PERS                                                Menu: SCRN / (SOLID) SLUTL
==============================================================================
Activates the perspective view mode.
(A nested command in geometric module only.)

Description

This command activates the perspective view mode.  The letter "P"
(perspective) or "L" (parallel) at the top of the screen indicates the
currently active mode.

If you are currently in the geometric module, or in any of the display modes
set by the \dsmod command in the solid module, the screen will be redrawn in
the appropriate display mode.

If you are in the solid module and the display mode is currently "off", the
new view will not be displayed until a new display mode is specified, enabling
you to execute a series of manipulations before the screen is redrawn.

To activate the parallel view, you may use the \npers command.

If you wish to adjust the sight cone angle use the \pcone command.

NOTE: You may toggle between perspective and parallel modes by pressing Alt+P
or using the command \onofp.
