Does the camera's 'y' pos effect the paging?

Fairly simple question: Does the camera's y position have any effect on the paging? IE: If the camera is x amount of units above the trees will they be paged?

I was looking through the GeometryPagemanager::update(...) and it appears to only be taking the x&z axis into account but I could be completely wrong about this.

After a few tests it seems to me that the y value of the camera has no bearing on paging. Since that is the case I was wondering if anyone could give me advice on how to implement the paging to include the y as well.

I have been looking at PagedGeometryManager::update(...) and I figure changes should be made in there but I am extremely new to the system so the solution isn't jumping out at me. Any pointers would be much appreciated.

Thanks for your time.

You would have to revise the core PagedGeometry engine to use a 3D grid rather than a 2D one, update the grid shift code to work for 3D, as well as the LOD determination calculation (which currently only works for 2D) - you may also need to adjust the fade transitions for this. Then, change the #define's in ImpostorPage.h so the impostor renderer by default renders from below as well as above if desired (you'll want to double the number of vertical "pitch" impostor renders as well most likely.
