大规模复杂BIM场景的Web展示方案
|
摘要
BIM(Building Information Modeling)是基于三维数字设计解决方案所构建的"可视化"数字建筑模型,而网页处理大规模3D场景有一定的性能缺陷。现在探索提出了BIM与Web大规模场景结合的绘制方案。首先,对大规模BIM数据进行体素化处理,然后通过区域划分将数据划分为多个连通区域,最后使用基于视锥增量式关注域(Frustum Of Interests)对一个连通区域的数据加载进行进一步的性能优化,提出了一整套的加载方案。最终通过实验,证明了方案的有效性。
BIM(Building Information Modeling) is Based on the three-dimensional digital design solution built by the "visual" digital building model, and web processing large-scale 3 D scene has some performance flaws. Now explores the drawing scheme of combining BIM with Web large scale scene. First, the bulk BIM data is voxelized, and the data is divided into multiple connected regions by region division. Finally, the data loading of a connected region Based on the Frustum of Interests is used to further Performance optimization, put forward a set of loading schema. Finally, through the experiment, proved the effectiveness of the method.
