- Fix a bug causing roads to be displaced from their
true position (caused by incorrect assumption in ElevationSlicer).
- Add control of the minimum width of roads that are rendered at
each LoD level. Control properties under /sim/rendering/static-lod
- Improve marking tiles for re-rendering.
Ensure the STG absolute path can be propagated to all files triggered
by STG loading, including the delayed files and proxied files. This
allows us to attribute errors to the correct scenery path.
Allow us to pass the current error-context from the main thread
into the osgDB loader thread. This is necessary so we can attribute
AIModel (etc) load problems to the correct source.
Adds a LINE_FEATURES STG Verb of the form
LINE_FEATURES <file.txt> <Material>
Where <file.txt> is a text file consisting of line features to be
rendered with the appropriate <Material> definition.
Each line of <file.txt> has the form
<w> <attr> <a> <b> <c> <d> <lon1> <lat1> <lon2> <lat2> ...
Where
<w> is the line feature width in m
<attr> is an integer for attributes - likely a bitmask*
<a> <b> <c> <d> are floats*
<lonN> <latN> are the lon/lat of point N on the line feature
* denotes values that may be feature-dependent. For example to indicate
street lighting, kerbing etc.
There must be at least two points on the line feature.
Move sg_location member up to the base clase, since it’s potentially
useful in more types.
Allow suppression of the report callback when the exception is thrown
Previous code sometimes gave a SEGV in _callback's destructor when
setCallback() was called; this is on Linux with g++-8.3.0. Have tried various
alternative ways to initialise _callback but the problem persistend.
So have switched to an old-style function-pointer plus void* approach.
simgear/io/HTTPClient.cxx
Support range in HTTPRequest's. Set CURLOPT_MAX_RECV_SPEED_LARGE if request's
getMaxBytesPerSec() is non-zero.
simgear/io/HTTPFileRequest.cxx
simgear/io/HTTPFileRequest.hxx
Added 'bool append' to constructor args; if specified we assume that, if
the output file already exists, it is from an interrupted download, and we
use an http Range header to append any remaining data.
Support a std::function callback when new data is available.
Added setMaxBytesPerSec() to limit download bandwidth; useful for testing.
simgear/io/HTTPRequest.cxx
simgear/io/HTTPRequest.hxx
Added support for setting Range header.
In both simgear/io/HTTPClient.cxx and simgear/io/HTTPRequest.cxx, if
a range is specified, we treat http results 206 'Partial Content' and
416 'Range Not Satisfiable' as success.
Generate random vegetation of VPB tiles. Currently
prototype that generates same vegetation for all landclass types.
Needs additional work to
a) make the scenegraph more efficient
b) support different material definitions of vegetation.
Fix the cull callback to continue with normal culling. Also move
where the particle frame is added to the scene graph, to be sure
we don’t modify the scene during OSG traversals.
Ensure all data members are correctly re-initialzied when doing a reset.
This shoed up as negative ‘bytes downloaded’ counts after a TerraSync
abandon and retry.
