In the area of reverse engineering, much research is being done on capturing the form of an object for inspection and design recovery purposes. When using contemporary reverse engineering techniques to reconstruct an object, many three dimensional data points are collected along the object's surface. Surfaces are constructed from the point cloud data using best-fit polynomial methods. Because of errors (due to scanning and manufacturing techniques, wear, etc.), the point cloud data does not correspond to an ideal replica; therefore, design modifications may be necessary. In addition, the model is incomplete using existing methods unless computer tomography (CT) scans are utilized, which is cost prohibitive, as data collection systems do not readily capture information on recessed or internal features.

在反向工程领域，正在为捕获对象的形式进行检查和设计恢复目的。当使用当代反向工程技术重建对象时，沿对象的表面收集了许多三维数据点。表面是使用最佳拟合多项式方法从点云数据构建的。由于错误（由于扫描和制造技术，磨损等），点云数据与理想的复制品无关。因此，可能需要进行设计修改。此外，除非利用计算机断层扫描（CT）扫描，否则该模型是不完整的，这是成本较高的，因为数据收集系统不容易捕获有关嵌入式或内部功能的信息。
