Hi all, I have checked in an update to the ground intersection code. This new implementation utilizes a pre built bounding volume tree that is attached to the scene graph userdata.
More detailed models near the aircraft should no longer kill performance like it happened with the old grondcache. Movement of objects, in particular the carrier, is no longer tracked by carrier special data. Instead movement is expressed in a generic way. Currently all ships have the velocities set and should be visible by the ground intersection code of the main model. That is you should now be able to land on any ship - at least with a helicopter. ... well, the lack of my current helicopter flying abilities I have not tested this :) There is still a groundcache implementation that collects a subset of that collision tree around the aircraft and provides a fast shortcut for intersection tests within the near environment of the aircraft. For my test machine, I get frame rate improvements up to 10%. This implementation provides also the groundwork for better intersection tests than just that elevation query that is used for all collisions. These will show up in the near future in the main model interface so that FDM programmers should be able to make use of that. If you encounter any problems please report.
