DoFrame(3D)

NAME
DoFrame - Create a frame object

SYNOPSIS
C:
DtObject DoFrame()

FORTRAN:
INTEGER*4 DOFR()

DESCRIPTION
DoFrame creates a new frame organizational object. A frame is an object that describes an image to be displayed on a device. It defines a device independent 3D local coordinate system within which one or more views can be positioned.

A frame can be displayed on 0 or more devices using the function DdSetFrame <DDSF>. The frame is mapped onto the largest right rectangular volume that can fit within the device viewport such that the aspect ratio in X and Y is preserved and that the Z extent of the frame is mapped to the entire Z extent of the device. When this mapping is performed, there may be extra white space inside the device viewport. The function DfSetJust <DFSJ> is used to position this white space. A frame's volume can be specified by DfSetBoundary <DFSB> and queried with DfInqBoundary <DFQB>.

DEFAULTS

The frame extends from (0.0, 0.0, 0.0) to (1.0, 1.0, 1.0).
