Dear all, The following code in the header file MatrixD looks very suspicious to me:
inline Vec3d getScale() const { Vec3d x_vec(_mat[0][0],_mat[1][0],_mat[2][0]); Vec3d y_vec(_mat[0][1],_mat[1][1],_mat[2][1]); Vec3d z_vec(_mat[0][2],_mat[1][2],_mat[2][2]); return Vec3d(x_vec.length(), y_vec.length(), z_vec.length()); } Shouldn't the index order be the other way around? I mean it should be inline Vec3d getScale() const { Vec3d x_vec(_mat[0][0],_mat[0][1],_mat[0][2]); Vec3d y_vec(_mat[1][0],_mat[1][1],_mat[1][2]); Vec3d z_vec(_mat[2][0],_mat[2][1],_mat[2][2]); return Vec3d(x_vec.length(), y_vec.length(), z_vec.length()); } The behaviour of my program was strange before I fix this problem. I'm not 100% percent sure, but since it's of fundamental importance, I still decided to report. Best regards, Tianlan Shao
