Computer models of world heritage sites

Since 2016, I have built digital models of world heritage sites. Through digital models, architecture’s audience can expand beyond in-person visitors. A few of my creations are below:

.

Models can reveal aspects of construction and design that are otherwise invisible. Amiens Cathedral and the Kaaba in Mecca illustrate this. The view of the Kaaba from above is only possible through computer models, due to religious restrictions on flying above the Kaaba. The view of Amiens Cathedral from underground is another example. My model suspends the cathedral in mid-air.
I can also strip away later changes or decay. Details include people, street furniture, and neighboring buildings. Jerusalem’s Dome of the Rock and Al-Aqsa Mosque (which are surrounded by trees and Roman-era walls) or Amiens Cathedral (surrounded by the modern city) are two examples. Models also permit me to restore structures to their original appearance, such as this model of the Parthenon.

Destruction of the James Street Commons: 1975-2020

This map illustrates buildings demolished in one Newark neighborhood, the James Street Commons. When historians first considered this neighborhood for landmark status in 1975, there were 425 historic buildings.  Even after earning landmark status in 1978, demolitions and urban decay continued. Rutgers, Edison Parking, St. Michael’s Hospital, and the New Jersey Institute of Technology have demolished dozens of old buildings, mostly to construct surface parking lots as an “interim” land use. It is time that the local and state governments be more proactive in preserving the city’s housing stock.

This ink and watercolor drawing shows every building, window, and architectural detail on campus. The number of windows on each façade are faithful to reality. There are at least 2,000 windows. The perspective was formed from Google Earth satellite and street view images. The image measures 26 by 40 inches and is framed in my dorm room. I wanted to create a souvenir of my four years at Columbia. Years from now, I will look at this image and remember.

Columbia in a Box

.

Before my first year at Columbia University, I assembled this tiny model of the campus out of painted and folded paper. Each building was measured out on a flat sheet of paper, decorated, painted, cut out, and then folded. Each building is made with no more than one sheet of paper. This creation folds out of a vintage cigar-box. Dimensions: 5 inches wide, 9 inches long, and 3 inches deep.

Evolution of the English Country House

Developed with Paul Barnwell, historian at the University of Oxford

.

Music: Piano Trio in E Flat, Op. 100 by Franz Schubert

.

This animation traces changes to English country house design between 1660 and 1715. In 1660, the typical Elizabethan style country house was compact, fortified, and square. By 1715, the emerging Baroque and Palladian country house was spread out, less compact, and better integrated into the rural landscape. The gardens became an extension of the house. This animation illustrates the aesthetic and architectural changes during this era.

Amiens Cathedral Construction Sequence

Supervised by Stephen Murray, historian at Columbia University
Presentation delivered March 2018 at St. Catherine’s College at the University of Oxford

.

My goal is to recreate Amiens Cathedral digitally. My method is to build an interactive and open-source computer model of the entire cathedral that is accurate to the foot and photo-realistic. This project would be impossible without the guidance of medievalist Stephen Murray, who introduced me to Amiens in his fall 2016 seminar at Columbia University.

Construction Sequence: 1175-1475

While studying history at Oxford University, I based my final research project on Burford Church near Oxford, England. With the generous help from Cathy Oakes, I visited this humble parish church and recreated its 300 year construction and evolution through a computer model. View the resulting animation above or download the digital source files for free at this link. Narration below:

.

  • c.1175 – Work begins on the Norman church working from east to west.
    It is a simple structure with round Norman windows and a choir, nave, and tower.
  • c.1200 – Demolition to construct a chapel, aisle, and entrance foyer.
  • c.1250 – Addition of north and south transept. Chancel is expanded.
  • c.1400 – The crypt is added, and the tower is heightened. The architectural style changes from Norman to Gothic, from round arches to pointed. Local cloth merchants construct a separate guild chapel at a slight angle to the main church.
  • c.1475 – Guild chapel is demolished to build the Lady Chapel. Most of the remaining nave is demolished to construct two new aisles, a larger west window, and new clerestory windows. Two chapels are added to either side of the choir, as well as a three floor entrance tower (not visible from this angle).
  • This completes the construction of Burford Church.

Visual Analysis

What is the visual language of Burford Church? What aspects of medieval social history can be deduced from the church decoration? Without written historical records, building fragments alone can tell the story of church construction.
Here is my tour of the architectural fabric.

Zoning and Affordable Housing in Newark

Featured June 2017 in this NJ.com news article about my computer simulation

.

.

In the summer of 2017, I helped oppose the gentrification and rezoning of a neighborhood in my city. The area was zoned for buildings no higher than eight stories, which was respectful of the small and community scale of the existing structures. City officials, however, proposed rezoning a large section of the area  to permit structures up to eighteen story structures – four times taller than any other structure in the immediate area.
Motivated by profit, the J&L Parking Corporation lobbied the city to increase the maximum allowed height on their land. Though they had little intention to build anything, this zoning change would increase the value of their property when they decided to sell it in the future. In what is called “spotzoning,” the zoning changes were drawn to exclusively benefit J&L’s properties and the parking lots of the nearby Edison ParkFast corporation.
I created a computer simulation of how the area would appear if the proposal passed and the neighborhood was built up to the maximum density allowed by law . This computer simulation was shown to city officials to inform the planning process.

City Council Speech

September 19, 2017

.

.

I’d like to speak on why opposing MX-3 is consistent with supporting inclusionary zoning.
To my knowledge, 7 members of the City Council voted in favor of inclusionary zoning. This is an important move to protect our city most vulnerable residents and to preserve affordable housing in our downtown.
MX-3 and upzoning will jeopardize this important piece of legislation.
Why?
inclusionary zoning kicks in when (firstly) developers build structures over 30-40 units and (secondly) they request a variance to build this structure.
When an area is zoned for larger and taller structures developers can build more and larger structures WITHOUT requesting a variance to build larger. And when developers do not need to request a variance for height, it is less likely they will need to include affordable housing in their project.
In effect, MX-3 will remove the requirement to build affordable housing in the effected area. When zoning is overly generous to developers and zoning permits overly large scale, develops do not need variances. And when developers don’t need variances, they do not have to built affordable housing.
In addition, since MX-3 could be expanded to anywhere within a half mile radius of Penn Station, it is quite possible that MX-3 could be expanded in the future. In effect, this would eliminate the requirement for developers to build affordable housing in this area. Upzoning does not benefit affordability.
Secondly, what is sustainability?
Sustainability and transit-oriented development is not just about a short distance to Penn Station. It is not just about green roofs or any type of development.
Sustainability is about affordable housing that we the people can afford to live in. We don’t want luxury condos for the 1% in the MX-3 area. We want development that our residents and you can afford.
All of us can agree that WE ALL WANT DEVELOPMENT. But we want development that is 1. Affordable 2. Respectful of the Ironbound community. And 3. Respectful of our city’s diversity and history.
MX-3 is none of these things. It is about landbanking and benefiting the 1% wealthiest outside our city. I encourage you to strike down MX-3 and to encourage instead an open dialogue with the community about SUSTAINABLE and AFFORDABLE development in our city.
Developers should come to Newark and development should happen. However, we should not upzone entire sections of our city, in effect removing the requirement for affordable housing, undermining the inclusionary zoning we just created, and jeopardizing the recent master plan we created with public participation.

3. Cathedral Flythrough

Viewers approach Amiens from the west, like medieval pilgrims did. Viewers then move through the complex system of flying buttresses that support the cathedral vaults. The animation then reconstructs the dynamic geometry that engineers encoded in the cathedral floor plan. The film closes with the view from below the foundations, as if the cathedral were floating on air.

amiensAlong with the Parthenon, Amiens Cathedral is introduced each semester to students in Art Humanities. This seminar has been taught since 1947 and is required of all undergraduates as part of the Core Curriculum. Through broad introductory courses in art, literature, history, music, and science, the Core aims to produce well-rounded citizens of Columbia University students. Amiens was chosen as representative of all Gothic architecture, and as a lens through which to teach skills of visual analysis. This computer model I created instructs over 1,300 students per year.
Based on the computer model, I produced the three short films above: (1) a construction sequence, (2) a digital flythrough of the finished cathedral, and (3) a speculative animation of the cathedral in cross section. This trilogy is complemented with music from Pérotin (the thirteenth-century French composer) and Josquin des Prés (the fifteenth-century composer). Both musicians also happen to be featured in the Music Humanities component of the Core Curriculum.
My objective is to digitize and re-imagine Amiens. To borrow a quote from Viollet-le-Duc, the legendary nineteenth-century preservationist-architect of Notre-Dame de Paris, my aim was “to restore the building to a state of completeness that may have never existed.” For instance, Amiens lost almost all of its original stained glass windows and large parts of its nave. My project responds by presenting the cathedral in an idealized light. Awkward walls, later additions, and anachronistic features can all be airbrushed away from my model, so as to reveal how the master masons originally envisioned their cathedral in the thirteenth century.
A building is experienced as a sequence of sights and sounds. A research text about such a building, however, can only capture limited information. Photography, film, and computer simulations are, in contrast, dynamic and sometimes stronger mediums to communicate the visual and engineering complexity of architecture. This project seeks to capture dynamic Amiens through a visual, auditory, and user interactive experience. Through film, one can recreate and expand the intended audience of this architecture, recreating digitally the experience of pilgrimage.
In Viollet-le-Duc’s 1863 book, Entretiens sur l’architecture, he presented Gothic architecture as the synthesis of a Roman basilica and a Romanesque church. After several centuries of evolution, these two forms merged into the singular form of the Gothic cathedral. For him, the Gothic cathedral (particularly Amiens) was the pinnacle of human architectural and aesthetic achievement. In other words, the cathedral’s form and plan evolved in response to theology and changes in the rituals of the Mass.
The two animations below illustrate Viollet-le-Duc’s thesis about Gothic. Although later scholars dispute his simplistic analysis, his work remains influential.

Cathedrals and History

In the absence of surviving written records, many scholars read cathedral construction as a proxy for economic growth, or as a symbol for the structure of medieval society. The decision of where and when to start building a cathedral was tied to the right economic and political conditions. The large majority of cathedrals were built in the region of Northeastern France during the High Middle Ages – during a period of remarkable economic growth and productivity in the thirteenth century. Construction slowed after climate change caused failed crops, followed by the Great Famine (1315) and the Black Death (1350). The economic conditions and cathedral construction never rebounded for a long time afterwards, and when construction did rebound, Europe had entered the Renaissance with a new aesthetic sensibility different from Gothic Amiens
The cathedral can also be read as a political symbol. Funding came from a combination of donations, indulgences, and taxes on church-owned farmlands. The logic between competing regions and feudal kingdoms in medieval France reads something like: the larger and prettier the cathedral, the larger and more powerful the city and sponsors behind it. For many of these towns, the size of the cathedral was well out of proportion to the actual size of the town. Amiens, for instance, was one of the largest cathedrals in Europe for a town of ~26,000. The other cathedral town of Chartres was, similarly, competing with Paris for power and independence. Cathedral were architectural symbols for the competitions between cities and regions. In this light, the cathedral became as much a religious space as a political statement of civic identity.

Method

Anyone can download this model from Sketchup for free and edit it from their computer. Over 3,000 people have downloaded this model, and numerous others have 3D printed it as part of their architecture studios. This model is built with free computer modeling software called Sketchup. Among software, Sketchup is easiest to learn. Within minutes, students and teachers unfamiliar with Sketchup can build their own models with ease. In response to several rounds of edits and suggestions from Stephen Murray, I finished this model and exported the animation for final edits and special effects.
In this recorded lecture, I describe the workflow and editing process behind this project.
