Functions
uint32_t	reusex::pipeline::morton_tile_sort_key (float x, float y, float z, const float lo[3], const float range[3])
	30-bit bit-reversed Morton sort key of (x, y, z) quantised to 10 bits per axis over the box starting at lo with extent range (each > 0).
std::vector< uint8_t >	reusex::pipeline::compute_tile_index (const ProjectDB &db, std::string_view name, uint32_t tile_bits=6)
	Compute the spatial tile index for a morton_10bit_bitrev cloud.
std::pair< TileIndexHeader, std::vector< TileInfo > >	reusex::pipeline::parse_tile_index (const std::vector< uint8_t > &blob)
	Deserialize the header + tile array from a tile index blob.
std::size_t	reusex::pipeline::build_tile_index (ProjectDB &db, std::string_view name)
	Build and store the tile index of cloud name when it is Morton-ordered.

Variables
constexpr uint32_t	reusex::pipeline::kTileIndexMagic = 0x52555854u
	Magic number identifying a tile index blob.
constexpr std::string_view	reusex::pipeline::kMortonStorageOrder = "morton_10bit_bitrev"
	The storage order a cloud must have for a tile index to make sense.
