(a) Given a random number generator that produces values uniformly in the interval [0, 1], describe how to generate uniform random points in the unit square.
(b) If you generate the point (x, y) with x
(c) Let u = 1 - x, v = 1 - y, and w = 1 - (u + v). Show that applying this transformation to the results of part (b) generates points uniformly at random in barycentric coordinates on the triangle u + v + w = 1, 0 ≤ u, v,w, ≤ 1.
(d) Show that for any triangle PQR, the points uP + vQ + wR are distributed uniformly at random in the triangle, when uvw are generated according to part (c).
