[osg-users] Stereo anaglyph: which glasses?

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

Re: [osg-users] [3rdparty] OSG and SDL

Hi Matt, I'd recommend using SDL for joystick input and osgViewer for windowing as the later has far more flexible and powerful windowing and threading support. An example of mixing SDL for joystick input and osgViewer for windowing can be found in the applications/present3D application.

[osg-users] convertLatLongHeightToXYZ

Hi, Can you explain me a little the function osg::EllipsoidModel::convertXYZToLatLongHeight? I don't understand why x and y are calculated based on height. If I changed the height of a model and I don't change the latitude and longitude, x and y change. Why? Thank you! Cheers, lucie
