California Waterscape

California Waterscape animates the development of this state’s water delivery infrastructure from 1913 to 2019, using geo-referenced aqueduct route data, land use maps, and statistics on reservoir capacity. The resulting film presents a series of “cartographic snapshots” of every year since the opening of the Los Angeles Aqueduct in 1913. This process visualizes the rapid growth of this state’s population, cities, agriculture, and water needs.

Text from animation is copied below:

.

Each blue dot is one dam, sized for the amount of water it captures. Each blue line is one canal or aqueduct. These infrastructure features become visible as they near completion.

.

The challenge: to capture and transport water to where water is needed hundreds of miles away. To grow food where there was once desert.

.

Notice the sudden growth spurt in construction during the 1930s Great Depression… And again during the 1950s through 1970s.

.

The longest aqueducts that run from mountainous areas to the cities mostly deliver drinking water. The shorter aqueducts in the Central Valley mostly bring water to farms.

.

Here we see dams in the Sierra Nevada Mountains gradually come on line. Many prevent flooding. Or they seize winter snow and rain for when this water is needed in summer.

.

Since the 1970s, construction slows down, but population continues growing.

.

In 2010, about six hundred fifty dams and four thousand five hundred miles of major aqueducts and canals store and move over 38 billion gallons per day. This is the most complex and expensive system ever built to conquer water.

.

But, how will man’s system cope with climate change?

3. Source Data on Dams and Reservoirs

^ Created with open data from the US Bureau of Transportation Statistics and visualized in Tableau Public. This map includes all dams in California that are “50 feet or more in height, or with a normal storage capacity of 5,000 acre-feet or more, or with a maximum storage capacity of 25,000 acre-feet or more.” Dams are geo-referenced and sized according to their storage capacity in acre-feet. One acre-foot is the amount required to cover one acre of land to a depth of one foot (equal to 325,851 gallons or 1.233 ● 10liters). This is the unit of measurement California uses to estimate water availability and use.

.

.

4. Source Data on Aqueducts and Canals

^ Created with open data from the California Department of Water Resources, with additional water features manually added in QGIS and visualized in Tableau Public. All data on routes, lengths, and years completed is an estimate. This map includes all the major water infrastructure features; it is not comprehensive of all features. This map excludes the following categories of aqueducts and canals:

.

  • Features built and managed by individual farmers and which extend for a length of only a few hundred feet. These features are too small and too numerous to map out for the entire state and to animate by their date completed. This level of information does not exist or is too difficult to locate.
  • Features built but later abandoned or demolished. This includes no longer extant aqueducts built by Spanish colonists, early American settlers, etc.
  • Features created by deepening, widening, or otherwise expanding the path of an existing and naturally flowing waterway. Many California rivers and streams were dredged and widened to become canals, and many more rivers turned “canals” remain unlined along their path. Determining the “date completed” or “date built” for these semi-natural features is therefore difficult. So, for the purposes of simplicity and to aid viewers in seeing only manmade water features in the animation, this category is generally excluded.

Computer Models of World Heritage

last updated 10 December 2018

.

Beginning in 2016, I became involved in building interactive computer models of world architecture and heritage. Through computer modelling, there is the possibility to broaden the audience of a work of architecture beyond the small number that may actually visit the building in person. World heritage sites or buildings of cultural importance are of particular aesthetic and research value as computer models can reveal qualities of their construction and design that are otherwise invisible to the naked eye. A few of these models I created are featured below:

.

.

Amiens Cathedral in France and the Kaaba in Mecca (Saudi Arabia) are two of the most cogent examples of the technical possibilities of computer models. By building a model that is accurate to the measured foot, one can then view the building from beneath, above, or from unique angles that are otherwise impossible for the public to view in person. The view of the Kaaba from directly above is one such view that is possible to simulate through computer models, but is impossible to view from in person. This is due to religious and legal sanctions against flying above the Kaaba. The view of Amiens Cathedral from directly below is another example. The computer model strips away the layers of earth beneath the foundation, thereby suspending the cathedral in mid-air and permitting an imaginary view which, while theoretically existing, is humanly impossible to view.

These same models also allow us to strip away unnecessary or obstructive additions to better appreciate specific aesthetic qualities of the building. Such details include people, street furniture, and neighboring buildings that block certain angles of view. The Dome of the Rock and the Al-Aqsa Mosque of Jerusalem (which are surrounded by trees and ancient Roman-era walls on all sides) or Amiens Cathedral (surrounded by the medieval and mostly modern urban fabric of the city) are two examples of this phenomenon. Similarly, models permit us to restore structure to their original appearance as originally intended to be viewed by patron and mason, such as this model of the restored Parthenon.

Overall, the possibilities and applications for modelling are growing, and the state of the field today is by no means static. Future developments in computing, internet speeds, virtual reality, and photogrammetry will certainly permit further advancements in this field of technical and academic research.

My objective is to recreate Amiens Cathedral as it appeared in the 15th century. My method described above and presented at St. Catherine’s College at Oxford University in spring 2018 is to build an computer model of the entire cathedral, accurate to the foot, photo-realistic, and fully interactive. My hope is to find new and creative ways to engage students and visitors with this architecture.
I am further expanding upon this work for my senior thesis and by building computer models for Columbia’s Media Center for Art History. I also created computer simulations for the Eiffel Tower’s construction sequence and of a small parish church in Burford, England.
This project would be impossible without the invaluable and expert guidance of my faculty mentor and medievalist Stephen Murray, who taught me in the Fall 2016 Bridge Seminar Life of a Cathedral.

Eiffel Tower – Animated Construction Sequence

This project is also reported on by the media company Invidious
.

 

The Eiffel Tower was built during 18 months – between August 1887 and March 1889. This film shows the construction sequence, starting with the foundations et ending with the completion of the cupola. I downloaded Sketchup to create the computer simulation, and the post-production was made with iMovie. This model and video represent about two days work, or twenty hours.

.

The source file for the model was downloaded here from the Sketchup 3D Warehouse, a database of free architectural models. Or, to view this model in virtual reality, please click here. The historic construction photos featured in this video were downloaded here from the Eiffel Tower’s Wikipedia page. And the blueprints consulted to create this animation are from a 2002 reprint of the Eiffel Tower structural plans.

Construction Sequence

At the conclusion of my year as an art history student at Oxford University, I chose to base my final research project on Burford Church in Oxfordshire County, England. This is a Grade I listed structure by English Heritage, roughly constructed between 1175 and 1475, with continued modifications in the Victorian era. With the generous supervision of my art history tutor, Cathy Oakes, I visited this humble parish church and constructed a computer model that documents the structure’s gradual construction and expansion over nearly 300 years work. I converted the finished model into a short, two-minute film, featured below. The original source files for this project can also be freely downloaded here from the “3D Warehouse“, a database of architectural models for the use of designers, historians, and researchers. The subtitles of this sequence are transcribed here:

.

Around 1175, work begins on the Norman church – a simple structure with choir, nave, and tower between. Here we see the structure being erected from east to west. Notice the round Norman windows.

By 1200, a small side chapel is added to the south of the tower. An aisle and entrance foyer on the south are also added. These changes require demolishing part of the existing structure.

By 1250, the side chapel is demolished and replaced by a north transept, south transept and expanded chancel.

By 1400, a crypt is added and the tower extended up. At this point, the architectural style changes from Norman to Gothic – from round arches to pointed.

The local cloth merchants also construct a guild chapel – detached from the main church and built at a slight angle.

By 1475, the guild chapel is partially demolished. On its foundations the Lady Chapel is built.

Meanwhile, most of the remaining nave is demolished to construct two aisles on either side of the nave, a larger west window, and new clerestory-level windows.

Two chapels are added on either side of the choir as well as a 3-story entrance tower. Neither of these additions are visible from this angle.

This completes the construction sequence of Burford Church.

We are now circling around the church – working our way clockwise.

Visual Analysis

The film below is a brief visual analysis of the church’s architectural fabric. Through my analysis, I seek to understand the following: What is the visual language of Burford Church? What aspects of medieval social and cultural history can be deduced from the church’s decoration? And, in the absence of a written historical record, how can we detect the sequence in which the church was erected on the basis of architectural fragments alone?

Research Abstract

.

amiensAs the apotheosis of Gothic architecture built during the 13th century, Amiens Cathedral is a dynamic and living structure. As the ninth largest Gothic cathedral in the world and one built in relatively short span of time, Amiens Cathedral exhibits remarkable stylistic unity throughout. Alongside the Parthenon, Amiens is taught each semester to several hundred students in Art Humanities. This has been a course required since 1947 of all undergraduate students in Columbia University’s Core Curriculum. This cathedral and the animations I created are currently used in classroom instruction of 1,300 students per year.

My objective is to recreate Amiens Cathedral as it appeared in the 15th century. My method is to build an accurate computer model of the entire cathedral, accurate to the inch, photo-realistic, and fully interactive. My hope is to find new and creative ways to engage students and visitors with this work of architecture.

The final video sequence is in two parts. One, a three minute construction sequence of the cathedral’s erection between 1220 and 15th century, which has been viewed over 30,000 times on YouTube. Two, an eight minute fly-through of the finished work of art. Viewers approach the cathedral through the narrow medieval city streets and circumnavigate the exterior from bird’s eye and ground level. Viewers then enter the cathedral and are guided through the complex interior spaces. This trilogy is complemented by historically appropriate music from 13th century French composer, Pérotin and 15th century composer Josquin des Prés, who is incidentally also featured on the Music Humanities component of Columbia’s Core Curriculum.

Amiens has undergone significant revisions and the destruction of almost all its original stained glass windows and large parts of its nave. Through digital modeling, it is possible to restore the structure to its idealized appearance as its initial architect intended. Through video, we can recreate and expand the intended audience of this building, recreating digitally the experience of pilgrimage. Through virtual reality, we can encourage new ways of engaging with art and architecture.

A building is dynamically experienced as a sequence of sights and rooms. A research text about such a building, however, can only capture a limited amount of a structure. Photography, computer simulations, and film are, by comparison, dynamic and sometimes stronger mediums to communicate the visual and engineering complexity of a building. This project seeks to capture that dynamism through a visual, auditory, and user interactive product.

Students can download this model and freely edit, revise, and explore from their personal computer. Over 2,000 students and scholars have downloaded and 3d printed this model, which is currently being used by students at Reading University (UK) to study acoustic archaeology. This model of Amiens Cathedral is built with free computer modeling software called Sketchup. Sketchup has a wide range of drawing applications, architecture, interior design, and civil engineering. And, for computer modeling software, it is easy to use. With just a few commands, such as draw, pull, animate, and toggle, students and teachers unfamiliar with the program can build their own models in minutes.

Watch the two films below, followed by links to explore this model in virtual reality. I am further expanding upon this work for my senior thesis and by building computer models for Columbia’s Media Center for Art History. I have also created computer simulations for the Eiffel Tower’s construction sequence and of a small parish church in Burford, England.

This project would be impossible without the invaluable and expert guidance of my faculty mentor and medievalist Stephen Murray, who taught me in the Fall 2016 Bridge Seminar Life of a Cathedral. This project is also featured here on Columbia University’s website. My video lecture about how I created these animation is published here.

Amiens Cathedral: A Guided tour

.

.

A guided tour of Amiens with music composed by Perotin: Viderunt Omnes, most likely composed in 1198, twenty-two years before construction started on Amiens. Viewers approach the cathedral from the west, as pilgrims would have in the Middle Ages. Viewers then circle above and through the complex system of flying buttresses that support the cathedral. The animation finishes by visualizing the cathedral from below the foundations in an abstract fashion. Starting from the concrete ground-level view of the pilgrim, the animation becomes increasingly abstract.

Computer modeling allows one to explore angles of view not possible in reality. Of particular beauty are the view of Amiens from below. With the layers of earth and foundation removed, one looks up the grid of vaults and the forest of columns. The view is simultaneously a plan of the cathedral and a worm’s eye view, simultaneously of a real cathedral and an imagined world.

Development of the Gothic Cathedral: An Evolution

.

Amiens is at an apex in the development of Gothic cathedrals. The earliest cathedrals were modeled after Roman basilicas with two narrow aisles on either side of a long, rectangular open space spanned with wood trusses. This is best exemplified in the plan of Old Saint Peter’s Basilica in Rome. Later Gothic cathedrals in following centuries modified this simple model. The dimensions and height of the cathedral grew, alongside the complexity of its vaults, columns, and ornaments. In short, the form and floor plan of the medieval cathedral evolved in response to changes in the use of the church and the rituals of the Mass.

Below are two animated videos illustrating the evolution of the Gothic cathedral: In cross section at left and in plan at right.

When I left home to attend college at Columbia University, I knew the tumultuous transition to college would leave me longing for my hometown of Newark. To remind me of my city and home, I painted this watercolor panorama of my city. Every night, before tumbling into bed, I gaze at this painting and visually trace the streets of my childhood and the buildings of my memories.
