这节需要把顶点布局写在文件里面,为了方便,因为一大串非常抽象的坐标放在CPP和程序混在一起非常的不方便。
下面全为c++知识,读取文件里面的特定格式的数据:
Vertex Count: 36 Data: -1.0 1.0 -1.0 0.0 0.0 0.0 0.0 -1.0 1.0 1.0 -1.0 1.0 0.0 0.0 0.0 -1.0 -1.0 -1.0 -1.0 0.0 1.0 0.0 0.0 -1.0 -1.0 -1.0 -1.0 0.0 1.0 0.0 0.0 -1.0 1.0 1.0 -1.0 1.0 0.0 0.0 0.0 -1.0 1.0 -1.0 -1.0 1.0 1.0 0.0 0.0 -1.0 1.0 1.0 -1.0 0.0 0.0 1.0 0.0 0.0 1.0 1.0 1.0 1.0 0.0 1.0 0.0 0.0 1.0 -1.0 -1.0 0.0 1.0 1.0 0.0 0.0 1.0 -1.0 -1.0 0.0 1.0 1.0 0.0 0.0 1.0 1.0 1.0 1.0 0.0 1.0 0.0 0.0 1.0 -1.0 1.0 1.0 1.0 1.0 0.0 0.0 1.0 1.0 1.0 0.0 0.0 0.0 0.0 1.0 -1.0 1.0 1.0 1.0 0.0 0.0 0.0 1.0 1.0 -1.0 1.0 0.0 1.0 0.0 0.0 1.0 1.0 -1.0 1.0 0.0 1.0 0.0 0.0 1.0 -1.0 1.0 1.0 1.0 0.0 0.0 0.0 1.0 -1.0 -1.0 1.0 1.0 1.0 0.0 0.0 1.0 -1.0 1.0 1.0 0.0 0.0 -1.0 0.0 0.0 -1.0 1.0 -1.0 1.0 0.0 -1.0 0.0 0.0 -1.0 -1.0 1.0 0.0 1.0 -1.0 0.0 0.0 -1.0 -1.0 1.0 0.0 1.0 -1.0 0.0 0.0 -1.0 1.0 -1.0 1.0 0.0 -1.0 0.0 0.0 -1.0 -1.0 -1.0 1.0 1.0 -1.0 0.0 0.0 -1.0 1.0 1.0 0.0 0.0 0.0 1.0 0.0 1.0 1.0 1.0 1.0 0.0 0.0 1.0 0.0 -1.0 1.0 -1.0 0.0 1.0 0.0 1.0 0.0 -1.0 1.0 -1.0 0.0 1.0 0.0 1.0 0.0 1.0 1.0 1.0 1.0 0.0 0.0 1.0 0.0 1.0 1.0 -1.0 1.0 1.0 0.0 1.0 0.0 -1.0 -1.0 -1.0 0.0 0.0 0.0 -1.0 0.0 1.0 -1.0 -1.0 1.0 0.0 0.0 -1.0 0.0 -1.0 -1.0 1.0 0.0 1.0 0.0 -1.0 0.0 -1.0 -1.0 1.0 0.0 1.0 0.0 -1.0 0.0 1.0 -1.0 -1.0 1.0 0.0 0.0 -1.0 0.0 1.0 -1.0 1.0 1.0 1.0 0.0 -1.0 0.0
