It is shown that the idea of space-angle synthesis may be used to provide a new framework for the derivation of discrete ordinate methods. It is also shown that within this framework one can cleanly and systematically incorporate various strategems aimed at overcoming the ray effects that plague discrete ordinate methods in two- and three-dimensional problems.
