[Papervision3D] Help With Layers and Zoom

[Angelo]

Hi guys,

I'm sending this message because I'm desperate. I'm searching all over 
the internet about 2 weeks now to understand Papervision and I'm almost 
getting next to understand how it works but I'm loosing something. Well, 
here's my problem:

I'm making a vídeo website, that will have 3 categories, each with some 
videos, loaded from a XML. Each category will have a layer with its 
thumbnails. Once an user click the thumbnail, it centers on the screen 
and zoom, if the person clicks again they can watch the video. Well, the 
three categories will have each a layer and they will be one in front of 
the other, each with a different depth and blur. The ideia is to change 
the category with the mouse wheel, but i'll figure it out how i'll make 
this later. My issue is how to make those three layers, put some 
thumbnails inside each one, make the mouse button works and change its 
depths and z-order.

I don't know if I have to make 3 scenes, or 3 planes, or 3 sprites, how 
to put some movieAssetsMaterials inside the Plane, I just don't know 
what is the logic for this specific problem. I'm not waiting for you 
guys to give me the final solution, I just hope some advices like: "you 
will have to make 3 sprites, one camera and ... " and i'll try a little 
more. If you guys know some good tutorial or example that mix some of 
the things I said, i'll reeaaally appreciate.

Thanks in advance!
Angelo
