#if !defined( PG3D_INCLUDED ) /* Include this file only once */
#define PG3D_INCLUDED
/*
*+
* Name:
* pg3d.h
* Type:
* C include file.
* Purpose:
* Define the interface to the pg3d module
* Invocation:
* #include "pg3d.h"
* Description:
* This include file defines the interface to the pg3d module
* (implemented in file grf3d_pgplot.c) and provides the type
* definitions, function prototypes and macros, etc. needed to
* use this module.
*
* The functions in the pg3d interface provide control of the view
* of the 3D world coordinate system visible on the 2D PGPLOT
* viewport. They are provided for users of the PGPLOT implementation
* of the grf3D interface distributed with AST. No calls to these
* functions are made from within AST itself.
