Re: [Plib-users] Problem with rotations

[Ben W. <za...@ec...>]

I did read these articles but I will read them again. But I did use a matrix
stack from the rotations and I am only rotating around 1 axe. If I change
the code to just rotate around x it works, and if I change it to rotate
around just z there is no problem, but just y causes some really weird
results. Did you have a look at the code..

Thanks, Ben
