2) More problematic. Y and Z axis are swapped between OSG and OpenGL. Thus do I have to do a sort of swap between dimensions (so to say) ? For example, I have a camera with view and projection, in osg conventions, and I use the viewmatrix in the shader. That's why I wonder.
They aren't swapped. OSG is using the same right-handed coordinate system as OpenGL, the only difference being that OSG by default uses Z-up whereas OpenGL uses Y-up by default.
There's no need to swap anything, it's just a matter of camera positioning/world layout. Cheers, /ulrich _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
