Real-time Visualization of Urban with Gigantic Amount of Detailed Buildings
Feiyu Yang, Sheng Li, Shaorong Wang, Guoping Wang · 计算机辅助绘图设计与制造(英文版) · 2015
Complex urban scenery is generally composed of gigantic amount of detailed buildings, efficient representation and rendering are essential for its visualization. We present an accelerating method for urban visualization. Our approach can optimize the organization of models in accordance with the quadtree based terrain, which makes the parallelization easier. Through minimizing the draw call within one rendering process, our approach can reduce the time cost of each frame and improve the framerate greatly. Hereby, our system can handle large-scale detailed models with high diversity and also can afford the ability to adjust the rendering strategy automatically according to the state of the hardware.
