/*
 * vec.h --  Vector macros for 2,3, and 4 dimensions,
 *           for any  combination of C scalar types.
 *
 * Author:		Don Hatch (hatch@sgi.com)
 * Last modified:	Fri Sep 30 03:23:02 PDT 1994
 *
 * General description:
 *
 *	The macro name describes its arguments; e.g.
 *	    	MXS3 is "matrix times scalar in 3 dimensions";
 *	    	VMV2 is "vector minus vector in 2 dimensions".
 *
 *	If the result of an operation is a scalar, then the macro "returns"
 *	the value; e.g.
 *	    	result = DOT3(v,w);
 *	    	result = DET4(m);
 *
 *	If the result of an operation is a vector or matrix, then
 *	the first argument is the destination; e.g.
 *	    	SET2(tovec, fromvec);
 *	    	MXM3(result, m1, m2);
 *
 *  WARNING: For the operations that are not done "componentwise"
 *	    (e.g. vector cross products and matrix multiplies)
 *	    the destination should not be either of the arguments,
 *	    for obvious reasons.  For example, the following is wrong:
 *		VXM2(v,v,m);
 *          For such "unsafe" macros, there are safe versions provided,
 *          but you have to specify a type for the temporary
 *	    result vector or matrix.  For example, the safe versions
 *	    of VXM2 are:
 *              VXM2d(v,v,m)    if v's scalar type is double or float
 *              VXM2i(v,v,m)    if v's scalar type is int or char
 *              VXM2l(v,v,m)    if v's scalar type is long
 *              VXM2r(v,v,m)    if v's scalar type is real
 *              VXM2safe(type,v,v,m) for other scalar types.
 *	    These "safe" macros do not evaluate to C expressions
 *	    (so, for example, they can't be used inside the parentheses of
 *	    a for(...)).
 *
 *  Specific descriptions:
 *
 *	The "?"'s in the following can be 2, 3, or 4.
 *
 *	SET?(to,from)			to = from
 *	SETMAT?(to,from)		to = from
 *	ROUNDVEC?(to,from)		to = from with entries rounded
 *							to nearest integer
 *	ROUNDMAT?(to,from)		to = from with entries rounded
 *							to nearest integer
 *	FILLVEC?(v,s)			set each entry of vector v to be s
 *	FILLMAT?(m,s)			set each entry of matrix m to be s
 *	ZEROVEC?(v)			v = 0
 *	ISZEROVEC?(v)			v == 0
 *	EQVEC?(v,w)			v == w
 *	EQMAT?(m1,m2)			m1 == m2
 *	ZEROMAT?(m)			m = 0
 *	IDENTMAT?(m)			m = 1
 *	TRANSPOSE?(to,from)		(matrix to) = (transpose of matrix from)
 *	ADJOINT?(to,from)		(matrix to) = (adjoint of matrix from)
 *					 i.e. its determinant times its inverse
 *
 *	V{P,M}V?(to,v,w)		to = v {+,-} w
 *	M{P,M}M?(to,m1,m2)		to = m1 {+,-} m2
 *	SX{V,M}?(to,s,from)		to = s * from
 *	M{V,M}?(to,from)		to = -from
 *	{V,M}{X,D}S?(to,from,s)		to = from {*,/} s
 *	MXM?(to,m1,m2)			to = m1 * m2
 *	VXM?(to,v,m)			(row vec to) = (row vec v) * m
 *	MXV?(to,m,v)			(column vec to) = m * (column vec v)
 *	LERP?(to,v0,v1,t)		to = v0 + t*(v1-v0)
 *
 *	DET?(m)				determinant of m
 *	TRACE?(m)			trace (sum of diagonal entries) of m
 *	DOT?(v,w)			dot (scalar) product of v and w
 *	NORMSQRD?(v)			square of |v|
 *	DISTSQRD?(v,w)			square of |v-w|
 *
 *	XV2(to,v)			to = v rotated by 90 degrees
 *	VXV3(to,v1,v2)			to = cross (vector) product of v1 and v2
 *	VXVXV4(to,v1,v2,v3)		to = 4-dimensional vector cross product
 *					 of v1,v2,v3 (a vector orthogonal to
 *					 v1,v2,v3 whose length equals the
 *					 volume of the spanned parallelotope)
 *	VXV2(v0,v1)			determinant of matrix with rows v0,v1
 *	VXVXV3(v0,v1,v2)		determinant of matrix with rows v0,v1,v2
 *	VXVXVXV4(v0,v1,v2,v3)		determinant of matrix with rows v0,..,v3
 *
 *   The following macros mix objects from different dimensions.
 *   For example, V3XM4 would be used to apply a composite
 *   4x4 rotation-and-translation matrix to a 3d vector.
 *
 *	SET3from2(to,from,pad)		(3d vec to) = (2d vec from) with pad
 *	SET4from3(to,from,pad)		(4d vec to) = (3d vec from) with pad
 *	SETMAT3from2(to,from,pad0,pad1) (3x3 mat to) = (2x2 mat from)
 *					 padded with pad0 on the sides
 *					 and pad1 in the corner
 *	SETMAT4from3(to,from,pad0,pad1) (4x4 mat to) = (3x3 mat from)
 *					 padded with pad0 on the sides
 *					 and pad1 in the corner
 *	V2XM3(to2,v2,m3)       (2d row vec to2) = (2d row vec v2) * (3x3 mat m3)
 *	V3XM4(to3,v3,m4)       (3d row vec to3) = (3d row vec v2) * (4x4 mat m4)
 *	M3XV2(to2,m3,v2)       (2d col vec to2) = (3x3 mat m3) * (2d col vec v2)
 *	M4XV3(to3,m4,v3)       (3d col vec to3) = (4x4 mat m4) * (3d col vec v3)
 *	M2XM3(to3,m2,m3)       (3x3 mat to3) = (2x2 mat m2) * (3x3 mat m3)
 *	M3XM4(to4,m3,m4)       (4x4 mat to4) = (3x3 mat m3) * (4x4 mat m4)
 *	M3XM2(to3,m3,m2)       (3x3 mat to3) = (3x3 mat m3) * (2x2 mat m2)
 *	M4XM3(to4,m4,m3)       (4x4 mat to4) = (4x4 mat m4) * (3x3 mat m3)
