{{documentation/{{documentation/version}}/module-section|Module Description}}
This module is used to "paint" a model with data from an image volume in Slicer. This calls vtkProbeFilter internally, which will probe (interpolate) a value from the image volume at every point location (vertex) of the model. This module works in "world space" so it handles the coordinate systems of the model (known as RAS) and volume (internally stored in an array with "ijk" coordinates in Slicer terminology).


{{documentation/{{documentation/version}}/module-section|Use Cases}}
Most frequently used for these scenarios:

* Use Case 1: Visualize data from any volume (e.g. T2 MRI) on the surface of a model (e.g. a tumor surface)
* Use Case 2: Sample data onto a model for later quantitative analysis, perhaps in another program, such as sampling FA/T2/etc. onto a model of fiber tracts
