[osg-users] update node in view using cullcallback

[Cong Ye]

Hi,

I am recently working on a big scene simulation project. To optimize the performance, we consider to only update elements (material color, position, rotation etc.) in frustum or not culled. The most straightforward method come to me is using cullcallback to do the update. I implemented it and it works. However, after come across some online articles, most of them are not suggested to use cullcallback. Could I ask is there any drawbacks to do so? 

Thank you!

Cheers,
Cong
