Also part of Matt's MArch studies this series of works uses scanning in two ways: to synchronise digital and physical workflows, so objects could be manipulated both by hand and by computer and then to test the success of the final 'stealth objects.' These stealth objects are the tools of a hypothetical insurgency, aiming to go undetected by escalating 3D scanning surveillance techniques. (See Subverting the LiDAR Landscape)
Initial 3D sketch pieces were intuitively carved from Obeche then scanned using a self built 3D scanner and open source scanning software. The digital artefact captures the original form including precise notes, comments and instructions from the surface of the originals. These sketches guide the creation of CAD modelled additions and insertions; they act as digital post-it notes from the traditional craftsman to the digital designer. In this example the original wooden form has SLS nylon grafts applied to its surface before a silicone mould is taken for a final translucent rubber cast. In a further example the original wooden form is scanned, replicated in CAD software then machined from black plastic using a 3-Axis CNC machine.
The final gloss black object and translucent cast are then re-scanned to test their 'invisibility' to the scanning process that created them.
