WebOct 31, 2024 · I want to find the closest neighbor to a given point. I managed to do it using numpy. dists = dists.numpy () ind = np.unravel_index (np.argsort (dists, axis=None), dists.shape) idx1 = ind [0] idx2 = ind [1] Thus, the closest point to x [idx1 [0]] is the point at x [idx2 [0]]. How can I do this in pytorch directly? Thank you.

WebDec 1, 2014 · Conversion from a mesh to a point cloud is not similar to jamming the mesh's vertices into a point cloud! Mesh is a sparse representation of a point cloud. Therefore, to convert a mesh to a point cloud, you need to sample points on the surface of the mesh. PCL has a utility for doing that called pcl_mesh_sampling. The source code is located here. WebNov 4, 2024 · 1. @ImportanceOfBeingErnest As noted in the answer, this code, just as the OP's code,does not produce the set of points which are farthest apart, just a set of points fairly far apart (but it saves a lot of time by doing this). It does this by choosing a random first point and then choosing the point farthest away from the current point. Web1. Generate images of the scene and masks¶.
