A per-vertex wall-thickness field to add with
Scene.addThicknessField: the distance to the opposite surface
along each vertex's smooth normal, in world units (the placement's scale
applied, so scaled meshes read scaled).
Vertices whose rays escape in both directions (open sheets, the rims of
open meshes), dead slots and unused vertices hold NaN; hits beyond
maxDistance hold Infinity. Colour it like any field: NaN takes the
rule's nan colour, Infinity follows above.
