.SH DESCRIPTION
|
|
|
|
|
.I Ico
|
|
|
|
|
displays a wire-frame rotating polyhedron, with hidden lines removed,
|
|
|
|
|
or a solid-fill polyhedron with hidden faces removed.
|
|
|
|
|
There are a number of different polyhedra available;
|
|
|
|
|
adding a new polyhedron to the program is quite simple.
|
|
|
|
|
.SH OPTIONS
|
|
|
|
|
.TP
|
|
|
|
|
.B -r
|
|
|
|
|
Display on the root window instead of creating a new window.
|
|
|
|
|
.TP
|
|
|
|
|
.B -d pattern
|
|
|
|
|
Specify a bit pattern for drawing dashed lines for wire frames.
|
|
|
|
|
.TP
|
|
|
|
|
.B -i
|
|
|
|
|
Use inverted colors for wire frames.
|
|
|
|
|
.TP
|
|
|
|
|
.B -dbl
|
|
|
|
|
Use double buffering on the display.
|
|
|
|
|
This works for either wire frame or solid fill drawings.
|
|
|
|
|
For solid fill drawings, using this switch results in substantially
|
|
|
|
|
smoother movement.
|
|
|
|
|
Note that this requires twice as many bit planes as without double buffering.
|
|
|
|
|
Since some colors are typically allocated by other programs,
|
|
|
|
|
most eight-bit-plane displays will probably be limited to eight colors
|
|
|
|
|
when using double buffering.
|
|
|
|
|
.TP
|
|
|
|
|
.B -faces
|
|
|
|
|
Draw filled faces instead of wire frames.
|
|
|
|
|
.TP
|
|
|
|
|
.B -noedges
|
|
|
|
|
Don't draw the wire frames.
|
|
|
|
|
Typically used only when -faces is used.
|
|
|
|
|
.TP
|
|
|
|
|
.B -sleep \fIn\fP
|
|
|
|
|
Sleep n seconds between each move of the object.
|
|
|
|
|
.TP
|
|
|
|
|
.B -obj \fIobject\fP
|
|
|
|
|
Specify what object to draw.
|
|
|
|
|
If no object is specified, an icosahedron is drawn.
|
|
|
|
|
.TP
|
|
|
|
|
.B -objhelp
|
|
|
|
|
Print out a list of the available objects, along with information
|
|
|
|
|
about each object.
|
|
|
|
|
.TP
|
|
|
|
|
.B -colors \fIcolor color ...\fP
|
|
|
|
|
Specify what colors should be used to draw the filled faces of the object.
|
|
|
|
|
If less colors than faces are given, the colors are reused.

|
.TP
|
|
|
|
|
.B -version
|
|
|
|
|
Print program version information and exit.

.SH PROGRAM TERMINATION
|
|
|
|
|
.LP
|
|
|
|
|
Pressing "q" will close a window. If compiled with threads support, the
|
|
|
|
|
program will stop only when all threads terminate. You can also close an
|
|
|
|
|
animation window using the ICCCM \fIdelete\fP message (depending on your
|
|
|
|
|
window manager, you will have a decoration button or menu to send such
|
|
|
|
|
message).
|
|
|
|
|
.SH ADDING POLYHEDRA
|
|
|
|
|
.LP
|
|
|
|
|
If you have the source to ico, it is very easy to add more polyhedra.
|
|
|
|
|
Each polyhedron is defined in an include file by the name of objXXX.h,
|
|
|
|
|
where XXX is something related to the name of the polyhedron.
|
|
|
|
|
The format of the include file is defined in the file polyinfo.h.
|
|
|
|
|
Look at the file objcube.h to see what the exact format of an objXXX.h
|
|
|
|
|
file should be, then create your objXXX.h file in that format.
|
|
|
|
|
.LP
|
|
|
|
|
After making the new objXXX.h file (or copying in a new one from elsewhere),
|
|
|
|
|
simply do a 'make depend'.
|
|
|
|
|
This will recreate the file allobjs.h, which lists all of the objXXX.h
|
|
|
|
|
files.
|
|
|
|
|
Doing a 'make' after this will rebuild ico with the new object information.

.SH BUGS
|
|
|
|
|
.LP
|
|
|
|
|
Pyramids and tetrahedrons with filled faces do not display correctly.
|
|
|
|
|
.LP
|
|
|
|
|
A separate color cell is allocated for each name in the -colors list, even
|
|
|
|
|
when the same name may be specified twice. Color allocation fails in
|
|
|
|
|
TrueColor displays and option \fI-faces\fP does not work well.
