Oneplus Two 3D model

thingiverse

This is a 3D model of the Oneplus Two. I created it as a reference to design parts for it. The doubly-curved geometry of the rear surface was the trickiest part to model, and it is as close as possible to the shape that I obtained through a 3D scan of the phone. rev. 1: outer dimensions fixed. Small discrepancies still present, as the edges of the phone aren't straight but slightly angled... How I Designed This Step 1: pictures for 3D model I captured approx. 40 images of the back of the phone from different angles. Step 2: 3D reconstruction I loaded the pictures in Autodesk 123d Catch, and have it reconstruct the shape. All the magic is done in the Cloud... Step 3: Load point cloud in CAD software Thanks to the University I am studying at, I have access to CATIA. Very few basic steps (good tutorials can be found in Youtube) Shape => Digitized shape editor => Import, to import OBJ mesh => Activate, to select only the points on the back of the phone Shape => Quick Surface Reconstruction => Power Fit, to fit a surface on the selected points Brown: surface from points cloud; yellow: fitted surface Step 4: model I reconstructed, through splines, the top and bottom edges of the back side (1 and 1'). I added two additional intermediate segments, to better capture the curvature (2 and 2'). The lateral edges were simply straight lines (3 and 3') and, once more, to capture the curvature I added two additional segments along the height (4). A Multi-Sections surface was then created over these lines. I then extruded the body up to this surface, and added details (usb port, loudspeaker holes, side buttons...). By comparing, in MeshLab, the reconstructed mesh and the 3D model, you can see a good match.
