Real time simulation of the shattering of bridge caused by the blast wave

This paper present a method of simulating the shattering of bridge caused by blast wave.In this method,we use 3DMAX to build the surface model of the bridge and save it in VRML(Virtual Reality Modeling Language),then we use Delaunay triangulation algorithm for the division of the surface model,we introduce a three dimension solid model constituted by prisms to simulate the rupture of the bridge, the generation and movement of the fragments,we adopt a simple blast wave-spherical wave, the initial velocity of debris is calculated based on the control function.After calculating the location of every debris, we can get the simulation of the shattering of a bridge. the effects can be simulated realistically, and this method can meet the requirement of real-time.
