| Abstract: | According to the spatio-temporal relationship between sunlight and the indoor scene,this paper resumed the cognition of sunlight analysis 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. |
