针对三维泥模表面形貌重建误差低和真实度低的问题,导致逼真效果较差。提出基于Unity3D的三维泥模表面形貌仿真研究方法。分析泥模表面形貌表征,建立三维体素矩阵,计算三维分形维数,并利用泥模表面图像的孔隙个数等条件计算孔隙率,通过对三维泥模表面形貌的数据采集和统一坐标数据,可以完成纹理数据的构建和导入;在此基础上,将Unity3D作为建模工具,介绍了三维泥模表面形貌的建模步骤,根据三维泥模表面形貌的采样点数量划分仿真区域,并构建随动包容盒,分析包容盒中的数据,计算空间变换,可以得到三维泥模表面形貌,结合三维泥模表面形貌表征分析、数据的采集处理,泥模表面形貌三维建模以及泥模表面形貌生成的研究,最终实现了三维泥模表面形貌的仿真研究。测试结果显示,本文方法在对三维泥模表面形貌进行仿真研究时,不仅泥模表面形貌的重建误差小,还具有真实度高的优点,使得三维泥模表面形貌的逼真效果较好,验证了本文方法良好的性能。

For the problem of low reconstruction error and low realism of 3D mud surface topography,the realistic effect is poor.A method for simulating the surface topography of 3D mud mold based on Unity3D is proposed.Analyze the surface morphology of the mud mold,establish a three-dimensional voxel matrix,calculate the three-dimensional fractal dimension,and calculate the porosity by using the number of pores of the surface image of the mud model,and collect data and uniform coordinates of the surface topography of the three-dimensional mud mold.Data can be used to construct and import texture data.On this basis,Unity3D is used as a modeling tool to introduce the modeling steps of 3D mud surface topography.The simulation area is divided according to the number of sampling points of 3D mud surface topography.And construct the follow-up containment box,analyze the data in the containment box,and calculate the spatial transformation,the surface topography of the three-dimensional mud mold can be obtained,combined with the three-dimensional mud mold surface topography analysis,data collection and processing,and the mud mold surface topography three-dimensional.The modeling and the study of the surface topography of the mud mold finally realized the simulation study of the surface topography of the three-dimensional mud mold.The test results show that the simulation method of the surface morphology of the three-dimensional mud mold is not only the reconstruction error of the surface morphology of the mud mold,but also has the advantage of high realism,which makes the surface shape of the threedimensional mud mold more realistic.,verifying the good performance of this method.
