Visualization Simulation of Branch Fractures Based on Internal Structure Reconstruction

This paper presents a visualization algorithm for wood fracture simulation based on science and internal structure reconstruction. The can simulate reasonable realistic effect. First, the 3D point-cloud data of bark are obtained using laser scanner, cross-section branch is by voxelization surface mesh model. Then, outer contour shrunk inward to reconstruct annual rings fiber bundles, structures models generated. consists hierarchical model composed several ring-like rings, each ring divided into series continuous fan rings. On basis reconstruction results, generated parameter control be mapped irregularly shaped In this research, branches shape analyzed provide reliable different fractures trees. addition, fractured tree widely applied in fields such as animation film special effects, game scene simulation, virtual reality construction, mechanical research broken branches.
