地理学视角下室内三维场景日照分析关键问题

The key problem of sunlight analysis in indoor 3D scene from the perspective of geography

针对太阳光线与室内场景的时空关系,剖析日照分析所涉及的分析框架、场景模型、分析算法,提出并构建基于地理学视角的日照分析框架、概念模型与算法体系,侧重于室内三维场景中太阳光影、光柱的时空过程及其照射效果的模拟,使得日照分析能够真正符合公众需求,从而促进面向公众服务的建筑物建模、模拟理论与技术的发展。

According to the spatio-temporal paper resumed the cognition of sunlight analysis relationship between sunlight and the indoor scene, this from the perspective of geography and the key issues of analysis framework, scene data model and analysis algorithm framework for sunlight analysis was discussed. The analysis framework, data model and the algorithm framework promoted by this paper, is helpful to the simulation of the spatio-temporal process of light cross and light spot as well as the luminous effect caused by sunlight, which will make the results of sunlight analysis practically be used by ordinary people, and promote the development of the theory and technology of the simulation and modeling of the building for public.
