Hi folks -- I've noticed that, under some circumstances, Matrix::getRotate() returns a non-normalized Quat. For example, given the following code: osg::Matrix m( +0.00057735, +0.00000000, +0.00000000, +0.00000000, +0.00000000, +0.00057735, +0.00000000, +0.00000000, +0.00000000, +0.00000000, +0.00057735, +0.00000000, -0.57735026, +1.42264974, -0.57735026, +1.00000000 ) ; std::cout << m.getRotate() ; I get this output: 0.000000 0.000000 0.000000 0.500433 This seems odd because, given the same source Matrix, Matrix::decompose() returns a normalized rotation Quat (0, 0, 0, 1). Given that both Quats represent a rotation from the same Matrix, I'd expect them to be identical. (Mathematically, they are identical, except the getRotate() return value isn't normalized.) Is this a bug that needs to be fixed? Paul Martz Skew Matrix Software LLC http://www.skew-matrix.com <http://www.skew-matrix.com/> 303 859 9466
