What about something like this:
@type FunnySphere = sphere{
pos <1.56, 2.34, 1.67> = @FirstTrans
rad 3.245
scale <2.03, 0.02, 4.58>
trans <1.00, 0.0, 2.00>
trans <0.0 , 4.5, 0.0 > = @SecTrans;
tex {........
trans (FirstTrans + SecTrans)
}
}
I'm using the @ as shorthand for #local or #declare.
The difference lies in
@SecTrans= <0.0 , 4.5, 0.0 >;
meaning: declare it for later use, so don't use it at this moment and
<0.0 , 4.5, 0.0 > = @SecTrans;
meaning: use it now, but declare it for later use as well.
I think that the scope of FirstTrans and SecTrans should be inside this
type-declaration only.
Because it may be possible with POV4 to create a new kind of object, the
word "type" indicates the creation of some kind of new object. Maybe we
don't need "@type", but I like it for its clarity.
