Abstract

An interactive visualization of weighted three-dimensional &agr;-hulls is presented for static and dynamic spheres. The &agr;-hull is analytically computed and represented by a triangulated mesh. The entire surface is computed and displayed in real-time at interactive rates. The weighted three-dimensional &agr;-hulls are equivalent to smooth molecular surfaces of biochemistry. Biochemistry applications of interactive computation and display of &agr;-hulls or smooth molecular surfaces are outlined.
