New Trends in Subdivision

1:45 PM-3:45 PM
Room: Rio Grande Ballroom

During the last two decades, subdivision evolved as a simple yet flexible method for modeling geometric shapes. Starting with a coarse polyhedron, a subdivision scheme defines a sequence of increasingly dense polyhedra that converge to a smooth limit shape. Modeling with subdivision is simple since only discrete geometric entities such as points, edges and polygons are involved. Yet, subdivision schemes are flexible since the actual refinement rules can be chosen very generally. Much of the early research on subdivision focused on the construction and analysis of subdivision schemes that produce smooth surfaces. More recent research has shifted the focus to adapting subdivision to the needs of real-world modeling systems. The speakers in this minisymposium will highlight two areas of practical interest. They will discuss methods for dealing with interesting topological features such as boundaries and creases and modeling of several types of physical phenomena using subdivision.
