Other AbstractIn correspondence with the requirement of dynamical process simulation of mountain disasters and the
drawbacks of rendering the whole process of mountain disasters dynamic simulation in real time,the improved LOD
algorithm based on the triangle bintree data structure,is proposed,to realize 3D modelling and visualization of
mountainous terrain. It performs pretreatment of blocking and layering for mountainous terrain data,and uses triangle
bintree to represent terrain meshes. It also dynamically split or merge data blocks with quadtree structures according
to viewpoints as well as the roughness in local terrain,which limit the terrain data in the memory. The experimental
result shows that the method presented in this paper is feasible and efficient,has a low memory expenses,
it can be used to realize real time rendering of very large-scale terrain,which lays a good foundation for whole
dynamical process simulation of mountain disasters.
