Hello All,
I am new to Papervision 3d and having a strange problem. I am trying to make
a 3d Carousel which will load images from a xml file. I am successfull in
parsing the xml file but the images are not showing. I am using Scene3D
instead of MovieScene3D. I have checked Great White classes and did not find
MobieScene3D class. So I am not sure whether MovieScene3D has been removed
from GreatWhite or not.
Below is my code:

Can anybody guie me where I am making the mistake. Thanks in advance for the
