问题 I have millions of xyz-coordinates from multiple point cloud files which I am storing inside a 2-dimensional numpy array: [[x1, y1, z1], [x2, y2, z2],..., [xn, yn, zn]] . I want to filter all the points which are inside a specific bounding box described by 4 coordinates [[x1, y1], [x2, y2]] i.e. the lower left and upper right coordinates of a rectangle. I have already found the following piece of code to filter coordinates with numpy and it's almost what I want. The only difference is (if I'm

问题 after running the Screened Poisson Reconstruction in Meshlab, I got the mesh with some extended surface as in this figure Does meshlab support any tools for removing that? 回答1: MeshLab is using an implementation of PoissonRecon, which is found here: https://github.com/mkazhdan/PoissonRecon What you are seeing is due to the default boundary condition used by the algorithm, which is a Neumann boundary condition. Unfortunately, MeshLab does not allow you to modify which boundary condition is

How can I rotate the pcl::CropBox wrt its own particular axis rather than global axis? or how can I apply affine transform to pcl::CropBox?
