[osg-users] Tiny normals: osgviewer vs osgcompositeviewer

[Julien Valentin]

Hi,
Normal scaling happen in osgUtil/TransformAttributeFunctor.cpp l.44 

Code:
        for (osg::Vec3d* itr=begin;itr<end;++itr)
        {
            // note post mult by inverse for normals.
            (*itr) = osg::Matrix::transform3x3(_im,(*itr));
            (*itr).normalize();
        }


All seams right ..
perhaps forcing orthogonality of the 3x3 with pseudo inverse and remove normalization can give better result...Don't know
Cheers
