Imprinting meshes onto image data
We need an aeva operation that can "splat" surface (polydata) and volume (ugrid) meshes onto a volumetric image. We will need to work with Ahmet to determine whether the "splat" should be some smooth function (i.e. distance to surface) or a label map; and whether the "splat" results in point-data or cell-data.
There are several VTK filters (vtkPolyDataDistance and related classes) that we should investigate for this.
We should also consider how we want to store provenance information (i.e., what surface was used to create the new scalar array) and how we want to present the result (i.e., is a scalar array a "component" of an image? How do we represent that in SMTK).
Because there are a lot of unknowns, the first step should be creation of a new topic on the SMTK discourse site.
