Classes
struct	voxel::SurfaceVoxel
class	voxel::VolumeSurface
	Keyed by brick slot not pool id since uniform bricks have no pool id and shared bricks differ per instance. More...

Enumerations
enum class	VoxelClass : uint8_t {   empty = 0 , inside = 1 , face = 2 , edge = 3 ,   corner = 4 }

Functions
auto	voxel::normalIndexOf (glm::ivec3 direction) noexcept -> uint8_t
auto	voxel::normalDirection (uint8_t index) noexcept -> glm::ivec3
constexpr auto	voxel::packClassification (VoxelClass type, uint8_t normal) noexcept -> uint8_t
	Class in the low three bits and normal index in the high five.
constexpr auto	voxel::classOf (uint8_t classification) noexcept -> VoxelClass
constexpr auto	voxel::normalOf (uint8_t classification) noexcept -> uint8_t
auto	voxel::classifyFromNeighbours (bool solid_neg_x, bool solid_pos_x, bool solid_neg_y, bool solid_pos_y, bool solid_neg_z, bool solid_pos_z) noexcept -> uint8_t
	Exposed faces that cancel (one voxel thick walls) promote to corner.
constexpr auto	voxel::faceBit (int axis, bool positive) noexcept -> uint8_t
	One bit per face in the order neg x pos x neg y pos y neg z pos z.
constexpr auto	voxel::exposureMask (bool solid_neg_x, bool solid_pos_x, bool solid_neg_y, bool solid_pos_y, bool solid_neg_z, bool solid_pos_z) noexcept -> uint8_t
	A set bit is a face with an empty neighbour behind it.
void	voxel::buildBrickSurfaceInto (const BrickOccupancy &brick, const BrickNeighbourhood &neighbours, std::vector< SurfaceVoxel > &out)
auto	voxel::buildBrickSurface (const BrickOccupancy &brick, const BrickNeighbourhood &neighbours) -> std::vector< SurfaceVoxel >

Variables
constexpr uint8_t	voxel::k_normal_direction_count = 26
constexpr uint8_t	voxel::k_normal_undefined = 26
constexpr uint8_t	voxel::k_all_faces_exposed = 0x3F
