1 Loading an object



Figure 1 - 3D Builder Start Screen​


3D object can be loaded using 3 different methods. One can either pick a model from the 3D Builder Library, load them from an external file or create a new one from a Kinect v2 Sensor scan (see 3D Scanning).

Loading an object from a file can be done by pressing the Load icon. 3D Builder currently supports the following file formats:

· 3MF (load and save)

· STL(load and save)

· PLY(load and save)

· OBJ (load only)

· VRML (load only)

Control


Description


Shortcut




Move mode: dragging one of the arrow will move the object in the selected dimension.



R




Rotation mode: dragging one of the arrow will rotate the object around one of the 3 axis whose origin is at the center of mass of the object.



E




Scale mode: dragging the arrow will scale the object following the direction of the arrow.


Note: rotating the camera can change the side on which the arrow is displayed. This can be very useful to scale an object in a desired direction.


W (keeps the aspect ratio on)



Q (removes the aspect ratio)





Edit the value of a move, a rotation or a scale.

Note: Pressing the unit measure in scale mode will switch it to percentage.

6.2 6.2 Materials


When the File Mode is active (
), the material tool appears (Figure 6) the user can then add materials to the material tool by pressing + and pick his material from the material selection (Figure 7). Then the user can select the object and press a material from the list to apply it.

8 3D Scanning
8.1 General controls


When the scan icon
is pressed, a user can perform 3D scans using a Kinect v2 sensor for Windows. To perform a scan, the user must satisfy the below requirements:

· 64-bit (x64) processor

· Dual-core 3.1-GHz (2 logical cores per physical) or faster processor

· USB 3.0 port dedicated to the Kinect for Windows v2 sensor (Intel and Renesas controllers)

· 4 GB RAM

· Graphics card that supports DirectX 11

· Windows or Windows Embedded 8 or Windows 8 or 8.1

The user can set the Size detected by the sensor (Figure 12) and the resolution of the scan (Figure 13). After each modification of settings or before starting to scan the sensor has to be reset. Once enough data is collected press complete to open the scan in the 3D builder editor.

8.2 Tips for better scans


The quality of a scan is affected by 3 major factors:

· The quality of the GPU: a high-end GPU will allow for higher frame-rate and will produce better scans. Optimal results are obtained with 20fps or more.

· The quality of the lighting: a setting without any visible shadows will produce the best results. The more diffuse the light is the better the colors will be captured.

· The background: the distance between the background and the object to be scanned should be maximized, this avoids having artifacts from the background to be captured by the sensor. Additionally, non-reflective background works better as reflection will create noise around the scan.



Scanning can be performed in two ways, either by moving the Kinect v2 Sensor around the scanned subject. Or by fixing the Kinect v2 Sensor and rotating the scanned subject. The second option has proven to provide the most optimal results when scanning big objects.
