The Routines

The list below enumerates the Display List routines that directly cause parts, or all, of a display list to be drawn. The refresh... routines cause the image in a device-dependent display list to be dumped to the associated device, while the display... routines cause the image in a device-independent display list to be dumped to whatever display device is specified in that call. The ...traversal... calls deal with limiting the segment calling depth within a particular traversal.

For Device-Dependent Display Lists:
refresh_segment
Draws the specified segment network on the graphics display device associated with the display list.
refresh_segment_hsr
Draws the specified segment network on the graphics display device associated with the display list with hidden surfaces removed.
refresh_element
Draws the current element of the open segment on the graphics display device associated with the display list.
traversal_lock
Controls display locking during display list traversal.
For Device-Independent Display Lists:
display_segment
Draws the specified segment network on the specified graphics display device.
display_segment_hsr
Draws the specified segment network on the specified graphics display device with hidden surfaces removed.
display_element
Draws the current element of the open segment on the specified graphics display device.
For All Display Lists:
ele_control
Control the visibility/pickability of individual elements.
inq_traversal_depth
Returns the maximum traversal depth for a display list.
seg_control
Control the visibility, pickability, and/or highlighting of entire segments.
set_traversal_depth
Defines the maximum traversal depth for a display list.
set_disp_traversal_control
Inserts a display traversal control element into the open segment.
set_pick_traversal_control
Inserts a pick traversal control element into the open segment.

The state of Starbase after a traversal depends on the contents of the display list; e.g., whether or not the Starbase state was saved/restored around segment calls, etc.

See also Chapter 8 “Filters and Name Sets” for more information on rendering objects invisible, unpickable, or highlighted.
