Well as I mention I am using OSX 10.9.5<br>
Graphics : Intel Iris Pro 1536 MB<br>
but I am not sure how to check is Opengl2 or Opengl1 base </blockquote><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

So *vtkProjectedTetrahedraMapper* should be the right filter?<br>
<br>
Here are part of the script i used. The input image is *UnstructuredGrid*<br>
and I map the output to a Actor. But the result was really to *laggy* can't<br>
even rotate the object.<br>
======================================<br>
vtkProjectedTetrahedraMapper volumeMapper = new<br>
vtkProjectedTetrahedraMapper();<br>
vtkVolume volume = new vtkVolume();<br>
vtkVolumeProperty volumeProperty = new vtkVolumeProperty();<br>
volumeProperty.IndependentComponentsOn();<br>
volumeProperty.DisableGradientOpacityOn();<br>
volumeProperty.SetInterpolationType(1);<br>
volumeProperty.SetShade(0);<br>
volumeProperty.SetAmbient(0.5d);<br>
volumeProperty.SetDiffuse(0.4d);<br>
volumeProperty.SetSpecular(0.4d);<br>
volumeMapper.SetInputData(image);<br>
volumeMapper.Update();<br>
======================================<br>
<br>
At the meantime, I got another question.<br>
>From paraview, we can extract color maps into .json file.<br>
Is it possible to import that to my vtk project? What class should I be<br>
using to read them or by changing lookuptable? Need some lead on that too...<br>
thx<br>
