In this paper, we propose a new set of orthogonal basis functions in the arbitrarytriangular domain. At first, we generalize the 1-D Sturm-Liouville equation tothe arbitrary triangular domain on a barycentric coordinate, and derive a set ofcomplete orthogonal basis functions on this domain. Secondly, we analyze thesymmetry and periodicity property of these functions and classify them into fourclasses. At last, we show some of the visualization results of these basis functions.
