Photogrammetry
During this workshop we learnt about photogrammetry and motion capture. Photogrammetry is a very new technique to me but it amazes me how easy it is to 3D scan an object using Metashape and Cloudcompare. Simon Withers talked about how this scanning has been used to create structures, the example he gave was Wood chip barn that was made by students (Figure 1). The barn explored a different method of building using wood, each forked branch was 3D scanned in order to determine the arrangement of the structure digitally which was then cut and interlinked with the used of a robotic arm (Mairs, 2016). This building investigates a different approach to a wooden building in a digital era. It was interesting what these students create from the method of photogrammetry and how they brought it a step further.

Given the opportunity to experiment with 3D photogrammetry, Simon Withers walked with use through how to use with the programmes Metashape and CloudCompare. I decided to try it out with a chair in the studio, take photos around the object to complete the image. When I put it into the program, not only did the points of the chair aligned but also some of the surrounding environment did as well (Figure 2). The incompleteness of the image create and interesting dynamic to the pieces and I think that it is more interesting when the object is incomplete then being complete.

Taking the model out of CloudCompare and into Sketchfab, I played around with the point sizes of the model and how dispersed they were (Figure 4 & 5).
