pmv(3G)

NAME
     pmv, pmvi, pmvs, pmv2, pmv2i, pmv2s - specifies the first point of a
     polygon

FORTRAN 77 SPECIFICATION
     subroutine pmv(x, y, z)
     real x, y, z

     subroutine pmvi(x, y, z)
     integer*4 x, y, z

     subroutine pmvs(x, y, z)
     integer*2 x, y, z

     subroutine pmv2(x, y)
     real x, y

     subroutine pmv2i(x, y)
     integer*4 x, y

     subroutine pmv2s(x, y)
     integer*2 x, y

     All of the above routines are functionally the same.  They differ only in
     the type declarations of their parameters and in whether or not they
     assume a two-dimensional or three-dimensional space.

PARAMETERS
     x   expects the x coordinate of the first point if a polygon.

     y   expects the y coordinate of the first point of a polygon.

     z   expects the z coordinate of the first point of a polygon.

DESCRIPTION
     pmv specifies the starting point of a polygon.  The next drawing command
     will start drawing from this point.  You draw a typical polygon with a
     pmv, a sequence of pdr, and close it with a pclos.

     Between pmv and pclos, you can only issue the following Graphics Library
     subroutines:  color, RGBcol, cpack, lmdef, lmbind pdr, c family of
     subroutines (for example, c3f), n family of subroutines (for example,
     n3f), and v family of subroutines (for example, v3f).  Only use lmdef and
     lmbind to respecify materials and their properties.

EXAMPLE
     The following sequence draws a square:
          call pmv(0.0, 0.0, 0.0)
          call pdr(1.0, 0.0, 0.0)
          call pdr(1.0, 1.0, 0.0)
          call pdr(0.0, 1.0, 0.0)
          call pclos


SEE ALSO
     bgnpol, endpol, pclos, pdr, v

NOTES
     pmv should not be used in new development.  Rather, polygons should be
     drawn using the high-performance v commands, surrounded by calls to
     bgnpol and endpol.

     There can be no more than 256 vertices in a polygon.  Therefore, there
     can be no more than 255 pdr calls between pmv and pclos.
