The traditional network simulator don't have the ability of simulation for the process of large-scale network security incidents outbreak, we designed a grid-based Internet worm behavior simulator which is consisted of foreground applications and background analog subsystems in parallel. It makes the most of the benefit of the grid computing capability, resource and task management. The experimental...
3D digital library is a hotspot in recent years. With the continuing development of 3D graphics technology, 3D model as the fourth-generation media has been one of the digital resources in digital library. This article analyzes the progress of two directions: 3D model indexing and compression. At last, we propose a simple frame of 3D model indexing and compression in digital library.
