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.*;

Hi All,
 
I created a 3D of the skull from CT 2d slices, I want to select a part
of the skull and delete it , as example kindly find attached image , how
to implement that please
I tried clipping, but not work as I wish
 
 
best regards
