// ================================================
// convertOSGMatrixToMPVMatrix
// vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv
MPVCMNOSG_SPEC mpv::Mtx4 convertOSGMatrixToMPVMatrix( const osg::Matrix &osgMtx )
{

// OSG matrices are stored "sideways", like OpenGL.
// MPV matrices are stored like you learned in math class (except the subscript is
// backwards; math class convention for refering to an element is Mcol,row).
// They need to be transposed to convert between the two.
result.pcset( osgMtx.ptr() );
return result;
