Using Meshlab to Clean and Assemble Laser Scan Data

Step 5 Flattening the Layers

After all the mesh files have been aligned and processed, click on the Layer icon to open the Layer Dialog menu. Double check to make sure that all of the aligned layers are visible. Then go to Filters/Layer and Attribute Management/Flatten visible layers. A pop-up window will open displaying the different options. I tend to leave the default options since I have saved often and it is easy to go back to a previous version. Click Apply. This will flatten all of the layers into one mesh that can then be run through a smoothing filter. At this point, if the scan data included color information, Meshlab will remove it from the new combined mesh.
