Change the bucket tiling at the poles not to cross the 0deg longitude and not to cross the 180deg longitude line. This lets some special cases disappear for the buckets as well as for the hierarchical level of detail spt loader. Also change the last degree tiles from spanning 360 degrees to 12 degrees. Before we had 8 nested rings which neither helps scenery paging nor culling. With that change the chunks are about the same order of size than any other tile. Also the tile shapes are much more friendly for culling and paging. Also in presence of the current scenery, this polar tiles contain as of today just totally broken geometry which tells me that also the scenery generation process did not like these rings for the tile shapes. The impact on the current scenery is low. With this change the polar regions do no longer load the tiles that are available in the current scenery builds. The last degree tiles are broken in this scenery version anyway. The next degree that is changed will really loose some tiles that were sensible as of today. All these areas are replaced with sea tiles by the old paging structure. So, you will have at least ground below you when you fly there. A hopefully comming soon scenery rebuild will use this new tiling structure and thus will be the first one providing closed polar caps. |
