Real-time creased approximate subdivision surfaces

We present an extension of recently developed Loop and Schaefer’s approximation of Catmull-Clark surfaces (ACC) for surfaces with creases and corners which are essential for most applications. We discuss the integration of ACC into Valve’s Source game engine and analyze performance of our implementation.
