ARCH 481 3D Modeling and Rendering Time: Tu/Th, 10:30 to 11:50 Room:Gould 236 Instructor: Nan-Ching Tai

Introduction This course is about beginnings, about preparation for the use of 3D computing for the architectural profession. It is a fast-paced, “learning by doing” lecture and laboratory course. Throughout the course you will be introduced to a number of software packages you'll possibly encounter in architectural practice.

Introduction 3D Modeling & Rendering: Form Z Presentation: Adobe PhotoShop, Adobe Illustrator Web Presentation (optional) Dreamweaver, Flash Video Presentation (final project) Adobe Premiere, iMovie

Goal of the Course 3D Modeling & Rendering: Weekly lectures and exercises will guide you through the steps of developing a 3D model of your architectural project in formZ, culminating in the creation of an animated walkthrough for the final exercise. Digital media : To develop your understanding of Computing Graphic programs and ability of using digital media in the design process and presentation.

Goal of the Course Examples:

Course Format Lecture: Weekly lectures cover a different cluster of topics, building from the simple to more complex, providing conceptual information you need. Weekly Exercise : 9 weekly exercises are very important elements of the course. They provide the opportunities to test comprehension and demonstrate skill. In-Class exercise: Simple in-class exercise provides basic foundation for your weekly exercise

Course Format Demonstration : Church of Light Tips and Tricks

Tuesday/LectureThursday/Lab section Power Point LectureDemonstration (topics, tips, tricks, common question etc) Demonstration (Light of Church) Help Hours for individual project In-Class exercise Course Format

Week 5 Tu 4/27 IRREGULAR SHAPE Thur 4/29 Power Point Lecture Landform modeling: contours, meshes and stepped model. GIS (demonstrate download GIS contour information for site model) Demonstration site model for church of light, adding tree Help Hours for individual project In-Class exercise Course Format Example

Schedule Weekly schedule: (available on course webpage) Tuesdays: lecture Thursdays: lab exercise due the following Friday (1) renderings of progress on model (2) Formz model

Grading grading: 9 exercises 0.6 points possible for each exercise your grade is the sum of the points you receive for the exercises extra credit assignments are worth an additional 0.1 point Take-home final (optional) available in the end of quarter

Grading Grading criteria Exercise grades are based on technical correctness and understanding of specific issues. Your exercise will generally be given a score between 0.3 and 0.6, with 0.4 to 0.5 being average Late assignment will decline 0.1 for each week that it is late

Assignment Proposed project for Thursday Bring basic information of the project you want to work on in next class. Plans, Sections and at least one 3D images. detailed enough to be interesting not too large to detail dimensioned drawings completed design (no current studio projects) Good project to model:

Assignment Previous Studio project, historical building, contemporary masterpiece Reason: Light? Form? Structure? Detail

computer assisted 3d modeling

digital representation of drawings: –raster –vector

raster drawing: –pixelated –contains no other control information –component pixels can be edited, but not whole object

vector drawing: –represented as pixels on screen –defined by control information –object can be scaled, rotated and otherwise edited

2d vector data types: polylinecirclebezier curve

3d vector data types: faceted analytic primitive NURBS

polygon vs. solid model: polygonsolid

boolean operations: uniondifferenceintersection

holes:

manipulating 3d models in a 2d space: –plane projection –the pointing problem

objects in workspace projected onto 2d screen:

mouse only moves in 2d –defines a line in 3d space –more information needed to select one point
