There's a picture on the Wikipedia page, just look at where the axis'

Thanks Mark, Gonna go read with the faq's. And you hit the nail on the
head. It looked right, but the behavior wasn't quite right
Time to learn some vector math I suppose. Thanks again everyone. I hafta
wonder if it'd be easier if I just made the day job pay for a few math
courses, I work on campu

It looks correct to me.

Ah, that's your problem right there -- your code

The rotation matrix represents these formulas:

By the way... just for the hell of it, I translated some of the
Japanese, using google.

Japanese text translation taken out of the context of the slides may
not mean much to you; however, if you watch the entire slide show, it

Sorry my post wasn't very clear on what I was doing, or how I might be using
the method -- was trying to keep it short and simple. I built the method
based Point.polar() only tried to adapt it for 3D.
I have an object performing a random walk through 3D space and I'm going to
plot it's position at
What is the information that you know about the point? degree for x,y?
degree for x,z? degree for y,z? Is the distance you are referring to the
distance from the origin? I assume it is.

Thing is, I can download and use PV3D (and have been playing with it) and
were I doing something for work, that's what I'd do. With my own personal

making things easy on myself.
As an aside, I have the AS2 version of that bo
Assuming PaperVision3D or Away3D don't do what you need, there is some great

Must have book btw.

Okay, so I'm taking my first little steps into 3d in actionscript (simulated
with x/yscale for now) and needed a version of Point.polar() (thanks Jason)
to play around with in 3 dimensions. I came up with the code below, but my
math skills are weak enough that I'm not sure it's functioning correctl
