| Abstract |
We present an algorithm for adaptively extracting and rendering iso-
surfaces of scalar-valued volume datasets represented by quadratic tetrahedra. Hier-
archical tetrahedral meshes created by longest-edge bisection are used to construct
a multiresolution C0-continuous representation using quadratic basis functions. A
new algorithm allows us to contour higher-order volume elements efficiently.
