What are object oriented drawings?
What do CAM, CAD, and CIM stand for?
*CAD - Computer Aided Design
*CAM - Computer-Aided Manufacturing
*CIM - Computer- Integrated Manufacturing
How to create a powerful presentation?
-Remember your goal
-Remember your audience
-Outline your ideas
-Be stingy with your words
-Keep it simple
-Use a consistent design
-Be smart with art
-Keep each slide focused
-Tell them what you're going to tell them, then tell them, then tell them what you told them.
What is a video digitizer?
A video digitizer is a software that takes an analog video still frame and converts it to a digital still image.
Whats the benefit of non-linear drawing?
Better quality
What is the difference between drawing and painting modules?
Painting modules create bitmapped graphics whilst drawing modules create vector graphics
Advantages of computer graphics are
-Better for creating printed graphs, charts, and illustrations
-Lines are cleaner and shapes are smoother
Some Integrated programs contain both drawing and painting
-Allows you to choose the right tool for each job
Some programs merge features of both in a single application
-Blurs the distinction between types
-Offers new possibilities for a amateur and professional illustrators
Computer Aided Design (CAD) Software
-Allows engineers, designers, and architects to create designs on screen for products ranging from computer chips to public buildings
-Can test product prototypes
-Cheaper, faster, and more accurate than traditional design-by-hand techniques
Computer-Aided Manufacturing (CAM) is the process by which data related the product design are fed into a program that controls to manufacturing of parts.
Computer-Integrated Manufacturing (CIM) refers to the combination of CAD/CAM and is a major step toward a fully automated factory.
Presentation Graphics: Bringing Lectures to life
-Automates the creation of visual aids for lectures, training sessions, sales demonstrations, and other presentations.
-Creates slide shows directly on computer monitors or LCD projectors, including still images, animation, and video clips.
Modern media contains dynamic information, which is information that changes over tiem or in response to user input.
- Animation
- Desktop Video
- Audio
- Hypertext and Hypermedia
Animation: Graphics in Time
- Each frame of computer-based animation is a computer-drawn picture, the computer displays these frames in rapid succession
- Tweening: Instead of drawing each frame by hand, the animator can create key frames and objects and use software to help fill in the gaps
Analog and Digital Video
-A video digitizer can convert analog video signals from a television broadcast or videotape into digital data
Dynamic Media: Beyond the Printed Page
-Many video digitizer can import signals from televisions, videotapes, video cameras, and other sources.
-Digital video cameras capture footage in digital form
-Digital videos can be copied, edited, stored, and played back without any loss of quality
- Digital video will soon replace analog video for most applications.
Video Production goes digital
-Today most video editing is done using nonlinear editing technology.
-Video editing software, such as Adobe Premiere, makes it easy to eliminate extraneous footage, combine clips from multiple takes, splice together scenes, create specific effects and perform a variety of other activities
-Morphs are video clips in which one image metamorphoses into another
-Data compression software and hardware are used to squeeze data out of movies so that they can be stored in smaller spaces.
The synthetic Musician: Computers and Audio
-Audio digitizer - captures sound and stores it as a data file
-Synthesizer - an electric instrument that symbolizes sounds using mathematical formulas
-MIDI (Musical Instrument Digital Interface) - Standard interface that allows electronic instruments and computers to communicate with each other
Dynamic Media: Beyond the Printed Page
- Music is digitized on audio CDs at a high sampling rate and bit depth - high enough that its hard to tell the difference between the original analog sound and the final digital recording.
Samplers, Synthesizers, and Sequences: Digital Audio and MIDI
- Multimedia computers can control a variety of electronic musical instruments and sound sources using MIDI
- MIDI commands can be interpreted by a variety of:
*Music Synthesizers
*Samplers
-A piano-style keyboard sends MIDI signals to the computer
* Computer interprets the MIDI commands using sequencing software
- Sequencing software turns a computer into a musical composing, recording, and editing machine
- Electronica - Music designed from the ground up with digital technology.
* Some of the most interesting sequence music
Hypertext refers to information linked in non-sequential ways.
Hypermedia combines text, numbers, graphics, animation, sound effects, and other media in hyper-linked documents.
- Useful for on-line help files
- Lets the user jump between documents all over the Internet
Hypermedia documents can be disorienting and leave the reader wondering what they've missed.
- Documents don't always have the links readers want.
- Authors can't build every possible connection into documents.
- Some readers get frustrated because they can't easily get "here" from "there"
Virtual reality combines virtual worlds with networking
- It places multiple participants in a virtual space
- People see representations of each other, sometimes called avatars
- Most avatars today are cartoonish, but they covey a sense of presence and emotion
Tele-Immersion
- Uses multiple cameras and high-speed networks to create a videoconferencing environment in which multiple remote useres can interact with each other and with computer-generated objects
- Combines the display and interaction techniques of virtual reality with new vision technologies that allow participants to move around in shared virtual spoaces, all the while maintaing their unique points of view.
Augmented Reality (AR):
-The use of computer displays that add virtual information to a person's sensory perceptions.
