NAME
       v_print2,  v_print3,  m_print2,	m_print3,  v_scan2,  v_scan3,  v_inters2, v_dupl2, v_dupl3, m_dupl2,  m_dupl3 - additional 3d graphics and
       associated matrix and vector routines

SYNOPSIS
       #include <graphadd.h>

       void	 v_print2(hvec2_t vec, const char *name)

       void	 v_print3(hvec3_t vec, const char *name)

       void	 m_print2(hmat2_t mat, const char *name)

       void	 m_print3(hmat3_t mat, const char *name)

       int v_scan2(hvec2_t &vec)

       int v_scan3(hvec3_t &vec)

       int v_inters2(
       const hvec2_t &p1, const hvec2_t &p2, const hvec2_t &q1,
       const hvec2_t &q2, hvec2_t *S1, hvec2_t *S2)

       void v_dupl2(hvec2_t *, hvec2_t *)

       void v_dupl3(hvec3_t *, hvec3_t *)

       void m_dupl2(hmat2_t *, hmat2_t *)

       void m_dupl3(hmat3_t *, hmat3_t *)

DESCRIPTION
       These routines ar an addition to grapmat(3). The *print routines print the approriate data to stderr.  The *scan routines read from  stdin.
       The  *dupl routines copy data. v_inters2 returns the intersection point of p1,p2 and q1,q2 in S1 and S2. The return value is 0 if no inter-
       section point is found, 1 if there is an intersection point, and two if the two lines do overlap. In that case,	the  two  points  are  the
       extrema.

NAMES
       Naming conventions as in graphmat(3).

USAGE
       All  the "functions" may have been implemented as macro's, so you can't take the address of a function. It is however guaranteed that argu-
       ments of each function/macro will be evaluated only once, except for the result argument, which can be evaluated multiple times.

SEE ALSO
       graphmat(3), graphmat++(3), Graphics and matrix routines.

NOTE
       Only available in C++ and ANSI C. v_inters2 only in C++.  Library file is /usr/local/lib/libgraphmat.a and the C++ util files.
