One can use this method to clean the scan until perfection and then export as an STL again. Looks so much nicer now without the hole in the head. You should arrive to a state like the one below. With the resulting face selected, press Ctrl + T to triangulate them. Then press F to fill the space inbetween. shift + alt + right-click is going to do the trick. If full loop is not selected, add shift to the combination. In edge selection mode one can select an edge loop by holding alt and right-clicking on an edge. We are going to insert just a few to create a just-enough improvement over the state that we had before. Now we need to insert some edges between vertices in the space. Use shift + right-click to select the faces and X to delete them. To do that, use the middle-mouse button to rotate, shift + middle-button to pan the view. In edit mode we have to select the faces that we do not want to be there anymore. The same can be achieved by selecting the Edit Mode from the drop-down (drop-up?) on the bottom part of the 3D navigation window. To activate Blender mesh editing mode, select the model by right-clicking on it and hit TAB on the keyboard. We are going to use Blender mesh editing tools to fix it. One of them is to keep iterating on the scan and Skanect, another one is to import the model in Blender to clean or enhance it.Īs you can see in the video loop above, there is a problematic area on the top of the head. In the case of STL files an interactive window opens to let you navigate in 3D space.įrom here one can choose many paths. In Mac OS X Finder file browsing application, once a file is selected one can get a preview of it by hitting the spacebar on the keyboard. Here I use the preview option on Mac OS X to examine the 3D model. Your browser does not support the video tag. Hit Export Preview to save your scan to the disk. Since STL does not store color data, we can ignore the rest of the parameters. What we need is an STL file where the Scale is in millimeters. Simplify, reduce the amount of faces to remove weird artefacts.Īmong sharing options in Skanect the most important one is the ability to Export Model.Make the model watertight (close all the open meshes).In the Process phase there are two important things to be done. Once the scanning process is over, Skannect will reconstruct the point-cloud data and make a 3D model out of it. That can be useful if the computer is far from the sensor and you have to step away from the model in order to stop the scan process to hit the Stop button. You can also set the preparation time (or Delay) as well as the time limit yourself. Once 360deg are covered, hit the Stop button. To scan the object, make it turn around its axis or walk around it yourself. Skanect will give you 3 seconds to prepare. In order to start a new one one has to remove the previous scan by clicking the Trash button and then the Record button. In the image above you can see a screenshot of a completed scan. The rest of it one can leave as is, at this point you can hit the Start button and start scanning. In my case I wanted to scan my flatmate Yana and for that I chose the type of the scan to be Body and the bounding box of it 1x1x1m. When you open Skanect, it asks you the settings for creating a new scan. In human terms it means create a 3D file on your computer and when you open it, you can pan around the object in virtual space as if it would be real. With Skanect and a connected Kinect device one can Record, Reconstruct, Process and Share an object. Microsoft Kinect is a depth sensor emiting infrared radiation to detect 3D shape of an object. 3D Scanningįor the 3D-Scanning excercise I chose to use Microsoft Kinect and the Skanect app for Mac OS X. Nevertheless I decided to come back to this assignment once I would get the electronics part for my final project to a state when I can build a housing around it.ģD printing is a useful way of rapid prototyping and in relation to my final project I can use it to iterate on the housing unitl I get it right enough to move it to injection molding phase. This was one of the weeks when it was hard to motivate myself to complete and document as I have done 3D scanning and a lot of 3D printing with FDM printers in the past.
