- W4313231805 abstract "With the popularization of large-scale scene applications of oblique photography based on network transmission, aiming at the problem of the lagging and popping in LOD when level switches, oblique photography point clouds are used as the basic primitives to construct the scene, and improve the rendering effect and transmission efficiency on the basis. First, since partly transmitted high-precision data cannot be used to draw, a multi-level hybrid rendering algorithm is proposed, so that the attributes of the high-precision data can be expressed effectively in time. Second, for the low transmission efficiency, a fine-grained point clouds transmission and clipping strategy is proposed. Finally, the normal-based preprocessing within the terrain block is performed, and the priority sorting and culling operation are executed to ensure the transmitted data is maximized. By introducing the evaluation index of distribution and hits in simplified oblique photography point clouds, proposed method can effectively reduce the RMSE and improve the texture quality when level switches compared with conventional splatting surfel rendering algorithm. The experimental results show that part of the high-precision data participating in rendering can make level switching smoothly and timely, which obtained fine visual effects." @default.
