- W2383171605 abstract "During the flyover of large-scale terrain,in order to eliminate the popping effect of switching among levels of detail and to increase the frame rates with high image quality,this paper put forward a new bottom-up modeling strategy,which constructed simplified terrain triangle mesh globally and updated mesh nodes dynamically.Employed hybrid culling technique based on blocks and triangle faces and simplified computing method for screen-space errors to select appropriate terrain nodes rapidly.Then updated the Delaunay terrain mesh by adding nodes,deleting nodes and modifying locally.At the same time achieved self-adaptive control for screen-space error tolerance during the terrain flyover.Results of simulation experiments demonstrate that the algorithm eliminate popping effect effectively,and has a higher frame rate compared with other algorithms.So it is particularly suitable for close-distance flyover simulation of large-scale terrain." @default.
