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.

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.
