We present a method for parameterizing subdivision surfaces in an as-rigid-as-possible fashion. While much work has concentrated on parameterizing polygon meshes, little if any work has focused on subdivision surfaces despite their popularity. We show that po-lygon parameterization methods produce suboptimal results when applied to subdivision surfaces and describe how these methods may be modified to operate on subdivision sur-faces. We also describe a method for creating extended charts to further reduce the distor-tion of the parameterization. Finally we demonstrate how to take advantage of the multi-resolution structure of subdivision surfaces to accelerate convergence of our optimization
