Iso-Surface Extraction and Visualization in Modular Visualization Environment

The Marching Cubes and Marching Tetrahedra algorithms are widely used to generate iso-surfaces of a 3D scalar fields. These methods are very popular for their good efficiency and because they produce triangular mesh that represents extracted iso-surface. This triangular mesh can be processed and rendered by standard graphics pipeline using hardware accelerators and OpenGL API. This approach enables to reach maximal speed of rendering. This paper describes iso-surface extraction and rendering modules and interaction between them under the Modular Visualization Environment (MVE)
