Abstract
Nowadays, multiresolution visualization methods become an indispensable ingredient of real time interactive post processing. We will here present an efficient approach for tetrahedral grids recursively generated by bisection, which is based on a more general method for arbitrary nested grids. It especially applies to regular grids, the hexahedra of which are procedurally subdivided into tetrahedra. Besides different types of error indicators, we especially focus on improving the algorithm's performance and reducing the memory requirements. Furthermore, parallelization combined with an appropriate load balancing on multiprocessor workstations is discussed. 1 Introduction A variety of multiresolution visualization methods has been designed to serve as tools for interactive visualization of large data sets. The local resolution of the generated visual objects, such as isosurfaces, is thereby steered by error indicators which measure the error due to a locally coarser approximation of the...
