Computer Graphics in 3D WaveFront Construction
Lucas Fernandes Silva Freitas, Jorge Stol · 2005
We describe an algorithm for simulating the propagation of a seismic wawefront, modeled by a mesh of triangles, through a general three-dimensional geophysical model, with automatic control of sampling density over the expanding front. We show that wavefront modeling is considerably simpli ed by using the Quad-edge mesh data structure. We also describe a control mechanism to eliminate samples when the front contracts.
