endpoi(3G)

NAME
     bgnpoi, endpoi - delimit the interpretation of vertex routines as points

FORTRAN 77 SPECIFICATION
     subroutine bgnpoi

     subroutine endpoi

PARAMETERS
     none

DESCRIPTION
     bgnpoi marks the beginning of a list of vertex routines that you want
     interpreted as points.  Use the endpoi routine to mark the end of the
     list.  For each vertex, the system draws a one-pixel point into the frame
     buffer.  Use the v routine to specify a vertex.

     Between bgnpoi and endpoi, you can issue only the following Graphics
     Library routines: c, color, cpack, lmbind, lmcolo, lmdef, n, RGBcol, t,
     and v.  Use lmdef and lmbind to respecify only materials and their
     properties.

     There is no limit to the number of vertices that can be specified between
     bgnpoi and endpoi.

     By default points are forced to the nearest pixel center prior to scan
     conversion.  This coercion is defeated with the subpix command.  Subpixel
     point positioning is important only when points are scan converted with
     antialiasing enabled (see pntsmo).

     After endpoi, the current graphics position is the most recent vertex.

NOTE
     On Impact and Infinite Reality lmcolo cannot be called between bgnpoi and
     endpoi
