Currently this fires on button release, but also after any mouse-wheel movement (since they are sent as buttons). This feels slightly wrong, but can't decide how a spring-loaded know would work, when interacting via the mouse-wheel. Comments welcome.
As part of this, pass the osgGA GUIEventAdapter down into the pick callbacks, which seems reasonable to me. If anyone can foresee issues with this, please let me know and I can adjust the API.
- Add nasal::String for wrapping Nasal string data and accessing
string methods (which eg. could be exposed to Nasal)
- Allow adding functions from C/C++ which are callable on
Nasal strings.
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.
This removes support for exposing and managing classes by just
raw pointers as this made lifetime management of instances
from C++ to Nasal and especially the other way round nearly
impossible. Always using smart pointers saves us from a lot
of headaches.
Since there's no active request during a name lookup failure, explicitly fail all sent and queued requests, so the Request subclasses can take regular failure action.
Work-around a crash on certain Mac builds (I can't tell why other work fine) where the called parameters to apr_pool_create_ex are problematic. Explicitly pass the default values for the function.
As doesnt seem to work to just resize the texture, if changing
the size of the Canvas render target a new FBO is created and
placed on all active placements.
ENABLE_SOUND=0 now works when configuring SimGear, and libSimGearScene can be linked without OpenAL. However, more testing of FlightGear in this mode is needed before it's officially supported!
