bzlogo - convert SGI images to the logo format for bz
bzlogo imgfile logofile [ -left | -right ] [ stepsize ]
Bzlogo converts an SGI RGB image file to a format that bz(6D) can load.
The stepsize option allows some control over the refinement of the
result. The default value is 2. If the program fails, try increasingly
higher values until it succeeds.
The left and right options indicate that the logo should appear as is on
the left and right side of the tank, respectively, and should be flipped
on the opposite side. This allows logos to be built that have a
preferred direction with respect to the front of the tank.
The logo file is an ASCII file and describes a set of triangluar meshes.
The format is as follows:
# BZLOGO Version 1.1
optional_global_qualifier
command
number_of_points
X-Y 1
X-Y 2
...
X-Y n
command
number_of_points
X-Y 1
X-Y 2
...
X-Y n
...
command
In the above, command can be any of the following:
BGNTMESH [Toc] [Back]
Starts a triangular mesh sequence. This must be the first
command.
SWAPTMESH [Toc] [Back]
Performs a swaptmesh and continues on with new points.
ENDBGNTMESH [Toc] [Back]
Ends one triangular mesh and starts a new one.

side of the tank and reversed when displayed on the right side.

side of the tank and reversed when displayed on the left side.
