we know barycentric coordinates is definedas :(ao +...+an)OP = ao OA++ an OAn,below is two results of the coordinates,please point out OP and OAO OA1 -- OAnBarycentric coordinates ...(1,0,0)(1,0,0)(1/2,1/2,0)(1/2,1/4,1/4) (1/4, 1/2,1/4)(1/2,0,1/2)(1/3,1/3,1/3)(1/4, 1/4, 1/2)(0,0,1)(1/2,1/2,0)(0,1/2,1/2)(1/2,1/4,1/4) (1/4,1/2,1/4)(1/3,1/3,1/3)(0,1,0)(O(0,1,0)(1/2,0,1/2) (1/4, 1/4, 1/2) (0,1/2,1/2)
