The post shows a way to move 3D model to the original point in world coordinate system. The file CMakeLists.txt is similar to https://www.weiy.city/2021/12/find-closest-plane-between-points-in-3d-by-covariance-matrix/. The included file point.hpp can be found in https://www.weiy.city/2020/09/project-point-on-line-and-plane-by-special-direction/. #include <iostream> #include <vtkPolyData.h> #include <vtkActor.h> #include Read more…
