The main reason to choose C++ as the language to rewrite POV 4.0 in, 
would be to make using OOP concepts a lot easier to use. The current 
source code has to mess around with function pointers in order to mimic 
objects. You *could* do the same thing in C++, but there would be no 
reason to do so...it just makes things unnecesarily difficult to modify. 
For example, to add a proximity function in the current source, I would 
have to modify the code for every shape...in C++ I would only have to 
modify a small amount of code in the base shape and it would be 
inherited by all of the other shapes.
I think it's safe to say that most of the reason for choosing C++ is to 
allow making the source code fully object-oriented.
