[vtkusers] Overlay coloring (?lvaro Gonz?lez Lorente)

[S, Navneeth (GE, Research)]

You need to volume render your dataset.
See: 
http://www.vtk.org/doc/release/4.0/html/classvtkVolumeRayCastMapper.html

The red-green temperature map can be realized by adding points to the
color transfer function used in volume rendering.
http://www.vtk.org/doc/nightly/html/classvtkColorTransferFunction.html
(However the tricky bit is to find representative points on the
intensity histogram to insert these points)

Enjoy,

Hello,

I need to perform colored overlay displaying in a certain volume, and I
was wondering if anyone would know which class would help me better.
What I am exactly trying to do is to color a CT image (CT volume,
converted into VTK) with different colors, resembling a temperature map
in a certain organ (hottest spot would need to be colored in red, the
coldest one in blue, and yellow, green, orange would go in between).

If anyone knows a clever way of doing this, I would be mroe than pleased
if you let me know. 

Thanks in advance!
