Collision Detection Optimization of 3d Landscape Design by LOD Algorithm
Journal Title: Scholars Journal of Engineering and Technology - Year 2015, Vol 3, Issue 4
Abstract
Focusing on the visual effect deficiency in the application of standard LOD algorithm for 3D landscape design, 3D landscape designing model based on terrain complexity collision and shading rendering is built in this paper. First, 3D landscape design models are devided into two categories, regular terrain and irregular terrain, and different rules are respectively adopted during model building. Then, select the LOD model scheduling index according to auxiliary viewpoint, estimate light occlusion by virtue of chebyshev inequality, finally complete the shading rendering optimization by establishing fuzzy variance shadow maps. Meanwhile simulation experiment was conducted, and the experimental results showed that improved algorithm had better visual effect compared to standard algorithm. Keywords: LOD algorithm; 3d landscape design; collision optimization; terrain complexity; shading rendering
