<br>
Try this code... It works fine for me...<br>
<br>
<code><br>
private void DisplaySurface(int val, double opacityValue, double
redValue, double greenValue, double blueValue) {<br>
reader = new vtkDICOMImageReader();<br>
if (new File(directoryName).isDirectory()) {<br>
reader.SetDirectoryName(directoryName);<br>
reader.Update();<br>
} else {<br>
LOG.log(Level.WARNING, "Please select a directory");<br>
}<br>
reader.GetOutput().ReleaseDataFlagOn();<br>
<br>
// For Outline...<br>
vtkOutlineFilter outline = new vtkOutlineFilter();<br>
outline.SetInput(reader.GetOutput());<br>
<br>
vtkPolyDataMapper outlineMapper = new vtkPolyDataMapper();<br>
outlineMapper.SetInput(outline.GetOutput());<br>
<br>
vtkActor outlineActor = new vtkActor();<br>
outlineActor.SetMapper(outlineMapper);<br>
<br>
mCube = new vtkMarchingCubes();<br>
mCube.SetInput(reader.GetOutput());<br>
mCube.SetValue(0, val);<br>
mCube.ComputeNormalsOn();<br>
mCube.ComputeGradientsOff();<br>
mCube.UpdateWholeExtent();<br>
<br>
vtkPolyDataMapper pdMapper = new vtkPolyDataMapper();<br>
pdMapper.SetInput(mCube.GetOutput());<br>
pdMapper.ImmediateModeRenderingOn();<br>
pdMapper.ScalarVisibilityOff();<br>
<br>
// Create and Add Surface Actor...<br>
vtkActor actor = new vtkActor();<br>
actor.GetProperty().SetOpacity(opacityValue);<br>
actor.GetProperty().SetColor(redValue, greenValue,
blueValue);<br>
actor.SetMapper(pdMapper);<br>
<br>
vtkCanvas vpanSurface = new vtkCanvas();<br>
vpanSurface.GetRenderer().AddActor(actor);<br>
vpanSurface.GetRenderWindow().StereoCapableWindowOn();<br>
//vpanSurface.GetRenderWindow().SetStereoTypeToAnaglyph();<br>
vpanSurface.GetRenderWindow().SetStereoTypeToCrystalEyes();<br>
vpanSurface.GetRenderWindow().SetStereoRender(1); <br>
vpanSurface.GetRenderWindow().AddRenderer(vpanSurface.GetRenderer());<br>
<br>
// Add the outline actor to the renderer and size...<br>
// Here pnlSurfaceViewer is a JPanel...<br>
vpanSurface.GetRenderer().AddActor(outlineActor);<br>
vpanSurface.GetRenderer().ResetCamera();<br>
pnlSurfaceViewer.add(vpanSurface);<br>
pnlSurfaceViewer.setVisible(true);<br>

<div>Hi<br>
<br>
Change the value in following line.<br>
surface->SetValue(0, 5); <br>
<br>
Instead of 5 you can use 500 (Bone) or -500 (Skin).<br>
<br>
That is, try either <b>surface->SetValue(0, 500);</b>
or <b>surface->SetValue(0, -500); </b><br>
