"Vector calculus"--what grade are you in?
(Yeah! Finished all my homework for the week during class in math! Wish I
hadn't had two friggin' years of repeat in middle school...)

I have not tried this, but shouldn't
camera {
right -4/3*x
sky z
location <soandso>
look_at <anotherpoint>
}
work? Read the section "Placing the camera" in the POV-Ray reference
to learn more about these values.

>"Vector calculus"--what grade are you in?
It's the name of the book, by Mardsden and Troma. Second half of first year
in Univeristy of Oslo, Norway. We're learning analysis if functions with
several variables. You know, this is _the_ class for POV-ray users! After
three weeks, I know enough maths to write my own isosurface code! (I don't
mean to _use_ the isosurfaces, but to code the program itself... That is, If
I was any good at C++ ;)

But POV isn't written in C++, it is written in C. :-)
Although there are plans to rewrite it in C++ for version 4...

I think I have that book! But isn't it Tromba?

These are my opinions. I do NOT speak for the POV-Team.

Thanks, will all of the experimenting I've done with the camera I couldnt' get it
to work. Your code is just what I need.
Thanks

Oops! Of course. (go to www.troma.com for something _completely_ different.)
Must have missed the 'b' there... :/
But the book is great! Why don't you go to
http://www.uio.no/~simenkv/ma105/index.htm and see for yourself? Compare
with figure 2.7.2 in the book and _behold_. I think it's quite similar, only
better... ;)
Simen.

As I said, I have the book, so I just opened it to page 179 and
compared. :) Yours is much nicer-looking, I agree. Also, I see
that it's Marsden and Tromba, so you must have just flipped the
B over and stuck it in the other name. :)
