Toggling the stats viewer while manipulating the model via right click and drag may increase the probability of triggering the behavior. This is great news, I've just tried running osgviewer --run-on-demand as suggested and see the problem with the pan causing the view to jump off toward infinity. I can reproduce the bug consistently so there is a good chance I'll be able to home in on the issue.

Re: [osg-users] Camera Manipulator or culling behavior change 3.1.2 vs 3.1.6
Hi Judson. I have refactored the Viewer/CompositeViewer::checkNeedToDo() method so that it now calls a new Viewer/CompositeViewer::checkEvents() method that checks for available events rather than rely upon the more heavier weight eventTraversals() method. The eventTraversals() method design is focused on being done as part of a full frame and was hacked to work in the case of run or demand but didn't handle me moving the frame() event generation into. There are good reasons to move frame() event, but not so good reasons to do a full event traversal as a means for checking whether a full frame is needed or not. The introduction of the checkEvents() method required quite a few changes in other classes to support it, fingers crossed I haven't broken the build in the process of making these changes, unfortunately I can't test out OSX, iOS, Windows builds so will have rely upon the community to test of these changes that I had to make to the platform specific GraphicsWindow implementations. I have now checked in my changes to svn/trunk, could you test them out and let me know if things are working OK now.

Re: [osg-users] How to apply textures to a model in openscenegraph?
If you have a need to actually change the flt file itself to change it to use dds textures, you can write something using the openFLT API. I actually just very recently did this myself. We had several hundred models we were converting to use dds instead of rgb files. The samples given with the API and the documentation should be good enough if you go that route. Look at the egwalk example to figure out how to drill down the structure. To actually change the name you will need to use the mgGetFirstTexture, mgGetTextureSaveName, and mgGetNextTexture.

Thanks for the pointer. I've had a look through the submissions
associated with Android and merge one, but for the Uniform.cpp
submission I've decided to try out a simpler solution - move the
static's from global scope into th Uniform::getNameID() method and
then use the OSG_INIT_SINGLETON_PROXY to force a call to the
getNameID() method. I used this approach as I keeps the code simple
without needing to create another singleton class simply to get around
this platform specific issue.
The code now looks like:
unsigned int Uniform::getNameID(const std::string name)
{
typedef std::mapstd::string, unsigned int UniformNameIDMap;
static OpenThreads::Mutex s_mutex_uniformNameIDMap;
static UniformNameIDMap s_uniformNameIDMap;
OpenThreads::ScopedLockOpenThreads::Mutex lock(s_mutex_uniformNameIDMap);
UniformNameIDMap::iterator it = s_uniformNameIDMap.find(name);
if (it != s_uniformNameIDMap.end())
{
return it-second;
}
unsigned int id = s_uniformNameIDMap.size();
s_uniformNameIDMap.insert(UniformNameIDMap::value_type(name, id));
return id;
}
// Use a proxy to force the initialization of the static variables in
the Unifrom::getNameID() method during static initialization
OSG_INIT_SINGLETON_PROXY(UniformNameIDStaticInitializationProxy,
Uniform::getNameID(std::string()))
This change is now checked into svn/trunk. Could you test it out and
let me know if there is any remaining problems?
Robert.

Re: [osg-users] How to apply textures to a model in openscenegraph?
You don't even need to use the openflight api (is it freelebly available?). Go download the OpenFlight spec from the Presagis website (it is free) and write something that will change the texture name in the openflight texture palette. If you are after using dds instead of rgb you change only the extension in the palette. I have done this several times.

[osg-users] Any recent work on CIGI interfaces to OSG?
Hi, I'm new to OSG, coming in from the direction of FlightGear, but I'm here primarily because I am interested in implementing a CIGI interface to FlightGear, and would like to put as much of this work as possible into an OSG module in order to make it useful to the larger OSG community and not only FlightGear developers. I have read the conversations about doing this from several years ago, but have not found any recent discussion or located any available code drops. I have downloaded the MPV example from CIGI at sourceforge, which is based on OSG, and that is quite helpful, but I wanted to introduce myself here and see if anyone can catch me up on any other existing work in this direction, or give me advice about where to start. Much of the CIGI interface is dedicated to higher order simulation functions (ie celestial bodies, ocean conditions, aircraft controls) which are probably too specific to implement at the OSG layer, but I'd like to make at least a virtual wrapper in OSG which could be inherited by FlightGear and other OSG based projects, each of which could determine on its own which functions to support, and how to support them. Any pointers would be welcome. I am applying for funding for this project in one week, so the more information I can gather before then the better. Thanks for all your efforts!
