Re: [osg-users] Using KDtree breaks rendering
Hi Torben, The cull and draw traversals don't use the KdTree data structures at all, and since they only hang off the osg::Drawable leaves of the scene graph they will basically be invisible to all operations on the scene graph unless they explictly look for them. So if enable the build of KdTree is causing a problem then it must be that other parts of the scene graph are being modified somehow. I can't answer how because I've never seen this problem before, and knowing the code I can't think of anywhere that would likely cause a problem like this. I'm afraid you'll just need to dig into the code and try to debug what is happening during the traversal that adds the KdTree's. One thing you could do is write out a copy of the scene graph prior to the addition of the KdTree, and then a copy afterwards to see if there is a difference. Robert.

If I zoom in the scene and approach the ground with the camera, the files directly in fron of the camera are invisible. It seems they are culled away, but not with a flat near plan, but on a per tile base. For better understanding please look at the attached screenshot. It happens with all tiles which have modified height values. It does NOT happen with tiles which were loaded by the pseudo loader but were unmodified.

Re: [osg-users] Stereoscopy in OSG
Hi Mukund, I am confused why you'd want to render to two scenes on the same viewport, this is only something you'd do with interleaved or anaglyphic stereo.

Re: [osg-users] OpenThreads::Mutex works differently on windows and linux
Hi Mikhail, All windows mutexes are in fact recursive/reentrant, while pthread mutexes aren't by default recursive. To make OpenThreads::Mutex work exactly the same under windows and all other operating systems you either have to explictly use recursive mutexes on all platforms or come up with a way of deadlock OpenThreads::Mutex when under windows. OpenThreads::ReentrantMutex is a recursive mutex so you could use this, but use it sparingly as in most threaded code you shouldn't be re entering the same code. Robert.

Re: [osg-users] Stereoscopy in OSG
Hi Mukend, Active stereo will require a quad buffer graphics context, you can't implement it by swapping the contents of the windows yourself. The OSG supports quad buffer stereo graphics context, but... your driver might not. I don'tknow anything about your particular set up so can't comment. Robert.

Hi Mukend, If you are creating the graphics contexts yourself then you'll need to specify the use of the quad buffer stereo in the GraphicsTraits, simply set GraphicsContext::Traits::quadBufferStereo bool to true before you pass the Triats to the createGraphicsContext(Traits*) method. For quad buffer stereo you'll also need to set the Camera DrawBuffer to be left and right for the left and right eye cameras respectively. Robert.

You just have to change the values in the quaternion
Code:

And with that, I've managed to make the rotations right!
Code:

mat.set(osg::Matrix::inverse(*jointsTracker.at(SkeletonJoint::TORSO)));

Re: [osg-users] saving camera view state
What about keeping your cameraManipulator using ref_ptr (instead of deleting
and creating another one.
By the way, your code deals with HOME position, not with current manipulator
position.
If you will be still lost, look at lexolight.sf.net sources. It uses two
manipulators and you can swap between them by using Ctrl. So, the scenario is
not the same but the similar to yours - copying manipulator settings from one
to the other.
Hope it helps,

Date: 20. 3. 2011 20:44:38
Hi, i have a case where i need to delete the camera manipulator and i do so
by
viewer-setCameraManipulator(NULL);
This freezes the camera movement and camera is locked for some editing
features. Now when i toggle the edit button i do
viewer-setCameraManipulator(new osgGA::TrackballManipulator);
But this resets the viewing and looses the current view. So I tried to do
the following
Code:
if(isPickMode)
{
viewer-getCameraManipulator()-getHomePosition(vec3_eye, vec3_center,
vec3_up); viewer-setCameraManipulator(NULL);
}
else
{
viewer-setCameraManipulator(new osgGA::TrackballManipulator);
viewer-getCameraManipulator()-setHomePosition(vec3_eye, vec3_center,
vec3_up); }
But this still resets the view position. How can it set it to the exact
camera view position?
p.s= new to osg

Thank you!
