cCuboid class

cCuboid offers some native support for integral-boundary cuboids. A cuboid internally consists of two Vector3i-s. By default the cuboid doesn't make any assumptions about the defining points, but for most of the operations in the cCuboid class, the p1 member variable is expected to be the minima and the p2 variable the maxima. The Sort() function guarantees this condition.

The Cuboid considers both its edges inclusive.

Member variables

Name	Type	Notes
p1	Vector3i	The first corner. Usually the lesser of the two coords in each set
p2	Vector3i	The second corner. Usually the larger of the two coords in each set

Functions

Name	Parameters	Return value	Notes
() (constructor)		cCuboid	Creates a new Cuboid object with all-zero coords
() (constructor)	OtherCuboid	cCuboid	Creates a new Cuboid object as a copy of OtherCuboid
() (constructor)	X, Y, Z	cCuboid	Creates a new Cuboid object with the specified point as both its corners (the cuboid has a size of 1 in each direction).
() (constructor)	X1, Y1, Z1, X2, Y2, Z2	cCuboid	Creates a new Cuboid object with the specified points as its corners.
() (constructor)	Point1, Point2	cCuboid	Creates a new Cuboid object with the specified points as its corners.
Assign	SrcCuboid		Copies all the coords from the src cuboid to this cuboid. Sort-state is ignored.
Assign	X1, Y1, Z1, X2, Y2, Z2		Assigns all the coords to the specified values. Sort-state is ignored.
ClampX	MinX, MaxX		Clamps both X coords into the range provided. Sortedness-agnostic.
ClampY	MinY, MaxY		Clamps both Y coords into the range provided. Sortedness-agnostic.
ClampZ	MinZ, MaxZ		Clamps both Z coords into the range provided. Sortedness-agnostic.
DifX		number	Returns the difference between the two X coords (X-size minus 1). Assumes sorted.
DifY		number	Returns the difference between the two Y coords (Y-size minus 1). Assumes sorted.
DifZ		number	Returns the difference between the two Z coords (Z-size minus 1). Assumes sorted.
DoesIntersect	OtherCuboid	bool	Returns true if this cuboid has at least one voxel in common with OtherCuboid. Note that edges are considered inclusive. Assumes both sorted.
Engulf	Point		If needed, expands the cuboid to include the specified point. Doesn't shrink. Assumes sorted.
Expand	SubMinX, AddMaxX, SubMinY, AddMaxY, SubMinZ, AddMaxZ		Expands the cuboid by the specified amount in each direction. Works on unsorted cuboids as well. NOTE: this function doesn't check for underflows.
GetVolume		number	Returns the volume of the cuboid, in blocks. Note that the volume considers both coords inclusive. Works on unsorted cuboids, too.
IsCompletelyInside	OuterCuboid	bool	Returns true if this cuboid is completely inside (in all directions) in OuterCuboid. Assumes both sorted.
IsInside	X, Y, Z	bool	Returns true if the specified point (integral coords) is inside this cuboid. Assumes sorted.
IsInside	Point	bool	Returns true if the specified point (floating-point coords) is inside this cuboid. Assumes sorted.
IsInside	Point	bool	Returns true if the specified point (integral coords) is inside this cuboid. Assumes sorted.
IsSorted		bool	Returns true if this cuboid is sorted
Move	OffsetX, OffsetY, OffsetZ		Adds the specified offsets to each respective coord, effectively moving the Cuboid. Sort-state is ignored and preserved.
Sort			Sorts the internal representation so that p1 contains the lesser coords and p2 contains the greater coords.
