Hi, I have a few questions as to the functionality of the DatabasePager and PagedLODS in general.If I am mistaken could someone please help me out – but my Understanding of the DatabasePager is this
If we have a 4x4 grid of pagedLOD tiles We start out with osg::PagedLOD loading tiles into the _activePagedLODList if it is within the range as specified by setRange(). So In DatabasePager - if you start within range you get: _activePagedLODList.size()=16 _inactivePagedLODList.size()=0 the relevant pagedLOD files then request the loading of their children based on range? In regards to active/inactive PagedLODs >From a Previous Post: “PagedLODs are registered as inactive when their frame count gets out of synch with the overall viewer. Once they become inactive, their children are released. In other words, if each child has an identical bounding sphere, none of them will get freed until the lowest child is culled” What other factors affect moving the pagedLOD's to the _inactive list? If it is Culled? If it is in the _inactivePagedLODList then it is no longer resident in main memory? - (or it is up to the OS - based on the OS policy?)
