[Insight-users] RayCastInterpolateImageFunction

[Markus Neuner]

Hi Juan,

you can rescale the intensities of the 3D volume before you pass it to
the RayCastInterpolateImageFunction.
Or you can use an extended framework for DRR generation which is
available at:
http://ibia.umit.at/ResearchGroup/Phil/web/Simple2D3DRegistrationFramework.html
(see source.zip in the directory DRR:
RayCastPerspectiveProjectionImageFilter). It has a built-in
Intensity-Transfer-Function support.

Regards,
Markus
