3d rotation logic problem.

I have got simple cube and I would like to rotate it.

I want to use global axis.

I wrote code and I have problem.

//edit link to similar topic

When I have different rotation value(in each axis) it doesn't work good.

Sometimes it looks like rotation x is ok, someties it looks like it would be local rotation, sometimes it rotate absolutely crappy.

I do not want to download full apache library but probably I will not have choice .

Function in the end of topic doesn't work properly and because of apply matrix is extremally slow.

Maybe something change recently in that topic.

Thanks for any reply
