读取3D模型（wrl格式），获取控制网格，拾取控制网格上的顶点，改变其空间位置，相应的模型会随着变形。-Read the 3 d model (WRL format), access control grid, pickup control mesh vertices, and change the space position, the corresponding model with the deformation.

读取3D模型文件并显示3D文件，并能从串口获取控制数据控制3D模型的转动-3D model file to read and display the 3D files and control data from the serial access to rotate the 3D model
