We give the two different possibilities for subdivision of Powell-Sabin splines on uniform triangulations. In the first case, dyadic subdivision, a new vertex is introduced on each edge between two old vertices. In the second case, sqrt(3)-subdivision, a new vertex is introduced in the center of each triangle of the triangulation. We give subdivision rules for both cases.
