BKE_mesh_remap_calc_difference_from_mesh()

float BKE_mesh_remap_calc_difference_from_mesh	(	const SpaceTransform *	space_transform,
		blender::Span< blender::float3 >	vert_positions_dst,
		const Mesh *	me_src )

Compute a value of the difference between both given meshes. The smaller the result, the better the match.

We return the inverse of the average of the inversed shortest distance from each dst vertex to src ones. In other words, beyond a certain (relatively small) distance, all differences have more or less the same weight in final result, which allows to reduce influence of a few high differences, in favor of a global good matching.
