摘　　要：为了解决计算机图形学中曲面拟合知识点授课过程中重理论、偏抽象、不直观等问题,以课堂中的网格模型分割、3D散乱点云数据球面拟合及3D散乱点云数据椭球面拟合等关键知识点为例,开发了“基于3D散乱点云数据的球面拟合、椭球面拟合综合实验平台V1.0”。利用该平台软件可以较为直观地掌握网格模型数据提取、球面最小二乘拟合和椭球面模型拟合重构等技术原理。该平台不但可以助推课堂教学,而且还在教师科研项目、大学生科创竞赛中发挥了良好的作用。In order to solve the problems of theoretically orienting, too abstract content and non-intuition in the teaching process of surface fitting knowledge in computer graphics, the mesh model segmentation, 3 D scattered point cloud data spherical fitting and 3 D scattered point cloud data ellipsoid fitting are selected as the key knowledge points. A "spherical surface fitting and ellipsoidal surface fitting comprehensive experimental platform based on 3 D scattered point cloud data V1.0" was developed. By using this experimental platform, the students can intuitively understand the technical principles of mesh model data extraction, spherical least squares fitting and ellipsoidal model fitting reconstruction. This platform can not only promote classroom teaching, but also plays a good role in the teachers’ research projects and the college students’ science and technology innovation competitions.
