Unfortunately, the ones that I have demonstrated aren't perfect either. There's no kerning. One can either have kerning (btex ... etex) *or* play with letters. Have to think about that.

Yes, but why is 10--20 not spread that much, and why is 80--100, but not 60--80 and not 100--120. Must have to do with the blue line, but what? This was modelled after "Jim's" cockpit photo (ttp://www.airliners.net/open.file/438320/L/) -- all other bo105 cockpit photos have an evenly spaced ASI. These just weren't sharp enough.

This @() function proved to be very powerfull and it made creating scales very easy. I can see this function modified to create non-linear scales (exponential, logaritmic ...), scales that go counter-clockwise ... I renamed it to aout() and ainn() when I needed two of it, because MetaPost apparently did not like names like @out() and @inn(). I would recomend to anyone trying to decide how to create instrument faces to at least take a look at MetaPost. With a bit of experience it becomes quicker and a lot more accurate than hand-drawing.

OK, here's a new version, just so you can see how easy instrument face creation with MetaPost is. Note that there's a function @() defined, that maps the real instrument angles to MetaPost angles. So I could directly input all the values as I saw them on the cockpit photo. Also, the program outputs the correct fgfs angles for the *.xml interpolation table.

Well, as of last week, there *is* a working turbine RPM output. The problem is that there's no turbine model in the helicopter stuff. The engine is essentially hardcoded into the Rotor class, it can't be shared with the rest of the code. What needs to happen is that the rotor code should simply export a torque, and let the external code (either PropEngine, or something like it) do the RPM integration.

Just take one of the two presented *.mp files, add a new instrument ("beginfig"
or, in my case, "begininstrument") and add some drawing commands. They are pretty
self-explaining. Then run the file through MetaPost:
$ mpost foo.mp # may be called metapost
$ for i in foo.*; do convert $i $i.png; done
Writing templates wouldn't make sense. It would be like writing a template for
poems. The language isn't hard to understand (at least the parts that we used).
The documentation that comes with MetaPost is sufficient -- look in
/usr/share/texmf/doc/metapost/base/ or wherever your TeX dir is). Ask if you
have problems. Here's a short tutorial:
z0=(2,3); % define coordinate, can also be written as x0=2; y0=3;
drawdot z0;% draw a dot, obviously at z0 (draw works, too)
draw z0--z1; % draw a straight line between from z0 to z1
draw z0..z1..z2; % draw a smooth line through the points
z0=z1 rotated 30; % does what it says it does ;-)

I have a Makefile that creates the rgb and drops it into the bo's instrument dir. No intermediate, manual steps. I would have used gimp, though, if "convert" hadn't produced a decent texture already. What I would change in your *.mp file, is: (1) The position and size of the image: the center of the face should IMHO be at "origin" (0,0). That's a lot more natural, makes rotations easier, and the code easier to read. The canvas should take the later size into account: my faces are already 2^n * 2^m in size. No later cropping required, only "convert foo.1 foo.png". (2) I prefer to use relative units. I don't define u in terms of length units (1 cm), but such that (0u,0u) is the center, (100u,100u) the upper right corner, and (-100u,-100u) the lower left corner. (2) I'd rather use "(0,10u) rotated i" instead of "(3u+10u*cosd(i),3u+10u*sind(i)" (provided that you considered (1). Or even "left scaled 10u rotated i". (3) The position of 10, 12 and 14.
