[osg-users] DatabasePager frezzing fps

[Leandro Linardos]

Hi,

I'm using DatabasePager to load a terrain in a quad-tree structure. So, I have a PagedLOD with a TerrainTile for a distance range and some data to load other four tiles for a nearest distance range.

When swithching the PagedLod leve, I'm building the four tiles inside a ReadFileCallback attached to the PagedLod. The elevation data attached to the tiles are 1024x1024 heightfields. This is obviously done in another thread.

The problem is I'm totally losing frames after the ReadFileCallback call. I'm going from 60fps to 0 (during a seconds) and then again to 60 fps. I think that's the issue is in the scene graph update (when the new tiles are added to the scene).

Some ideas? Some config in threads or databasepager i'm not seeing?

Thank you!

Cheers,
Leandro
