I need to generate polynomials that are orthogonal in 3d space, with respect to integration over a volume (non-cartesian boundaries). Given such polynomials, how do I generate a C function to compute the lowest order polynomials. (1). How do I determinate appropriate abscissas and weight in order to approximately compute a representation of a 3d function in terms of my polynomials.(2) I also need to compute the line integrals of my function along arbitary lines. Can anyone suggest a good way of doing this in terms of the results from (2). (3). My region is the unit sphere. -- ------------------------------------------------------------------------- Tommy Nordgren "Home is not where you are born, Royal Institute of Technology but where your heart finds peace."
