After testing with multithreading there were still problems related to
scope and transmitters - because a transmitter that was on the stack
as an object could go out of scope before a notify all had finished
and lead to invalid data and a crash
The solution is to always have Recipients allocated via new() and to
use a shared pointer to manage the scope and garbage collect when the
last reference goes out of scope.
To achieve the threadsafe minimal locking the rules are as follows;
* All recipients must be allocated via new()
* Register and DeRegister will only happen when on the outermost
level of NotifyAll.
- all other add or delete will be put into the pending queue and
added at the start of the next outer notify all
- at outer level notify all a lock will be taken to process pending
items
* during the main notify processing there will be no locks - however
it is also assumed that the recipient list will not be changed
- Add and AREA_FEATURE_LIST STG verb.
- /sim/rendering/static-lod/area-features-lod-level to control point at
which such feature are rendered
- /sim/rendering/static-lod/lod-leve[n]/area-features-min-width sets
the minimum width for feature rendering at that LoD level.
STG Format:
AREA_FEATURE_LIST <file> <material>
File format:
Area Attrib A B C D lon0 lat0 lon1 lat1 lon2 lat2 lon3 lat4....
where:
Area is the area of the feature in m^2
Attrib is an integer attribute (currently unused)
A, B, C, D are generic float attributes. Their interpretation may vary by feature type
lon[n], lat[n] are pairs of lon/lat defining straight road segments
- Generate vegetation based on underlying landclass material mapping
- Reduce frame pauses by removing terrain init from update visitor
- Fix a couple of small timing windows causing crashes.
- Rip out various pieces of irrelevant code, simplifying VPBTechnique.
Largely dealing with multiple textures per terrain tile, which we
don't need.
- Use a lookup of the landclass of mesh vertices to identify sections of
the mesh that are entirely in water, and split those out into a
separate water mesh, using it's own Effect.
Report errors from readWAV, and improve attribution for the
format error (include the file path). As a result, mark the individual
exceptions as dont-report, since we will report higher up.
Fixes an error case where a manual TerraSync server is specified; we
would attempt to use an empty string as the OSM2City server, with
hilarious consequences.
