Artur, I have no interest in debating matrix documentation with you. It
was simply an example that I tossed out quickly. I did check the pdf
doc you mentioned. It doesn't provide any more information in this
specific case.
If all you do is toy with Java 3D and make little demos then I agree,
the documentation is adequate. But when you step to making full scale
applications and need to interact with other references (such as 3DS
format) then suddenly that missing spec here or there can create a lot
of work and confusion.
Your usage of "I suppose" indicates that you are also guessing at the
notational scheme used by Java 3D. Are we seriously supposed to code
based on guesses?
