Sample retessellated meshes for (a-c) a square-aperture wide-field source outside of a complex mouse atlas, and (d-f) a circular-aperture wide-field source with a square-shaped camera detector for an adult head model, where (a,d) show the object mesh before retessellation, (b,e) show the mesh after retessellation, and (c,f) show cross-cut views of the final meshes Notations: S – source domain; M – original object mesh; O – circumscribed circle of S; S’ – circumscribed triangle of S; C – convex hull of all nodes in M and S’; T – extended mesh bounded by C and the exterior surface of M; M’ – the final mesh after merging T with M; E₀ – photon-launching element; D – a wide-field detector.
