[vtkusers] Human Natural Bone and Skin shoule be viewed in 3d

[Gururajan.R]

All,

have to apply humans natural  bone & skin color as Habib skull diagram,

Plase have attached as reference.

i have pasted Abdomen image which i  generated  using reading CT 2d
slices dicom image.

Please any one can share me the way where i have to make the change.


Thanks
Guru
My Code below

package in.raster.viewer.component;

//Using Imagewriter to make .raw file and using volume16reader to read
.raw file
//then convert files into .vtk file

import in.raster.viewer.component.VolumeRenderWithBoxWidget.MyVtkCanvas;

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import vtk.*;
