Subclass Terrain nodes in the scenegraph to express terrain LOD and area covered in lon/lat? use the scenery intersect ( as before ) to get exact contact point.use scenery_available() to wait for the highest level pagedLOD to load - next.get rough estimate to position the aircraft viewPos - DONE!.I can get a more accurate position by querying the DEM, but this isn't accurate enough - I'm still to high off the ground for a good trim, and I bounce off the ground on init - breaking new Cessna's gear. Ugh - the original altitude was a hack I added to get moving. I'll need to move up the camera positioning to start terrain loading before fdm is initialized. It looks like aircraft final positioning ( or a switch to cockpit view ) is starting the actual terrain loading. The entire scenegraph is loaded before FDM initialization, and the database pager is traversing the pagedLOD nodes, but the viewpoint is such that all of the pagedLOD nodes are culled. On first attempt, the groundcache is initialized with the first LOD ( very rough ) giving incorrect altitude. The FDM is also started via subsystem init, but queries the terrain engine until scenery is available given a certain radius around the aircraft. What it does NOT do, is start paging in terrain. ![]() This populates the pagedLOD tree for the whole world. On startup, the terrain is initialized via subsystem init. PagedLOD database is created at subsystem init time in Scenery/terrain_pgt class I am seeing tile border 'valleys' from space. NOTE: There may be an issue generating low LOD in the tool, or loading them in Flightgear.
