bgnpoint(3G)

NAME
     bgnpoint, endpoint - delimit the interpretation of vertex routines as
     points

C SPECIFICATION
     void bgnpoint()

     void endpoint()

PARAMETERS
     none

DESCRIPTION
     bgnpoint marks the beginning of a list of vertex routines that you want
     interpreted as points.  Use the endpoint 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 bgnpoint and endpoint, you can issue only the following Graphics
     Library routines: c, color, cpack, lmbind, lmcolor, lmdef, n, RGBcolor,
     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
     bgnpoint and endpoint.

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

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

NOTE
     On Impact and Infinite Reality lmcolor cannot be called between bgnpoint
     and endpoint
