3D Scanning
One of the newest gadgets of the Department of Architecture and Landscape.
In the presentation that Mike Aling gave about this device, we got to understand the essentials about the process of 3D Scanning and how such, could be used both in the design process and, in exploring representational techniques.
The 3D scanning works with a laser technology that moves on the 3 axis to create a 3 dimensional scan of the surrounding space, capturing everything from colors, textures and light intensity.
There is a great potential in this in this technology and even though it is still on its first steps and therefore expensive and under-explored, it is easily understood how and why this can be very exciting and useful tool in the field of Architecture and Landscape Architecture.

The process start in a small touch screen existing at one of the sides of the machine (as can be seen in the photo below); Here we are presented with a couple of options and checks, which help us assuring that the scanner is horizontally and vertically calibrated, choosing the resolution, Geo-referencing our scan and in saving destinations. Quite intuitive and simple.
As mentioned before the scan register everything in an angle of 360d. with the exception of the space bellow it (the ideal place to put your backpack) and behind objects & walls.
The process take between 4 minutes and 3-4 hours depending on the resolution, and should be repeated accordingly with the space/area and obstacles on the way.
Once the scan is finish, the file needs to be processed using software provided by Faro (the scanner manufacture.)
For the scan to be processed, firstly we need to import the san into the software.
Secondly come the registration of the scans. This is related with the positioning of the individual scans in order to get one unitary scan.
Once all this is together into one 3D representation (as seen bellow),
we are presented various options, from clipping the scan
to the adjusting the triangular density (related with the mesh quality of the surfaces.
As can be seen bellow, the final result is not only a accurate digital representation of a space, but thanks to some glitches, has some abstract representations.
The scan can at the end be exported into various formats and then used in Rhino, 3D StudioMax, etc.
