![]() ![]() Turn on layers from the top menu bar View -> Open Layer Dialog. Change the camera to -1000 so that the sampling program knows that the cloud point data was taken from a large distance, this would give it a better idea where the normals should go. Recompute normals using Filter > Point Set -> Compute normals for point sets, change number to 16 for the number of neighbors and also check the box for Flip Normals. This will create normals pointing backwards, so they will need to be recomputed so that the normals are facing forward. Distribute normals using Render -> Show Vertex Normals. However, further 3D modeling is required to create a base, ground layer, or support platform for the object before a printable code can be generated by the Replicator-G software used by the MakerBot. stl file for 3D printing with the MakerBot. obj Note: Meshlab can export the mesh as a. obj file format to be opened in Maya or Blender. Set the Octree Depth to 9 or 10 Surface Reconstruction Poisson 10a. ![]() From there you can add surfaces to the Model. This will create a new layer called Poisson Mesh. Then, go to Filters -> Points -> Surface Reconstruction Poisson. Click Apply and manually Close that menu. More than 15 for Number of Neighbors Compute Normals for Point Set 8a. In the new window, put a number greater than 15 for the Number of Neighbors. Next, go to Filters –> Normals, Curvatures and Orientation -> Compute normals for point sets. Show Layer Window and select Poisson-disk Samples layer 7a. Open the layers window under View -> Open Layer Dialog and make sure the Poison-disk Samples layer is highlighted. Once the sampling has completed, a new layer will be added. Add two zeros to the Number of Samples and check Base Mesh Subsampling Poisson-disk Sampling 6a. In the Number of Samples, pick between 60000 sample points(sometimes the system crashes.) Remember to check the Base Mesh Subsampling box or you will get an error. Under the Filters tab in the navigation menu choose Sampling -> Poisson-disk Sampling. Saving it at this point provides a good backup point, and the image is zoomed and centered when re-opened from the new file. Or, select the points to be kept points, invert the selection, and delete the unwanted points Delete selected vertices 4. Press ctrl + delete to delete unwanted points from the mesh. If a selection is made around the points you want to keep, then invert the selection using Filter -> Render -> Invert Selection. Rotate the mesh to select points for deletion 3. Rotate the mesh to make selecting easier. Select either the desired points or the unwanted points using the Select Vertices tool. Open the file that was taken from the Kinect in MeshLab. Cleaning up a point cloud mesh of an object in Meshlab so that it can be printed using a 3D printer.ĭeleting Unwanted Background Points 1. ![]()
