sound manager. The interface was simplified and cleaned up a bit, and I
haven't back ported these changes to the plib sound wrappers ... we could
I suppose if someone really had a problem, but I haven't seen anything so
far that would indicate the extra effort is worth it.
gcc 3.4 has changed the rules for unqualified template name lookup. This
affects SGQueue.hxx. The changes I've made are backwards compatible with
earlier gcc versions. Everything else compiles pretty much okay except for a
few warnings. The resultant executable seems a bit faster too.
This is a new patch that allow to define a different
texture for top and bottom of clouds. It uses the
overcast_top.rgb you made for me last time.
What the patch do is to install a ssgStateSelector
instead of a ssgSimpleState for each layer.
The SGCloudLayer::draw method is modified to accept
a boolean that will select the proper state: 0/false
for bottom, 1/true for top.
Then, in SGSky::drawUpperClouds and SGSky::drawLowerClouds,
SGCloudLayer::draw is called with false and true because
we see the bottom of upper clouds and the top of
lower clouds.
Only overcast has 2 textures, the other types share the
same state for top and bottom, but that could be modified
in SGCloudLayer::rebuild.
put all leaf is a seperated branch so that it is
possible to use a pretrav callback to cull out
terrain without culling out light or dynamic
objects. It appears that plib is not calling the
pretrav callback for leaves.
add an optional parameter that would be called to
build the aircraft panel, so that flightgear's
model_panel no longer duplicate code.
add a pretrav callback to models so that we can
filter out models when calling ssgCullAndDraw on
the global scene.
sgSetModelFilter( true ) means that we want to draw
the models. Use false to cull them out.
popped off the stack in a situation where it could be garbage
collected. I believe this is the source of the spurious "non-object
have no members" bug that has been reported.
The message 'Alert: catching up on tile delete queue'
comes from the fact that 48 tiles are scheduled and
added to the cache at startup before the plane location
is initialized. My proposed patch is to initialize
SGLocation with an invalid position and detect this
fact before scheduling tiles. I prefer to do that
rather than testing for lon and lat being 0,0 because
it is a valid position and someone could want to fly
near Accra.
This patch is for windows only. It hides the console window
until there is a message to print. It only support SG_LOG,
that I think is the right way to display something in FG.
