A new angular quadrature scheme named Spherical surface Symmetrical equal Dividing (abbreviated to is presented. The evaluations of double moments by and other traditional quadrature sets show that the new is able to provide good accuracy and compete well with others (as for example the and method). Radiative predictions in a black-walled rectangular enclosure containing absorbing-emitting medium indicate that, compared with and the can give higher accuracy than under some order numbers . Numerical experiments demonstrate the computational economy of for some cases.
