This document discusses computational design and generative design processes. It begins by defining computational design as algorithmic, procedural, generative, or rule-based approaches to design that focus on developing interactive design processes rather than static designs. Generative design is then discussed in more detail, including definitions, techniques like parametric and combinatorial methods, and properties of generative systems. Visual programming languages and tools for computational design are also introduced, such as Processing, Dynamo, and Grasshopper. The document provides an overview of key concepts and techniques in computational and generative design.
A talk from the http://www.republika.io conference:
You may have heard about recent reports and the debates on gun parts that are printed on a "3D printer". You may have heard about the RepRaps - the home built replicating 3D printers. You may have heard of NASAs plans to send a 3D Printer up to the moon to print out a moon base out of moon dust. You may argue, that this is old trick, since the ability to print out objects made of plastic and other materials have been around for more then a decade. Yet behold. I will prove to you that 3D printing will change absolutely everything. And with that change, a revolution will come, as we (our laws, our welfare systems, our society) are caught unprepared. (As a politician and a geek I will concentrate on the cool stuff, and not tune into the doomsday prophecies chants)

Implementation of a Simulation Model Using the Systems Dynamics: Case Study f...IJERA Editor
Â
With computer technology reaching the construction industry, much has changed in the way that these are
idealized and designed. Currently, with the increasing availability of tools for the development of the models and
parametric models intended for digital manufacturing, the insertion of these characteristics as design tool allows
the designer to test solutions on various factors that permeate the design process, especially as regards the
constructive points. The experience of the parameterisation dynamics and the dynamics of digital manufacturing
from the design of the project allows the development of complex geometries, since the control their properties
the analyses of structural variables of environmental comfort and aesthetics. The growth of the complexity of the
projects and the capacity of computing resources, has arisen the need to use a more systemic approach, as well as
have emerged the simulation programs based on dynamic systems, a digital simulation methodology in order to
understand complex forms, which is part of the concept of systemic thought for the resolution of problems. The
objective is in this Article is to identify and analyse the aspects of potential simulation based on dynamic
systems and demonstrate a practical case drawn up in Dynamo software.

Digital architecture manifesting an accurate virtual built environmenteSAT Journals
Â
Abstract âGod lives in detailsâ â it be the aspect of an intricate construction detail or an attribute assigned to a 3D model, all it matters is
bringing out the most accurate interpretation of architectâs thought process. The best medium for communicating the virtually
manifested ideas from concepts to the analytical research can be âa visualâ. Providing a visual in the form of a sketch, drawing,
perspective or an analytical report, used to depend only on the ability of manual presentation skills of the architect or designer.
The clientâs provocation in knowing the possible outcome as realistic as possible validates the anticipations former to execution
igniting and intensifying the challenge of producing more accurate presentable visuals by an architect. Computer aided design
tools and certain software facilitates beautified, presentable, streamlined, accurate, professional interpretation of architects
ideas, manifested thought processes using many tools such as a drawing, logical or analytical simulators, etc. that contribute in
creating the virtual reality at its most possible accuracy levels. Software is a communicator of the resource capital of design, i.e.
âArchitectâs ideaâ, and facilitates in visual perception of all the other stakeholders. The bits and bytes of various idea sparks by
an architect can be programmed on a logical platform with various software languages to produce a âvisualâ on the silicon
screen. Architectural design process is both common and unique for a student, academician, research anticipator or a
professional, ranging from concept to the final presentation outcome. This paper gives a consolidated account of various
softwares that can ease out the manifestations of thoughts on a digital platform for producing more accurate and presentable
interpretations.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Â
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
⢠The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
⢠The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate âany matterâ at âany timeâ under House Rule X.
⢠The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
A Strategic Approach: GenAI in EducationPeter Windle
Â
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

5. Generative design
âGenerative Design is a morphogenetic process using algorithms structured as non-linear
systems for endless unique and unrepeatable results performed by an idea-code, as in
Natureâ Celestino Soddu, 1992
âGenerative design is not about designing a building. Itâs about designing the system that
designs a building.â Lars Hesselgren, Director of KPF Research (cit. in Stocking, 2009)
Algorithmic systems are at the foundation of all Generative Systems. Stiny and Gips (1978a)
defined an algorithm as an explicit statement of a sequence of operations needed to perform
some task. Computation is the act of performing those operations.
:Computational Design and
Digital Fabrication GD
6. Design method in which the output, image, sound, architectural models, animation , is
generated by a set of rules or an algorithm, normally by using a computer program.
Generative design has: A design scheme , A means of creating variations, A means of
selecting desirable outcomes.
The development of information environments such as the world wide web show an
accelerated evolution and adaptation when compared to more traditional media such as the
printed page.

Digital Fabrication GD
7. Properties of Generative Systems
⢠The ability to generate complexity, many orders of magnitude greater than their
specification.
⢠The complex and interconnected relationship between organism and environment.
⢠The ability to self-maintain and self-repair
⢠The ability to generate novel structures, behaviors, outcomes or relationships.
Methodologies for Generative Design
⢠Self-organization and self-assembly
⢠Evolutionary Systems
⢠Generative grammars

⢠Substitution (L System , shape grammars),
⢠Agent based (artificial life swarming),
⢠Mathematical ( Description by equation, algorithm),
⢠Special partitioning (recursive Subdivision of space, voxels) ,
⢠procedural shape languages ( such us reptile),
⢠Parallel descript computation ( Polyautomata, Cellular automata)
:Computational Design and
Digital Fabrication GD
10. Generative design
Most generative design, in which the output could be images, sounds, architectural
models, animation etc., is based on algorithmic and parametric modelling. It is a fast
method of exploring design possibilities that is used in various design fields such as Art,
Architecture, Communication design and Product design.
Generative design is becoming more important, largely due to new programming
environments (Proceessing, Vvv, Quartz Composer, Open Frame Works) or scripting
capabilities ( Grasshopper, Dynamo, Scriptographer) that have made it relatively easy, even
for designers with little programming experience, to implement their ideas. But it can
also be related with data driven architecture. Parametric architecture includes both program
generated and data-driven software.
The feedback loop: Generative methods have their roots deep in the system dynamics
modelling and are by nature repetitive processes where the solution is developed during
several iterations of design operations.
:Computational Design and
Digital Fabrication GD
11. In traditional design, the role of the designer is to explore a solution space. Solutions may be
aesthetic, semiotic, cultural, dynamic, industrial, corporate, political, or any combination of
these and other determinants. The key relationship between designer and artefact is a
direct one (even if mediated via some third-party or medium). There is a direct relationship
between the designerâs intentions and that of the designed artefact. In contrast, design using
generative methods involves the creation and modification of rules or systems that
interact to generate the finished design autonomously. Hence, the designer does not
directly manipulate the produced artefact, rather the rules and systems involved in the
artefactâs production. The design process becomes one of meta-design where a finished
design is the result of the emergent properties of the interacting system (McCormack & Dorin
2001).
:Computational Design and
Digital Fabrication GD
12. âGenerative design mimics natureâs evolutionary approach to design. Designers or engineers
input design goals into generative design software, along with parameters such as
materials, manufacturing methods, and cost constraints. Then, using cloud
computing, the software explores all the possible permutations of a solution, quickly
generating design alternatives. It tests and learns from each iteration what works and
what doesnât.â
Quickly generate high performing design alternatives, many that designers would never never
think of on their own, from a single idea.
:Computational Design and
Digital Fabrication GD
13. In computing, a visual programming language (VPL) is any programming language that lets
users create programs by manipulating program elements graphically rather than by
specifying them textually. A VPL allows programming with visual expressions, spatial
arrangements of text and graphic symbols, used either as elements of syntax or secondary
notation. For example, many VPLs (known as dataflow or diagrammatic programming) are
based on the idea of "boxes and arrows", where boxes or other screen objects are treated as
entities, connected by arrows, lines or arcs which represent relations
Example:
Design By Numbers was created for visual designers and artists as an introduction to computational design. It is
the result of a continuing endeavor by Professor John Maeda to teach the âideaâ of computation to designers and
artists.
It is his belief that the quality of media art and design can only improve through establishing educational
infrastructure in arts and technology schools that create strong, cross-disciplinary individuals.
DBN is both a programming environment and language. The environment provides a unified space for writing and
running programs and the language introduces the basic ideas of computer programming within the context of
drawing. Visual elements such as dot, line, and field are combined with the computational ideas of variables and
conditional statements to generate images.

14. Visual Programing
Processing is an open source computer programming language and integrated development
environment (IDE) built for the electronic arts, new media art, and visual design communities
with the purpose of teaching the fundamentals of computer programming in a visual
context, and to serve as the foundation for electronic sketchbooks.
Dynamo, the application, is a software that can be downloaded and run in either stand-alone
"Sandbox" mode or as a plug-in for other software like Revit or Maya. It is described as: A
visual programming tool that aims to be accessible to both non-programmers and
programmers alike
Grasshopper is a visual programming language and environment developed by David Rutten
at Robert McNeel & Associates, that runs within the Rhinoceros 3D computer-aided design
(CAD) application. Programs are created by dragging components onto a canvas. The outputs
to these components are then connected to the inputs of subsequent components.

26. Syntax for Formulas Revit architecture
Formulas support the following arithmetic operations: addition, subtraction,
multiplication, division, exponentiation, logarithms, and square roots.
Formulas also support the following trigonometric functions: sine, cosine,
tangent, arcsine, arccosine, and arctangent.
The valid formula abbreviations for arithmetic operations and trigonometric
functions are
â˘AdditionĂł +
â˘SubtractionĂł -
â˘MultiplicationĂł*
â˘DivisionĂł/
â˘ExponentiationĂł^: x^y, x raised to the power of y
â˘LogarithmĂłlog
â˘Square rootĂłsqrt: sqrt(16)
â˘SineĂł sin
â˘CosineĂł cos
â˘TangentĂł tan
â˘ArcsineĂła sin
â˘ArccosineĂł acos
â˘ArctangentĂł atan
â˘e raised to an x powerĂł exp
â˘Absolute ValueĂł abs
27. Syntax for Formulas Revit architecture
You can enter integers, decimals, and fractional values in formulas, using
normal mathematical syntax, as shown in the examples below:
â˘Length = Height + Width + sqrt(Height*Width)
â˘Length = Wall 1 (11000mm)+ Wall 2 (15000mm)
â˘Area = Length (500mm) * Width (300mm)
â˘Volume = Length (500mm) * Width (300mm) * Height (800 mm)
â˘Width = 100m * cos(angle)
â˘x = 2*abs(a) + abs(b/2)
â˘ArrayNum = Length/Spacing
Parameter names in formulas are case sensitive. For example, if a
parameter name begins with a capital letter, such as Width, you must enter
it in the formula with an initial capital letter. If you enter it in a formula
using lower-case letters instead, for example, width * 2, the software will
not recognize the formula.
Note: It is recommended that you do not use a dash (-) when naming
parameters.
You can use conditional statements in formulas to define actions in a family
that depend on the state of other parameters. With conditional statements,
the software enters values for a parameter based on whether a specified
condition is satisfied. Conditional statements are useful in certain
circumstances; however, they make families more complex and should be
used only when necessary.
28. Syntax for Formulas Revit architecture
For most type parameters, conditional statements are unnecessary because
the type parameter itself is like a conditional statement: If this is the type,
then set this parameter to a specified value. Instance parameters are a
more productive place to use conditional statements, particularly when they
are used to set a parameter that does not vary continuously.
Syntax for Conditional Statements
A conditional statement uses this structure: IF (<condition>, <result-if-
true>, <result-if-false>)
This means that the values entered for the parameter depend on whether
the condition is satisfied (true) or not satisfied (false). If the condition is
true, the software returns the true value. If the condition is false, it returns
the false value.
Conditional statements can contain numeric values, numeric parameter
names, and Yes/No parameters. You can use the following comparisons in a
condition: <, >, =. You can also use Boolean operators with a conditional
statement: AND, OR, NOT. Currently, <= and >= are not implemented. To
express such a comparison, you can use a logical NOT. For example, a<=b
can be entered as NOT(a>b).
29. Syntax for Formulas Revit architecture
The following are sample formulas that use conditional statements.
Simple IF: =IF (Length < 3000mm, 200mm, 300mm)
IF with a text parameter: =IF (Length > 35', ĂŹString1ĂŽ, ĂŹString2ĂŽ)
IF with logical AND: =IF ( AND (x = 1 , y = 2), 8 , 3 )
IF with logical OR: =IF ( OR ( A = 1 , B = 3 ) , 8 , 3 )
Embedded IF statements: =IF ( Length < 35' , 2' 6" , IF ( Length < 45' , 3'
, IF ( Length < 55' , 5' , 8' ) ) )
IF with Yes/No condition: =Length > 40 (Note that both the condition and
the results are implied.)
Examples of Conditional Statement Usage
Typical uses for conditional statements in formulas include calculating array
values and controlling an elementĂs visibility based on a parameter value.
For example, you can use conditional statements to
â˘Prevent an array parameter from taking a value less than 2.In Revit
Architecture, arrays can only have an integer value of 2 or greater. In some
situations, it may be useful to create a conditional formula that maintains
an array parameter of 2 even if the calculated value is 1 or 0. With such a
formula, if the calculated array value is 2 or greater, the formula retains the
value. However, if the calculated value is 1 or 0, the formula changes the
value to 2.
30. Syntax for Formulas Revit architecture
â˘Formula: Array number = IF (Arrayparam < 2, 2, Arrayparam)
â˘Make muntins visible only when the number of window lights is greater
than 1.For example, if you have a Lights parameter that you want to use to
control the visibility of muntin geometry, you can create a Yes/No parameter
like MuntinVis, and assign it to the Visible parameter on the Properties
palette for the muntin geometry. Because the MuntinVis parameter is a
Yes/No (or Boolean) operation, both the condition (IF) and the results are
implied. In this example, when the condition is met (true), the MuntinVis
parameter value is selected, and the muntin geometry is visible. Conversely,
when the condition is not met (false), the MuntinVis parameter is cleared,
and the muntin geometry is not visible.
â˘Formula: MuntinVis = Lights > 1

Mouse 1D.
Move the mouse left and right to shift the
balance. The "mouseX" variable is used to control
both the size and color of the rectangles.
void setup() {
size(640, 360);
noStroke();
colorMode(RGB, height, height, height);
rectMode(CENTER);
}
void draw() {
background(0.0);
float r1 = map(mouseX, 0, width, 0, height);
float r2 = height-r1;
fill(r1);
rect(width/2 + r1/2, height/2, r1, r1);
fill(r2);
rect(width/2 - r2/2, height/2, r2, r2);
}
