[vtkusers] x-ray effect in volume rendering

[Rocco Gasteiger]

Hello,

Yes, you can! ;-)

It is quite simply. In your composite function accumulate all sampled scalar
values (or opacity values) on your ray and divide it by
numSteps*globalMaximumScalarValue at the end (to get the average between 0
and 1). I've implement it and it should work.

Best regards, Rocco

Subject: [vtkusers] x-ray effect in volume rendering


Is there a way that i can achieve an x-ray effect in volume rendering of
DICOM images?
I want to see the constructed volume as a 2D xray-like "image".

I've tied the composite function combined with some tranfer and color
functions, but i didn't take the exact x-ray effect. The images i use are of
short type.
