This paper presents an algorithm for generation of a force field from point cloud in three-dimensional space. The force field is calculated based on the approach of gradient vector flow (GVF). Therefore, the force field is named as 3D GVF field. By converting the point cloud into a 3D edge image, the algorithm diffuses the gradient of 3D edge image along the gradient direction of 3D edge image. The generated 3D GVF field of point cloud can be further used for point cloud processing such as segmentation, reparation or recognition.
