April 24, 2017 iii Abstract A STUDY OF THE ADAPTATION OF PARAMETRIC COMPUTER DESIGN AMONG LANDSCAPE ARCHITECTURE PROFESSIONALS IN TEXAS Chad Allen Paulson, MLA The University of Texas at Arlington, 2017 Supervising Professor: Dr. Taner R. Ozdil Parametric design utilizes algorithmic-based software to produce computational, generative, responsive, and immersive three-dimensional models for use in landscape architecture, planning, and architecture (Cantrell & Holzman, 2016; Jabi, 2013). Advanced parametric software tools such as Rhinoceros and Grasshopper combine to create a robust system to express a set of customizable parameters that define and clarify the design intent and set of iterative solutions to a design problem (Jabi, 2013). iv Although parametric design in architecture has been in use for over 15 years, it has not been broadly adopted by the field of landscape architecture. Current professional practices illustrate that software development within the design fields, including landscape architecture, are strongly trending towards augmented reality, open source software and building information modeling systems (Bentley, et al. 2016). The purpose of this research is to understand the adaptation and implementation of the innovation of parametric design into the field of landscape architecture overall, then specifically to the practice and the speed with which the innovations are being adapted into landscape architecture firms in Texas. Research on this topic has the possibility to increase awareness of technological advancements in the practice and education of landscape architecture, architecture, and planning. In this study, the researcher documents the current understanding of parametric design in the practice of landscape architecture nationally and internationally through literature review, and then compares it to the practice in Texas by studying landscape architecture professionals’ perceptions on the issue. This research followed qualitative methods (Deming & Swaffield, 2011) to acquire the knowledge needed to understand the adaptation and implementation of the innovation of parametric design in Texas. In this study, this researcher conducted in-depth interviews to discover patterns in the acceptance or likely adaptation of parametric design in landscape architecture firms. The subjects were designers or managers of landscape architect firms that practice landscape architecture in Texas. The snowball technique was used to acquire the study population (Taylor & Bogdan, 1998). v Rogers’ theory, Diffusion of Innovation, was used to design questions to be used while interviewing landscape architectural professionals to determine their level of adapting innovation (Rogers, 1995; Deming & Swaffield, 2011) to their design practices. Themes were drawn from the interviews using the Diffusion of Innovation categories, to document the overall rate of adaptation to the process of parametric design experienced from the participants in the interviews. The responses are studied qualitatively to understand where each firm or landscape professional stands within its process of innovation (Taylor & Bogdan, 1998; Deming & Swaffield, 2011). In conclusion, this research assessed that adaptation is happening in landscape architecture firms in Texas, and summarizes its current usage and explores the technical, financial, and educational issues of adapting to these methods. The interviewees had a wide range of experience in professional management and practice. However, experience with emerging industry software and technology was more prevalent in the training of new staff then it is with upper management. Most firms agreed that technology changes are on the horizon, but there is no clear way of defining what that means for each practice using parametric design. vi TABLE OF CONTENTS Acknowledgements ........................................................................................................................ iii Abstract ........................................................................................................................................... iv TABLE OF CONTENTS .............................................................................................................. vii LIST OF ILLUSTRATIONS ........................................................................................................ xii Chapter 1 INTRODUCTION ........................................................................................................................... 1 1.1 Introduction ........................................................................................................................... 1 1.2.

  • Paper We Present an Early User Evaluation of a Advances in Sketch-Based Modeling Are Set to Simplify Many Sketch-Based 3D Modeling Tool We Have Been Developing [7,8]
    ARTICLE IN PRESS Computers & Graphics 31 (2007) 580–597 www.elsevier.com/locate/cag Calligraphic Interfaces An evaluation of user experience with a sketch-based 3D modeling system Levent Burak KaraÃ, Kenji Shimada, Sarah D. Marmalefsky Mechanical Engineering Department, Carnegie Mellon University, Pittsburgh, PA 15213, USA Abstract With the availability of pen-enabled digital hardware, sketch-based 3D modeling is becoming an increasingly attractive alternative to traditional methods in many design environments. To date, a variety of methodologies and implemented systems have been proposed that all seek to make sketching the primary interaction method for 3D geometric modeling. While many of these methods are promising, a general lack of end user evaluations makes it difficult to assess and improve upon these methods. Based on our ongoing work, we present the usage and a user evaluation of a sketch-based 3D modeling tool we have been developing for industrial styling design. The study investigates the usability of our techniques in the hands of non-experts by gauging (1) the speed with which users can comprehend and adopt to constituent modeling steps, and (2) how effectively users can utilize the newly learned skills to design 3D models. Our observations and users’ feedback indicate that overall users could learn the investigated techniques relatively easily and put them in use immediately. However, users pointed out several usability and technical issues such as difficulty in mode selection and lack of sophisticated surface modeling tools as some of the key limitations of the current system. We believe the lessons learned from this study can be used in the development of more powerful and satisfying sketch-based modeling tools in the future.

  • HCI Remixed : Essays on Works That Have Influenced the HCI
    4 Drawing on SketchPad: Refl ections on Computer Science and HCI Joseph A. Konstan University of Minnesota, Minneapolis, Minnesota, U.S.A. I. Sutherland, 1963: “Sketchpad: A Man–Machine Graphical Communication System” Sutherland’s SketchPad system, paper, and dissertation provide, for me, the answer to the oft-asked question: “why should HCI belong in a computer science program?” I fi rst came across the paper “SketchPad: A Man–Machine Graphical Communica- tion System” from the 1963 AFIPS conference nearly thirty years after it had been published (Sutherland 1963). I was nearing completion of my own dissertation in which I was exploring a variety of techniques for constructing user interface toolkits. At the time, the paper seemed little more than a handy reference in which I could trace the lineage of constraint programming in user interfaces—from Sketchpad, through Borning’s ThingLab (Borning 1981), to my own work, with various hops and detours along the way. I guess I was young and in a hurry. It was only a few years later when I started to teach this material that I realized how much of today’s computing traces its roots to Sutherland’s work. What was this tremendous paper about? A drawing program. Not just any drawing program, but one that took full advantage of computing, a million-pixel display (albeit with a slow pixel-by-pixel refresh), a light pen, and various buttons and dials to empower users to draw and repeat patterns, to integrate constraints with draw- ings so as to better understand mechanical systems, and to draw circuit diagrams as input to simulators.

Cambaa, Manuel Conterob, Pedro Companyc aUniversity of Houston. Houston, TX. [email protected] bUniversitat Politècnica de València. Valencia, Spain. [email protected] cUniversitat Jaume I, Castellón, Spain. [email protected] Abstract CAD model quality in parametric design scenarios largely determines the level of flexibility and adaptability of a 3D model (how easy it is to alter the geometry) as well as its reusability (the ability to use existing geometry in other contexts and applications). In the context of mechanical CAD systems, the nature of the feature-based parametric modeling paradigm, which is based on parent-child interdependencies between features, allows a wide selection of approaches for creating a specific model. Despite the virtually unlimited range of possible strategies for modeling a part, only a small number of them can guarantee an appropriate internal structure which results in a truly reusable CAD model. In this paper, we present an analysis of formal CAD modeling strategies and best practices for history-based parametric design: Delphi’s horizontal modeling, explicit reference modeling, and resilient modeling. Aspects considered in our study include the rationale to avoid the creation of unnecessary feature interdependencies, the sequence and selection criteria for those features, and the effects of parent/child relations on model alteration. We provide a comparative evaluation of these strategies in the form of a series of experiments using three industrial CAD models with different levels of complexity.

  • A New Era for Mechanical CAD Time to Move Forward from Decades-Old Design JESSIE FRAZELLE
    TEXT COMMIT TO 1 OF 12 memory ONLY A New Era for Mechanical CAD Time to move forward from decades-old design JESSIE FRAZELLE omputer-aided design (CAD) has been around since the 1950s. The first graphical CAD program, called Sketchpad, came out of MIT [designworldonline. com]. Since then, CAD has become essential to designing and manufacturing hardware Cproducts. Today, there are multiple types of CAD. This column focuses on mechanical CAD, used for mechanical engineering. Digging into the history of computer graphics reveals some interesting connections between the most ambitious and notorious engineers. Ivan Sutherland, who won the Turing Award for Sketchpad in 1988, had Edwin Catmull as a student. Catmull and Pat Hanrahan won the Turing award for their contributions to computer graphics in 2019. This included their work at Pixar building RenderMan [pixar. com], which was licensed to other filmmakers. This led to innovations in hardware, software, and GPUs. Without these innovators, there would be no mechanical CAD, nor would animated films be as sophisticated as they are today. There wouldn’t even be GPUs. Modeling geometries has evolved greatly over time. Solids were first modeled as wireframes by representing the object by its edges, line curves, and vertices. This evolved into surface representation using faces, surfaces, edges, and vertices. Surface representation is valuable in robot path planning as well. Wireframe and surface acmqueue |march-april 2021 5 COMMIT TO 2 OF 12 memory I representation contains only geometrical data. Today, modeling includes topological information to describe how the object is bounded and connected, and to describe its neighborhood.

  • Parametric Design Thinking About Digital and Material Surface Patterns
    INTERNATIONAL CONFERENCE ON ENGINEERING AND PRODUCT DESIGN EDUCATION 6 & 7 SEPTEMBER 2018, DYSON SCHOOL OF DESIGN ENGINEERING, IMPERIAL COLLEGE, LONDON, UNITED KINGDOM PARAMETRIC DESIGN THINKING ABOUT DIGITAL AND MATERIAL SURFACE PATTERNS Wenche LYCHE, Arild BERG and Kristin ANDREASSEN OsloMet – Oslo Metropolitan University ABSTRACT There is a growing need in contemporary society to understand new and emerging relationships between technology and creativity. In practice-oriented areas of education such as design, many instructors have come to understand the importance of different learning styles and how students benefit when presentation of new material is varied to reach all students. The concept of parametric design thinking enabled by advanced computational processes has recently been identified as a relevant approach to design education. The present research further explores parametric design thinking through two case studies of design workshops in an educational context and how this approach can promote diversity. The first case (Robotised Clay Workshop) documents material exploration and creative and aesthetic possibilities in digitalised clay processes. The second case (Surface Patterns in Textiles: From Tradition to Digitalisation and Back) explores digitalised processes in hybrid textile design. The two case studies contribute to the exploration of parametric design thinking as an educational approach and discuss digitalisation and the relations of body, hand and mind in terms of the Vygotskyan ‘zone of proximal development’. This content was synthesised for a workshop on surface patterns for third-year bachelor design students. The paper identifies some potentials and pitfalls of this pedagogical approach and concludes that students’ awareness of conformity and diversity in the design process can be used as a starting point to explore digital surface patterns, offering students a new way of learning about function, aesthetics and product semantics through parametric design thinking.
