I am almost done with a scene I'm worknig on and I need to replace the
cylinder and sphere "trees" with something a bit more realistic. Gilles
Trans tree macro is amazing, and there's always LParser, but the biggest
problem I have is that I can't find the outer extremities of these
shapes to scale them and place them properly in my scene.

I remember that there was an include file of some sort that could find
the outer extremities of any object and build a frame around it... it
was also recommended to help place a text object in the file. Does
anyone remember this or have I been hallucinating again?

The Superpatch has two functions, min_extent() and max_extent() that return
the minimum and maximum coordinates of the object, in other words, its
bounding box. I really don't think you can do this with standard POV
functions.

Don't worry, I removed the virus & cancelled the infected post. My last post

If you want, I can release a version of the tree macro that gives you the
upper and lower corners of the containing box. It's very easy actually,
since all the objects positions are known in <x,y,z> coordinates in the
macro. In fact it's so handy that I wish I had thought of that earlier...
Thanks.

  Thanks, please do, Gilles. Sounds like a useful feature.

That would be great... if it wouldn't be too much trouble I know I'd
appreciate it. This is a great macro and the trees look great, I just can't
place them properly.

Thanks, Josh

You got it. It's in povray.binaries.utilities.
The lower/upper corner of the containing box is displayed on screen after the
end of the parsing, and a commented line is added at the end of the generated
file :
// Tree in box{<-20.8239,-3.15052,-15.6178>,<16.2539,48.6219,22.4758>
pigment{Green}}
If it's buggy let me know (I just tested it on extree1.pov).

So far so good, and it looks amazing!
