Two comments here.
It might not be too good an idea to go high profile with the use of the word
"LEGO" in the site. James did not name the program "legodraw", and for a good
reason. Starting up a slick websight presence as ldraw.org, and then openly
flaunting it as "LEGO" would not be wise. Corporate toes should not be
stepped on.
I strongly recommend that you avoid the implication of LDraw being officially
Lego.
Now, for the camera views.
First, screw all the other methods of figuring out how to place a camera. Stop
trying to fathom X,Y,Z coordinates with your fingers, and put your left hand
down. :-)
Forget the lattitudes and longitudes, and translations and vectors and all that
other $%#!.
Once you have the .pov file made, go back into LEdit. Place a light.dat about
where you want the camera to be. Then place another one where you want the
camera to look_at or point.
Save the file. Open it in a text editor. The first 3 coordinates of the
first light dat directly correspond to the camera location coordinates in the
pov file. copy and past them from the .dat to the .pov.
Do the same with the second light.dat's coordinates. Paste them into the
cameras Look_At coordinates.
Make sure you paste into the proper places.
Render and thank me later. :-) (1)
Or better yet, thank Lars for using the same coordinate system that makes this
possible. (2)
-- Terry K --
1. If the render is not just right, go back to LEdit and move the light.dat's
around. copy and paste some more.
2. In case it is not obvious, this trick works for POV light coordinates as
well. :-)
