Concrete structures that remind me of UCSD-concrete, dirt, occasional trees, and glimmers of steel accents in the buildings. Cha-chowww!
Precise Images of Buildings That 3D Scanning Enables by Scott Page Design
3D scanning—though it’s been around since the 1960s—has been in the news of late, with Harvard using the technology to recreate ancient statues and MakerBot announcing a desktop scanner last month. But cheaper, faster, and more accessible 3D scanners aren’t just revolutionizing how we print terrifying models of our own faces. They’re also changing how we understand the city.
A fascinating story about urban-scale 3D scanning published on the Atlantic Cities this week explores how a Bay Area architect named Scott Page is using a 3D scanner to generate super-accurate models of historic and dilapidated buildings.
Page’s system takes a series of photographs and patches them together based on how light bounces off each surface. Rather than taking weeks to survey an old building, architects can now generate precise dimensions in just a few hours. Because the scanner uses color photographs, the models are also incredibly beautiful, expressive documents—Page compares them to the first photographs ever made. “There is a magical quality to point cloud imagery, similar to the earliest photos that froze time onto small metallic plates,” he writes on his website.
- Reconstruction by Philippe Froesch
This reconstruction is rather different than those seen in the previous post. The nose is much narrower and the nostrils are much less flared. The supraorbital torus is less prominent, the eyes are light and the skin much fairer too. It also seems less prognathic but it’s hard to tell from these angles. You don’t often see a reconstruction of any hominid dating to ~1.8 Mya that looks this modern human caucasian-like. However, Homo erectus was all over the shop and certainly variability existed. Here are some examples of other reconstructions, this one (Dmanisi), this one (Dmanisi), this one (Homo erectus) and this one (Homo erectus). See also this image for comparisons of different reconstructions of the Dmanisi specimens. I wonder about variability both in artistic but scientifically informed representation and on a geographic basis in fossil specimens. And I’m aware that I’m conflating taxa here because as today’s guest post noted, there is no consensus as to the taxon of the Dmanisi fossils.
I just love all Leb Woods’ work…here’s another one of his. I wish I attended one of his lectures and met him before his death.
