You forgot to mention the languages that Tolkien made. His history for them
is quite interesting also.

    That's on my list. I hear it is fairly simple to learn if you are a
Latin-based native speaker.

Here is a translation (of sorts) of your comment.

The language uses an accusitive case for the recipent of the action. So in 
one instance " a male dog" could be spelled "hundo" and in another, 
"hundon". Means you have to listen verry carefully to how things are said 
to catch the meaning.

    Well, they gotta fix that ^ business... Other than that, as is true of
french italian and spanish, you can pick out root words and get most of the
meaning.

A strange mixture of Spanish-, Italian-, Romanian- and Latin-like
ingredients. All Roman languages. BTW should "Latinderivite" really be
a single word?

All true, with some German and Greek roots in there too.

It could well be as we wern't all too sure how to construct that one. Some 
words are constructed by concatanation.
i.e. Mang^o "food" + c^ambro "room" = mang^oc^ambro "dinning room"

It might look better if you could see the characters in proper format.
The "^" should be over the character that it comes after. Until all the 
world lives with unicode, that is the best I could do. There is c^, g^, h^, 
s^, and a u with a small symbole over it.

    I went through and set up two letter combinations for every phoneme I
could find and pronounce (for my own constructed language), using standard
American English character pronunciations. It seems like the folk who
developed Esperanto could have done something similar.

It occurred to me that it ought to be possible to detect whether two
convex objects had collided by tracing in both directions along the line
that joins their centres.

Consider two convex objects that are not touching. As we look along the
line that joins their centres we encounter the significant points in the
following order:-
        Centre of object 1
        Surface of object 1
        Surface of object 2
        Centre of object 2

If the objects are moved closer so that they intersect, then the order
changes to
        Centre of object 1
        Surface of object 2
        Surface of object 1
        Centre of object 2

(With concave objects all bets are off. It's possible for two concave
objects to touch at the ends while there is still a gap between them
along the line that joins their centres).


I came up with code that looks like this

// trace object2 from the centre of object 1 and vice verca
#declare Surface2 = trace(Object2, Centre1, (Centre2-Centre1));
#declare Surface1 = trace(Object1, Centre2, (Centre1-Centre2));

// The objects intersect if Surface2 is nearer to Centre1
// than Surface1 is
#if (vlength(Surface2-Centre1) < vlength(Surface1-Centre1))
  #debug "They intersect\n"
#else
  #debug "They don't\n"
#end

But that code can sometimes give the wrong answer if the objects overlap
to such an extent that the centre of one lies inside the surface of the
other. For example, if the centres are very close the order might be
        Surface of Object 1
        Centre of Object 1
        Centre of Object 2
        Surface of Object 2
and the surfaces could be at any distance.



I think that this works

// trace object2 from the centre of object 1 and vice verca
#declare Surface2 = trace(Object2, Centre1, (Centre2-Centre1));
#declare Surface1 = trace(Object1, Centre2, (Centre1-Centre2));

// The objects intersect if the centre-centre distance
// is less than the sum of the centre-surface distances
#if ((vlength(Centre2-Centre1)  < (vlength(Surface1-Centre1) +     
     vlength(Surface2-Centre2)))) 
  #debug "They intersect\n"
#else
  #debug "They don't\n"
#end

I'm wondering, with the centers (Am. sp.) known, if you might not be able to
use max_extents to learn where the outer edge of the object lies...
