3d Polynomials.


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.
