15-112: placeHolder (2020)
A wide variety of 3D scanning technology exists today that use a series of images to
construct a form based on the content of the images. This project situates itself on an edge of
those, allowing the user to generate a 3D model from 360-degree images through online
databases.
Much other software including Autodesk Recap, Multi-view environment, and
Meshroom all serve to generate geometry from image distances. In fact, human’s perception of
space uses the same underlying logic as all these programs. The slight differences in images
sent to our brain from our eyes tells us what is near and what is far.
The project, titled placeMaker, was an exploration of photogrammetric techniques
written from-scratch with Python. It is an inquiry into quick generation of site geometry
(buildings, roads, etc.) for use in site mapping and architectural design. First, the user selects
two 360-degree panoramic images either from google maps or elsewhere. Then, placeMaker
interprets the selected images and detects edges. Finally, the program cross-references the
images to place them in 3D space and allows the user to fly through and examine the
projected geometry.
