Cycles are the core principal of the universe, and are all pervasive. We are thoroughly enmeshed in cycles and the periodic rhythms, which span the frequencies of space and time. Some are of the most obvious on a daily basis: our sleep patterns, the weather, the seasons, sunrise, sunset, the moon phases, and more. On a larger magnitude: the age of our bodies, the rise and decline of species, the life cycle of stars. On a smaller, our breathing rate, our heart rate, the audio spectrum of music, speaking, the visible light spectrum, radio waves, cosmic rays, and ultimately the smallest measurable amount of time we can comprehend (Planck time). The appearance of the entire world and all existence with its natural and technological cycles are rooted in archetypal, sinusoidal principals.
Photogrammetry is the process of creating 3D objects from 2D photographs. The process can be used to scan anything from objects and people, to architecture, terrain and landscapes. There are various strategies you can use when taking photos to produce accurate models. This document includes photography techniques, ideal camera settings and lighting, photogrammetry software, and further resources to create 3D models from photos.

Photogrammetry[noun] The science or technique for obtaining reliable information on the natural environment or physical objects by recording, measuring and interpreting photographic images.
“gramma” (something written or drawn)
A map, a drawing, a 3D model of a real-world object, scene, or terrain.
Remote Sensing, GIS, Stereoscopy
Main Tasks of Photogrammetry
To measure something without touching it
To measure something that may no longer exist, or may only exist in photographs
To measure something too large to measure with traditional methods, i.e., landscape, a megalithic structure
Quantitative data from photographs, the science of measuring in photos.
Comparison to Laser Scanning (LIDAR)
Laser scanning is great in cases where photogrammetric techniques often fail – such as when objects have low texture, or shiny/reflective. However, laser scanning is expensive, time consuming, and can’t be used with moving objects like Photogrammetry can. That said, Laser Scanning and Photogrammetry can be considered complimentary to eachother.

1046 BC - 256 BC Discovery and capture of natural optical phenomena. Perforated gnomons projecting a pinhole image of the sun were described in the Chinese Zhoubi Suanjing writings. Some ancient sightings of gods and spirits, especially in temple worship, are thought to possibly have been conjured up by means of camera obscura projections.
Twilight Engines with artist Vishal K Dar is a part of an ambitious global project: Edge of See. The app activates a series of site-specific sculptures that push our senses of vision, scale, motion, and time. Dar brings his primary question — What is the edge of sight? — to the abandoned structures of the Marin Headlands, using technology to overlay former military batteries with these “engines”. The app augments the disconnect between the site’s past and present to insert sculptural experiences that change the way the viewer sees, thinks about, and relates to the location. Moving through the liminal spaces of military sites and screen, Dar’s “engines” unlock a world of other realities.
