I need the point cloud of a 3D object for holography image processing. Is it possible to import a 3D model to meshlab and get the point cloud information text file?

Open a model inside MeshLab and then apply one of the many sampling filters (just type "sampling" in the search box). All these filters basically use different strategies to sample points over the surface (e.g. they create point clouds from meshes). For example:

  • Montecarlo Sampling chooses the points in a totally random uniform way enter image description here
  • Poisson disk sampling chooses the points with the constraint that there are no two points closer than a given radius (providing a much more visually appealing distribution) enter image description here

The two samplings shown in the pictures have the approx. the same number of samples (~10000)

  • it works. sorry, I am bigger in working with this software, how can I save the point cloud information as a text file? – sahar kheibari Jul 24 '20 at 05:53
  • Just export the result using a text file format, for example PLY or XYZ are (or have option for being) very simple ascii format. – ALoopingIcon Jul 24 '20 at 06:27
