[osg-users] Stereo anaglyph: which glasses?

Re: [osg-users] IPhone retina displays
Hi Tom, Am 29.09.10 02:43, schrieb Thomas Hogarth: Good news on this All seems to be working, I've also improved the IPhoneWindowingSystemInterface to handle true resolutions and multiple screens. So on IPad we should now be able to set a window to an external screen and also change the res of the screen (I don't have an IPad though so needs testing, but should work, gulp :) ) In the end I've gone for the approach of IPhoneWindowingSystemInterface providing the actual pixel res of the screen. Then by default if the user does not set a viewContentScaleFactor in their windowData, the screens scaleFactor is used. This means the default context created by osg viewer will always be full pixel res and the window will be full points res. This was so that I didn't have to create a context of a different size to that requested by default. If the user needs backward compatibility they have to set the traits width and height themselves and set the windowData viewContentScaleFactor to 1.0. I still need to do a bit of testing as I think my objective c code is leaking but I'll get the changes checked in asap. Wow, nice work, I am eager to test your new code on the ipad with an external display.

Is there a correct cull setting that I should be using to get everything to display? I tried using the COMPUTE_NEAR_FAR_USING_PRIMITIVES and COMPUTE_NEAR_FAR_USING_BOUNDING_VALUES with this call, but I'm not quite sure what bounding value I should be using or if I should be looking at another culling method. OK, this is good, you've isolated the issue to one of management of the near/far planes, so now it's a case of finding the appropriate technique for you type of application/models. First up the near/far planes are computed during the cull traversal, using COMPUTE_NEAR_FAR_USING_PRIMITIVES will be more accurate and provide a tighter bound than COMPUTE_NEAR_FAR_USING_BOUNDING_VOLUMES but it's more expensive to compute. Both techniques still use clamping of the near/far values to avoid the ratio getting too low which will cause z fighting, this clamping by default pushes out the near value to obtain a specified near/far ratio. The CullSetting::setNearFarRatio(double) sets this value, and Camera subclasses from CullSettings so you can do: camera-setNearFarRatio(0.0001); // default value is 0.0005; It may well be that this in OSG-2.x this near/far ratio is set more conservatively than OSG-0.9.9 and is the reason why you are seeing differences. Have a look at the source code to see what the old default value was. -- For scenes which have a very large depth range that tweaking the near/far planes isn't sufficient it can be useful to using depth partioning, where you render the scene two or more times, varying the region that is rendered in each pass. This osgdepthpartion examples shows this in action. This example is a bit out of date and should really be implemented with viewer slave Cameras rather than in scene graph Camera, but the principles are the same.

Re: [osg-users] Problem compiling 2.9.9 with Qt in MacOSX
Hi Alejandro, You are hitting an issue with OSX support for building against 32bit/64bit in the same binary, in your case you are building the OSG to build both, but then trying to compile against a Qt lib which is 32bit only. Go into CMake and remove the x86_64 entry in the CMAKE_OSX_ARCHITECTURES and then press 'c' to configure and 'g' to generate the build system. Then rebuild the OSG. Or just build Qt against 32 and 64bit. Robert.

Re: [osg-users] convertLatLongHeightToXYZ
Lucie, This is how you would place your model... osg::Matrixd position; ellipsoid-computeLocalToWorldTransformFromLatLongHeight(osg::DegreesToRadia ns(lat), osg::DegreesToRadians(lon), altitude, position); transform-setMatrix(position); where transform is an osg::MatrixTransform node that has your model as a child node. The X,Y,Z geocentric Cartesian coordinates from the lat,lon,alt can be extracted by: osg::Vec3d pos = position.getTrans(); Keep in mind that an altitude of zero will yield a point on the surface of the spheroid for a given lat,lon pair. Any altitude zero is the height above the ellipsoid/spheroid.

Hello Sajjad, Just ran the debugger. and crashes in the following line * viewer.frame(); Are you running a debug build in the debugger? Do you have the debugging symbols for OSG? That specific line is not the site of the crash, it's something that function is doing, so to get to the real source of the crash you need to have debugging symbols and walk down the stack.

Re: [osg-users] OSG , Qt and osgsimplifier
The only suggestion I can think of is to make sure you are using the single threaded threading model: setThreadingModel(osgViewer::Viewer::SingleThreaded); AFAIK, QT viewers will not work with any of OSG's multi-threaded models.

[osg-users] VBO Memory Usage
Hi Robert, I've noticed some issues with memory usage when using VBOs. The attached example generates between 50K and 200K points per frame and creates a new geometry for them with VBO's enabled. If you run the example, it appears as if the VBOs aren't properly being deleted and my graphics memory quickly gets maxed out and it crashes in about 30 seconds. I stuck some debugging output in GLBufferObject::deleteGLObject() and it is never called so it appears as if the VBOs aren't being deleted at all. However, if you run the example with the --fixed argument, the Vec3Array for the points is preallocated to a large number (300K) and the points are just assigned to the array (vs using push_back). This means that each frame is getting a Vec3Array which is the same exact size, but with a varying number of points to actually draw with the DrawArrays. I'm assuming this is causing OSG to take advantage of some kind of VBO reuse as this causes the memory to be totally stable. I'm running the latest SVN version of OSG. Thanks!
