexed static volumes.
 if the index at vl == 0 the static volume is shown (making use of the index).
Overrides:
alphacolor in class OFClassifierScintillans
Parameters:
value - a FlowJValue containing the flow vector, the index and the voxel value, if any.
g - a VJGradient containing the voxels gradient.
