You can use the SuperPatch min_extent and max_extent functions. if you
want to use official POV only, try this. Use Warp's mesh compressor
(Unkle Ken knows the link) and make a macro to read the points list
and find the min and max extent. If you can't do it, I'll do it for
you, just let me know.

Warp's mesh compressor
http://www.students.tut.fi/~warp/

Also if you are converting from another 3d format to a pov mesh two
conversion utilities will give you those figures.

3DWin has a menu function that display these amounts for each mesh object:

wctv2pov actually supplies the min/max extents in the file it produces:

  I was thinking of your mesh smoothing utility and apologize for my faulty
memory and any inconvenience this may have caused anyone. I am sorry for this
indiscretion of mine and will endeavour to get my facts straight in the future.

Thanks Peter.  I am still having trouble with the macro feature so can
you do it for me?  The reason I need this is because I read about a
great technique for texturing models.  You render an orthographic view
of an object, paint it up in PSP, then use the result as an image map
(flat mapping).

Steven,

I got your mail and made the macro you requested. You mail addy seems
to have some kind of problems. I tried to send through both my ISPs
and though netaddress.com to no avail. Please download the file from
here:

If I recall correctly Howard Day makes his amazing sci-fi images using
this technique. Perhaps he can give you some good advice on it.
