Modelling with distributed spaces
Photograms – At the start of the 3D digital, Photogrammetry modelling process, a single still photograph is ‘stitched’ to another; this ‘action’, is repeated until a multiple alignment of images forms an image circle. In order to permanently fuse this newly shaped arrangement, the images pass through a two-part cloud formation process – first part ‘point’, followed by a ‘dense’, second stage ‘mesh’ sequence. By drawing parallels with natural occurring phenomena, the terminology ‘cloud’ and ‘mesh’, allows us to pre-visualise a non-visible computation sequence. This process has multiple, cross-disciplinary applications for both capturing and modelling objects, people and spaces. The open/source technology might be a useful tool for distributed cultural, community spaces in São Paolo and was introduced in the Photogrammetry Workshop delivered during two events and follow up visits to cultural spaces in December in 2017, ‘Distributed Spaces 1: Favelas Arise’ and ‘Distributed Spaces 2: Occupied Houses Convene.’
Workshops – During our workshops and through our shared exchange, more often sat in a circular or square configuration our attention was drawn to the importance of each square metre of floor that were using. On each of our visits we made a very short image capture of the areas of ground that we exchanged across. These were processed into Photogrammetry models that documented the grounds of our exchange. In total there are nine, we are aware that due to the perpetual threat of eviction and displacement that each group introduced us to, that these grounds might have already been lost.
Future Work – By revisiting the first processing stage of Photogrammetry, when one image is ‘stitched’ to another and through linking this technical process, with the situation of distributed spaces across São Paulo. Photogrammetry could be used to document small sections of the grounds, recording the spaces that facilitate exchange; similar to the technical alignment of one image with another; each of the modelled floors could be configured into one continuous ground. During the second mesh formation stage, when viewed on a computer screen the mesh appears as a multiple alignment of faces with each vortex linking to form an expanded mesh network.
We hope that the Mazi network builds and by capturing the grounds that each group meets upon; having a visualising system that links them together, could become an integral application of the Photogrammetry tool and allow for the grounds to be permanently virtually aligned.
