public class VJClassifierGradientCT

extends VJClassifierLNotIndex0

This class implements the Gradient classification function with indexing for CT scans optimized.

 Index = 0 is invisible.
 Index = 128 semi-transparent blue.
 Index = 255 white.

Method Detail

alphacolor

public VJAlphaColor alphacolor(VJValue v,
                               VJGradient g)

Classify the (interpolated) voxel value and gradient magnitude into a alpha and rgb-value. Index 0 is not visible, index 128 is semi-transparent.

Overrides:

alphacolor in class VJClassifierLevoy

Parameters:

vvalue - the Integer the interpolated value at this location.

g - the gradient at this location

defaultLUT

protected void defaultLUT()

Fill the lut if not initialised from elsewhere. First entry is not shown, next entry (1) is white. Rest is filled with a spectrum.

Overrides:

defaultLUT in class VJClassifierLNotIndex0

toLongString

public java.lang.String toLongString()

Description copied from class: VJClassifier

This method can be overloaded as necessary

Overrides:

toLongString in class VJClassifierLNotIndex0
