Begins or ends interpretation of vertex subroutines as points.
FORTRAN (libfgl.a)
void bgnpoint( )
void endpoint( )
SUBROUTINE BGNPOI
SUBROUTINE ENDPOI
The bgnpoint subroutine marks the beginning of a list of vertex (begin-end style) subroutines to interpret as points. Use the endpoint subroutine to mark the end of the list. For each vertex, the system draws a one-pixel point into the frame buffer. After the endpoint subroutine completes, the current graphics position is undefined. Use the v subroutine to specify a vertex.
Between the bgnpoint and endpoint subroutines, you can issue only the following Graphics Library subroutines:
Use the lmbind and lmdef subroutines to respecify only materials and their properties.
This subroutine is part of GL in the AIXwindows Environment/6000 Version 1, Release 2 with AIXwindows/3D Feature.
The POWER Gt4 and POWER Gt4xThe POWER Gt4, POWER Gt4x, and POWER GXT1000 adapters support an arbitrary number of vertices between the bgnpoint and endpoint subroutines.
The POWERgraphics GTO and the 3D Color Graphics Processor support a maximum of 255 vertices between the bgnpoint and endpoint subroutines.
