I agree on that. I really was in doubt whether or not to add the
logo, but after looking at many renderings I found it to increase
realism very much (as do textures in general, compared to "flat"
faces). I also considered writing e.g. "LARS" i.s.o. "LEGO", like
Paul Gyugyi writes "L3G0". Actually, I was inspired by his

Oh no, no, no!
What is this? Is it that difficult to use the latitude/longitude?
Using the above copy-n-paste will bypass L3P's efforts to place
the model in the center of the image with equal amount of space
around it. You risk cutting off part of the model.
I used the globe concept because I assumed it was easy to grasp.
No worry about X Y Z coordinates, just imagine your model inside
a globe. I even made an illustrative image (at least I thought so):

Could you (or others) please try to explain what the difficult part is.
How did I fail to make the description in
http://www.netby.net/Nord/Mandelvej/Hassing/l3p.html#l3globe
intelligible and explanatory?
That said, I admit L3P lacks a way of specifying the look_at
position, which currently is set to the center of the model.
But the camera position may also be set by -cc<x>,<y>,<z> and
light.dat may be recognized by the -l options (see also -ld).

| (...) Lars, I didn't intend for this to be a "fix" of any type. And the latitude/longitude method is a good one to use. If I sit there thinking about it enough, I can do it. And the automatic centering of the model is a fantastic feature that I (...) (25 years ago, 15-Apr-99, to lugnet.cad.dev)
