aephysics.shape, Box3D's sphere.c, capsule.c and the geometric half of shape.c in Aether: the sphere's and capsule's mass, bounds, ray casts in the closest-point forms that keep their precision far from the origin, shape casts, overlap and mover planes; the hull's mover; and the Shape of any kind (sphere, capsule, hull, mesh, height field, the compound reserved) with its dispatch under a transform: bounds, swept and fat bounds, centroid, areas, mass, extent, ray and shape casts, overlap, the mover's planes, the proxy; and the collision filters. test_shape.ae: the reference's masses (sphere, analytic, translated, rotated and transformed boxes, the capsule bracketed by hulls), bounds, the sphere and capsule ray cases (hits, misses, clip, interior, graze, side, oblique, caps, degenerate, near parallel), the overlap convention across the solids, the far-origin precision, the cast through the dispatch; plus every kind under one transform through every query, and the filters. 440 checks. The name and flag tests need a world and come with the dynamics. bench/shape.ae against bench/shape_box3d.c: the same hits and sums on every phase; sphere rays and masses at parity, capsule rays 0.8x, the mover 1.45x, the GJK cast and overlap on proxies with radii 2-2.5x, recorded to profile.

The tenth layer: Box3D's sphere.c, capsule.c and the geometric half of shape.c as
aephysics.shape.Shapeof any kind with the dispatch under a transform:compute_shape_aabb,compute_fat_shape_aabb,compute_swept_shape_aabb,get_shape_centroid,get_shape_area,get_shape_projected_area,compute_shape_mass,compute_shape_extent,ray_cast_shape,shape_cast_shape,overlap_shape,collide_mover,make_shape_proxy;Filter/QueryFilterwithshould_shapes_collide/should_query_collide. The compound kind is reserved for the next layer.test_shape.ae: the reference's geometry subtests (the world-bound name and flag tests come with the dynamics) plus every kind under one transform through every query, and the filters. 440 checks. The far-origin table shows our doubles three orders under the reference's float floor, still hitting at ten million units.bench/shape.aevsbench/shape_box3d.c: identical hits and sums; sphere rays and masses at parity, capsule rays 0.8x, the mover 1.45x, the GJK cast and overlap with radii 2-2.5x (to profile, issue to follow).
