Oh, sorry. I didn't notice that your 4th parameter
(the number of quadrilaterals needed to define the cone) was set to 2, making it
flat. Try something like 16 or 32.
Also, the comments lie about that parameter
defaulting to 16. I forgot to test for a null parameter there.

Thanks florin!
wow, theres alot of stuff in there. There should be an option in the
constructor to set the precision of the transform3d.. to accomodate
matrices of floats, instead of doubles.
That would greatly help the people who have thousands upon thousands of
transform3ds..

Many peoples looks for that feature, without knowing that it's impossible to
get accurate results for any combination of doubles in the matrix. As much
as I know there is no software library that's capable of reliably getting
the euler angles. Besides that, you can put inside transform3d any kind o
There are the following fixed fields:
- double[16] - the actual matrix,
- int - type
- int - dirty bits
- boolean - auto normalization.
Depending on the methods invoked, there might be additionaly created:
- double[9] - the rotation matrix
- double[3] - the scale matrix

I was wondering if anyone could tell me what non-static data (fields) is

I am curious because I would like to get a better idea of what the cost of
allocating large amounts of Transform3Ds is..
So I am quite sure that there is a 4x4 matrix in there somew
Florin,
Do you think we should make this get method a feature request? I have
seen in the past that people actually want this functionality.. even
though they may not understand the underlying issues.
Thoughts?

I can answer why some of the get methods are missing.
I believe it has to do with the "Gimble Lock Problem". (It has been a
while since I dealt with this, so the name may not be correct, and the
explanation might be bad, but the concept still holds).
Basically, a Quaternion is capable of represen
There is no way you can be sure you get the *exact* angles you have entered.
That's because there are more possible rotations that you can use to achieve
the same effect.
As an alternative to the algorithm you're using, I have previously posted
here a more elaborate algorithm (and more time consum
Implemented. It works, but...
For little angles I get:
Setting angles <0.0,0.5698,0.0>
Back-calculated euler angles are alpha=0.0, beta=0.5698,

Back-calculated euler angles are alpha=-
