<H3>Key description</H3>

 <P>The following are general keys (alternatives in brackets):

<UL>
<LI> Esc (Q):	quit
<LI> F1 (?):	help
<LI> Print (D):	save picture as *.ppm file
<LI> F5 F6 F7 F8:	set mode camera/object/slices/light
<LI> 1-9:	choose camera/object/slices/light
<LI> F9  F10:	load/save window status into a file *.wzwindow
<LI> F11 F12:	load/save window status for this session
<LI> KP1-KP9:	movements and rotations (depends on mode)
<LI> KP0 KP_Decimal:	changing size (depends on mode)
<LI> !:	toggle wireframe mode
<LI> #:	toggle frame
<LI> @:	toggle background (black/white)

</UL>

<A NAME="SetModeC"> <HR></A>
<H3>F5: Camera mode on</H3>

 <P>In the camera mode, the mouse and the arrow keys modify the
the current camera position (or the point of view).
 <P>There are 9 possibly different camera positions (viewports).  One
of them is the current one.  You can switch between them with the
alphanumeric keys 1-9.  If the new camera was undefined yet, it will
be created.

<A NAME="SetModeO"> <HR></A>
<H3>F6: Object mode on</H3>

 <P>In the object mode, the mouse and the arrow keys modify the
position of the object relative to the frame.  Thus, you can choose
the part of the object you want to see.
 <P>Sometimes there are several objects (for example, a geometry and a
grid). There may be up to 9 objects. One of them is the current one.
You can switch between them with the alphanumeric keys 1-9.

<A NAME="SetModeP"> <HR></A>
<H3>F7: Slice mode on</H3>

 <P>There are three orthogonal slices.  They are used to show various
intersections of the object with a plane. In the slice mode, it is
possible to modify their position relative to the frame using the
mouse and the arrow keys.
 <P>There are 9 possibly different choices of slices. One of them is
the current one.  You can switch between them with the alphanumeric
keys 1-9.  If the new set of slices was undefined yet, it will be
created.

<A NAME="SetModeL"> <HR></A>
<H3>F8: Light mode on</H3>

 <P>There are light sources.  In the light mode, it is possible to
modify their position relative to the frame using the mouse and the
arrow keys.
 <P>There are 9 possibly different light sources. One of them is the
current one.  You can switch between them with the alphanumeric keys
1-9.  If the new light source was undefined yet, it will be created.

<A NAME="SaveLoad"> <HR></A>
<H3>F9, F10, F11, F12: load and save the state of the renderer</H3>

 <P>The state of the renderer may be saved.  There are two
possibilities: 
<UL>
<LI> F12: save for the current session (load with F11);
<LI> F10: save into a file (load with F9);
</UL>

<A NAME="Print"> <HR></A>
<H3>"Print" Key (alternative: "D")</H3>

 <P>Prints the actual picture into a ppm file.

<A NAME="FrameToggle"> <HR></A>
<H3>Key #</H3>

 <P>Toggle for drawing the coordinate frame (bounding box)

<A NAME="Quit"> <HR></A>
<H3>Escape (alternative: "Q")</H3>

 <P>Quit the viewer.

<A NAME="numeric"> <HR></A>
<H3>numeric Keys (1-9)</H3>

 <P>It depends on the current mode (defined by the F5-F8 keys) what happens:  
<UL>
<LI> camera mode (F5): it defines the current camera position;
<LI> object mode (F6): it defines the current object;
<LI> slice  mode (F7): it defines the current choice of slices;
<LI> light  mode (F8): it defines the current light position;
</UL>

<A NAME="Background"> <HR></A>
<H3>Key @</H3>

 <P>Toggle the background color (black/white)

<A NAME="mouse"> <HR></A>
<H3>Mouse sensitivity: + resp. -</H3>

 <P> The "+" key increases mouse sensitivity.
 <BR>The "-" key decreases mouse sensitivity.

<A NAME="Wireframe"> <HR></A>
<H3>Key !</H3>

 <P>toggle wireframe mode

<A NAME="Gouraud"> <HR></A>
<H3>Key</H3>

 <P>toggle Gouraud/flat shading
