Convolution of triangle meshes

[Dickinson, John]

I need to expand a triangle mesh before doing intersection checks to ensure
minimum separation distances between objects.

The operation in image processing on a 2D grid would be known as
convolution.  Has work been done on this in 3D for free-form surfaces
described by triangular meshes?

I'll take any references people have even if it doesn't directly apply to
meshed surfaces.
