程序运行结果是球被两个光源照射，一个是蓝色的定向光，另一个红色的是聚光-The result is the ball run by two light exposure, a directional light is blue, and the other is red condenser

此程序主要用于冷凝器参数化设计过程中，操作界面的设计，可以实现输入参数生成三维图的功能要求-This procedure is mainly used for condenser parametric design process, user interface design, input parameters can generate three-dimensional diagram of the functional requirements
