For a point cloud for example, if you have 100 points with x, y, z values, you can create a noise array to add to the point array: >> gaussNoise=randn (100,3); >> scatter3 (gaussNoise (:,1),gaussNoise (:,2),gaussNoise (:,3))

How to Turn a Point Cloud to a Mesh Using CloudCompare

WebThis is a technique for reconstructing a surface mesh from an input point cloud. This approach “learns” from a single object, by optimizing the weights of a CNN to deform some initial mesh to shrink-wrap the input point cloud. A deformable mesh wraps around a point cloud and iteratively learns its internal features to reconstruct a 3d ... WebPoint clouds in many formats (XYZ, OFF, PLY, LAS) can be easily loaded into a CGAL::Point_set_3 structure, using the stream operator.
