Parametric color map corresponding to particular morphology

Is it possible to define a parametric color map where the color is defined by the morphology of a particular slice?

You can define and display any parametric color maps.

@hherhold

For example, say you wanted to display lung tracheae or blood vessels, and display those with a larger cross-sectional area as blue, and those with smaller area as red?

This one should be easy. See steps described here. You can also use SlicerVMTK extension to extract centerline curve and get radius at each centerline point.

If you want to extract part of a model corresponding to a certain radius range, then you can apply vtkThreshold filter to the model (see example here).
