The graPHIGS Programming Interface: ISO PHIGS Subroutine Reference

INQUIRE MODELING CLIPPING FACILITIES (PHOP,*,*,*)

Purpose

Use Inquire Modeling Clipping Facilities to inquire the number and list of modeling clipping operators, and the number of distinct planes in the modeling clipping volume.

Although this inquiry returns two operations (REPLACE and INTERSECT) and six as the number of distinct planes in the modeling clipping volume, support differs by workstation. Therefore, use the graPHIGS API Inquire Workstation Description (GPQWDT) to inquire these values for a specific workstation.

If the inquired information is available, then the graPHIGS API sets the error indicator to zero and returns the values in the output parameters. If the inquired information is unavailable, then the values returned in the output parameters are invalid and the graPHIGS API sets the error indicator to the following error:

2
