vtk – create a curved 3D arrow
We can use vtkParametricTorus to construct a curved 3D arrow. However, during this process, the opening needs to be closed, and the boundary should be preprocessed: merge nearby points, remove duplicate points, and triangulate. RotationArrow.h RotationArrow.cpp Some interfaces of BasicMethod can be found on the websize.

Two methods used to sample points on a model
Here are two methods used to sample points on a model (surface mesh or 3D polydata). Filter connected points Use BFS (Breadth First Search) algorithm to get connected points in polyData. Iterate through all the points in jumps to achieve the purpose of sampling. Sampling points by spatial distance Calculate Read more…
