Review – a brief CAD history

The design is a drawing of the product e.g. Geometric drafting in 2D

The design is a surface model of the product e.g. Geometric surface modeling in 3D

The design is a 3D model of the product e.g. Solid modeling

The design is an editable 3D model of the product e.g. Parametric modeling

The design is the integrated representation of

all the compositional, analytical and fabrication

representations of the product

(Geometry is just one part of the model) e.g. Product Data Modeling, BIM (Building Information Modeling)

Basic Theory in Digital Design

Geometry for making 3d objects

Modeling 3d object: controlling 2d/3d components

Creating an object (hard to do, except making primitives)

And Modifying it (very hard to do – modify in 2d geometry)

Creating 3d objects0 Primitives

To make primitive objects, and modify them

Creating 3d objects1 Extrusion: extruding a polygon

Creating 3d objects2 Lathing: revolving a surface

Creating 3d objects3 Sweeping: sweep a section profile

onto a polygon path

Creating 3d objects4 Others: Skinning, Boolean operation (CSG)…

From 2d geometry to 3d model: Lathe

2d drawing 2d modifying Lathe (revolving) to 3d

Boolean Operation in 2D Geometry

B − A

A ∪ B

A ∩ B

SketchUP – a surface 3d modeling tool

(3ds Max as well)

SketchUP models are surface-based models

SketchUP model is Surface 3d, NOT Solid 3d

From the book SketchUP for dummies

Edge & Face made a sketchUP model

Edge (Line) & Face (Surface) Surface-based 3d model

From the book SketchUP for dummies

All lines are actually “straight”

A curve is a collection of

straight lines.

Any organic-shaped curves

are still straight lines.

From the book SketchUP for dummies

All surfaces are actually “flat”

A surface (face) is a

collection of edges (lines),

at least three edges.

Any organic-shaped

surfaces are still a

collection of flat surfaces.

From the book SketchUP for dummies

Rendered by V-Ray plugin, on SketchUP

3d Warehouse: download/upload your SketchUP models!

Vray renderer – Same to MR, but different interface

Rendering basics – all about lights

Lighting Source

- Direct Illumination (e.g. Sunlight)

- Indirect Illumination

- Environment

Target Objects

- Diffuse

- Intensity

- Texture Map

- Shadow casting

- Ambient Occlusion …

- Reflection

- Refraction

- Caustics

Camera

- Source, Target

- Field of View

Rendering Overview

Diffuse

Color

Texture Map

Transparency: White Transparent, Black Opaque

BRDF: bidirectional reflectance distribution function

For Transparent Bitmap BG

Reflection

Reflection color: White Transparent, Black Opaque

Reflection Glossiness

Refraction

IOR: Index of Refraction

Emissive

Photo-realistic Rendering: Global illumination, Ray tracing…

To “compute” the interactions between light rays and all target objects in the

given environment

“Rendering” usually refers to the “control” such interactions with amount of

options

Next week: Digital Design & Fabrication (3d Printing)

Example

Design your building & skin

- building mass could be a simple shape

- building skin design alternatives (3 or more)

- use various patterns and your curtain families

Building “Information” modeling

Vasari & Design Analysis: Wind rose & wind tunnel

Wind rose shows you the average of yearly wind speed of your site location (weather data)

Wind tunnel analysis for both building exterior and interior

Any geometric model can be loaded into Vasari (Revit) for further use

- the F-22 raptor flight model downloaded from Google 3d warehouse

(SketchUP *.skp file)

Revit (Vasari) can

import SketchUP files

Video-based Design Presentation

http://www.youtube.com/watch?v=ZJnPMHe27MM

Video-based Design Presentation (so-called Multi-Media)

Easy to follow.

As a picture is worth a thousand

words so even if a certain idea is

unclear orally; it can be clearly stated

via pictures and diagrams.

Video is a sequence of images.

Background music, clear texts, title,

description text, voice recording, and

so on will help your design

representation.

Example Videos: Final Presentation Videos

Example Videos

Intro, Title text…

Concept description…

Your (3D) Design Representation (animation clip)

Ending credit…

Example Videos: Animation Clips (today’s subject) using 3d Graphics Tools: JPG sequence

Video File Formats

How to make an animation clip for design representation?

Theoretical Background for movie-making

SketchUP, Vray (3ds Max Design, Mental Ray, etc.)

SketchUP Scene-based animation: Movie file & JPG sequence

SketchUP + Vray render JPG sequence

Adobe Photoshop, After Effects, Daum PotEncoder, etc.

JPG Sequence a movie clip file (.mov)

Encoding them and converting into various movie formats (e.g. .mp4)

Power Director (Adobe Premiere, etc.)

Planning Your Movie-based Design Presentation

Edit your movie and export (encoding)

File formats and Codec for audio/video

From Edison’s Phonograph To digital files such as MP3, MP4, AVI…

- Nowadays all audio/video formats are digital

Uncompressed files are too big to handle: e.g. WAV, BMP, AVI (uncompressed)…

Most digital file formats are compressed formats, in different ways/standards

Compressed files: e.g. MP3, JPG, MP4, AVI (compressed), MPG…

Compressor / Decompressor Codec (for digital audio/video)

Codec plays an important role to store your audio/video/pictures etc. files into the computers, and to

play those files from the computers.

Internet (Web) Streaming file formats

streaming lets you to play audio/video while downloading: ra, wmv, wma, flv, swf…

Compression: Audio file examplehttp://www.crutchfield.com/S-N8m68AJP58L/learn/learningcenter/home/fileformats.html

Video File basics

Video

Screen size: pixels

- DVD (720X480pixel), HD (1280X720), Full HD (1920X1080)…

FPS: frame per second

- 25fps, 30fps, 10fps…

Bit rate: bit per second

- (K)BPS

Codec (file type) – Compression rate

- AVI, WMV, MP4, FLV, SWF…

Audio

Channel: 2Ch (Stereo), 5.1Ch (Dolby surround..)

Bit rate: 128kbps

Codec (file type): MP3, WAV, OGG…

Others

Caption, video effect, water mark…

Authoring a Video

Converting video file formats

Convert Audio file format using Pot Encoder:

1. Open a given mp3 file (3.3MB) OR open your any MP3 file

2. Convert it to smaller than 1MB

3. Save it as another MP3 file

Convert Video file format using Pot Encoder:

1. Open an mp4 video file (9.25MB) OR open your any movie file (short)

(Search YouTube video and download it using voobys.com, etc.)

2. Convert it to a smaller size file

3. Save it as *.AVI or *.WMV, or other file format (not original MP4)

4. Extract the audio from the video file – Save it as *.MP3 file (128kbps)

Save total 3 files: 1 movie file and 2 MP3 files under your named folder

Daum Pot Encoder – e.g. Encoding & simple editing

Camtasia Studio – e.g. Capturing screen movie clips

Adobe After Effects – e.g. Making movie clip using JPG sequence

Adobe Premiere – e.g. Making movie clip slower (more frames)

Flash – e.g. Web-supported movies & exe files

Power Director – e.g. Making your final video project

Import your libraries – e.g. Movie clips, Sound, Music, Images, Text call

outs…

Place your components on the TimeLine – Editing final video

Adding Transition, Text call outs, music, control music volume, etc.

Saving your final project file: *.PDS file

Exporting a final video file: e.g. MP4, AVI…
