[sldev] Requesting for texture

[Qian Hao ~]

I am currently studying the part on requesting for texture. Does the viewer only request for texture image that are in the viewing angle or does it request for every primitives in the island? Is the occlusion done before request for texture? 
 
I was looking through the lltexturefetch.cpp and I was wondering what is decodePriority? Does the client program use this to sort what texture image to request from the server first?
 
Thank you,
Qian Hao
