A new way to define mesh importance for decimation uses transfer functions and visualizes large simulation data in cases where normal visualization methods are insufficient due to memory limit. Next, a parallel isosurface simplification framework uses pyramid peeling to extract the decimated meshes progressively without generating the original surface.
