Description
This command sets a display mode while in the solid module.  The modes are: w
wire frame, h hidden lines removal, a dashed hidden lines, s colored surfaces,
d shaded surfaces and o off.

Selecting `w', `h', `a', `s' or `d' causes the model to be redrawn in the
selected display mode following every command that manipulates the eye or
target positions, such as \walk, \eye, \axo, etc.

If you select surfaces (`s') or shadows (`d'), you are asked if you want a
full screen display.  If you reply `y' to a full screen display, you are asked
for a file name of 3 characters to which the system adds -n, n being a number
from 1-999, for each picture taken using the `p' key to capture the model from
the screen.  The screen will be redrawn without the menus and command lines.
(The character `w' appears in the lower-right of the screen while the system
is working.) In order to reactivate the menus, press any key.

You are then prompted to select the type of presentation from the following
options (`c', `h', or `s').

c  the surface polygons are filled with the Color of its lines (edges).
h  The surfaces model is displayed with Hidden lines removed.
s  Each polygon appears with a different intensity of Shade related to its
   angle to the sun (depending on your monitor).

If you select the last option, `s,' you will be asked to specify the
graduation of the shading by entering a number between 4 and 12.  The default
is 7.

For all the options, if wire entities exist in the original model, you will be
asked if you wish to display them.  This process may take some time, depending
on the quantity of such entities.

If you have selected shadows (`d') in prompt1 you will be asked to enter the
height of the ground level in relation to the coordinate origin - 0 0 0; the
default is 0.  Select a point indicating the direction of the sun relative to
the origin point (0 0 0).  The default is the current location.  If you select
option, `s,' in prompt 4, you will be asked to specify the shading, `f' for
full or `g' on the ground only.  The default is `f'.

If `o' (off) is selected, you may implement a series of manipulate commands
without the screen being redrawn.  When you have completed the manipulation
you may view the result by returning to this command and activating one of the
other (`w', `h', `a', `s' or `d') display options.

The values that you have specified for the sight cone, surfaces option,
graduation of shade, sun location and height of ground level, will all be
retained by the system as default values throughout the work session or until
new values are specified.  You may change the sight cone value or the sun
location by using the \pcone and \sunpt commands respectively.

NOTE: When using options `s' or `d' for the first time on the current model,
or if the solid model has not been previously saved, the system processing may
take some time, depending on the complexity of the model.
