public class OFClassifierScintillansIx255

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 or 255: flow vector shown (if random value greater than preset value)


See Also: 
index > 0 < 255: static volume shown (depending on static classifier).

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)

Tell calling program whether this voxel has an interesting index (worthy to do interpolation and gradient calcs on)

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 or 255, a random subset of the flows is displayed as a scintillation
 if the 1 <= index < 255, 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.
