Re: [Opensg-users] using more than one texture at a time...

[Enrico B. <de...@se...>]

thanks Gerrit,
your help was really useful!
Finally i've got the multitexture running, but now i have another
trivial problem...
How do i retrieve the camera position? I am using a SimpleSceneManager
and i saw that the position of the camera is private. With no facility
to query that state... 
How can i bypass the problem? 
Thank you
