Ack.
Defines are horrible. Bad bad things. Java has no defines nor macros. No
goto either. No operator overloading...

Hmmmm...
But it would not be very hard at all to come up with an XML format for
the POV-ray scene and read and parse it in Java. Then feed it to
POV-Ray...

Wide Grin.

I must agree with Jon. There wouldn't be much reason for a JAVA-POV to look
exactly like the old POV, would there? Why would someone want to use it
then, better to stick to the original...
No, the idea was to use a more powerful "real" programming language to
create even more complex "scripted" scenes than "possible" with pure
POV-Script (which means: "Possible in an easier and halfway readable,
maintainable and understandable way", because everything is just plain
*possible* in POV-Script of course, the question is, how difficult it is).
Other people had the same idea earlier, using C++ or Perl for that, I
thought Java would be good for that too...

Greetings,
Johannes.

XML! XML! XML! XML! XML!

Eversince I started reading about XML I thought that a nice 3d description 
language could be made with it. 
Isn't there a team converting VRML into X-VRML?

Because I see no sense in typing 'add new whatever' when you can
substitute it with whatever java has as pre-compiler macro or define.
I understand that it would be great to be able to extract or change
the object properties (like camera.lookAt) but I don't think it would
be a good idea to altogether lose the old syntax. OTOH, if what I am
saying is not possible in java, that's ok.

How about making the necessary extensions to the POV Language and
writing a Java or Perl parser to convert that syntax to standard POV
syntax? This will have the advantage of keeping old syntax while
easily adding new.

I understand. But as Jon already said, Java hasn't any macros or
preprocessor.
