DoPickID(3D)

NAME
DoPickID - Create a pick identifier object

SYNOPSIS
C:
DtObject DoPickID(pickid)
DtInt pickid;

FORTRAN:
INTEGER*4 DOPID(PICKID)
INTEGER*4 PICKID

DESCRIPTION
DoPickID returns a pick identifier primitive attribute object. The argument pickid determines the pick identification number for subsequent objects. A pick identification number is an arbitrary 32-bit value that is used to identify various parts of the Dor database. It is similar to a name set in its ability to identify or give special meaning to parts of the database.

The pick identifiers are part of the information returned in a pick. They are returned for the picked primitives as well as for their ancestors in the hierarchy.

DEFAULTS
The default DoPickID is 0.
