This paper discussed new problems during sunlight software application, such as complicate 3D modeling and large scale project computing, even fail to finish computing. Taking PKPM sunlight software as example, which give correspoing creative technology solutions to modeling, such as domestic 3D modeling graphic platform, complicate pitched roof and terrain quick modeling and analyse. For large scale project computing, this paper discussed kernal graphics card GPU accerlation, and also gave some computing time comparison result and real large project computing examples.

Key words: Computer Application, Sunlight Analysis Building Modeling, GPU Computation, Multi-point Analyse, Shadow Outline Calcuation
