Computer Art Introduction


This class will provide you with a good overview of the types of art and their applications created on a computer. This is an introductory class of approximately 30 minutes and will be provided at no cost.


What programs to use; free or commercial, and why

  • Free is a great price getting started

  • Some free programs are full featured, some have saves disabled

  • Don't buy until you are sure you want to pursue doing art or graphics work

  • Studios and professional users pay $3,000+ for a single program

  • My art is created with programs collectively costing less than $1,000

  • Beginners could try Bryce (free) to get a feel for 3D

  • Eon-software provides a free version of Vue which is more advanced than Bryce and more complicated. Versions of Vue range in price from $100-$1,000

  • Google Sketchup is a free program that can be used to create 3D models of moderate complexity

  • Models of people provides greater expressive depth

    • DAZ Studio (free) can be used for people models (integrated with Bryce)

    • Poser is a semi-professional people/animal modeling tool $300+

  • Zbrush is a 3D modeling program $500+


2D or 3D, what's the difference?

  • 3D takes care of the light and shadows

  • 2D lets you choose what to paint and how

  • 3D uses models that you can place into a scene

  • 2D uses brushes that can place objects unto layers for a pseudo 3D effect

  • 3D scenes have to be rendered to be viewed sometimes taking many hours

  • 2D is more of what you see is what you get

  • 3D can produce much more detail

  • 2D is what a rendered 3D scene becomes

  • 2D is used for most advertising in papers, magazines, and the web

  • 2D is more like painting and drawing

  • 3D is more like sculpting and pottery

  • 3D is more difficult to learn

  • 2D has many more plugins and is more widely used

  • Resolution matters in 2D (paint programs)

  • Resolution in 3D is more about rendering than modeling

  • Polygons matter in 3D

  • 2D Programs

    • Vector programs are resolution independent

      • Small file sizes

      • Print to various sizes without resolution loss

    • Bit Mapped programs resolution is based on the canvass size

      • Large file sizes for printing

      • Will not scale up without resolution/clarity loss

Digital photography, scanners, printers, and image manipulation

  • In our 3D world most everything is presented (imaged) in 2D

  • Digital images are everywhere now

  • Scanners are just printers reading an image

  • Cropping, adjusting and scaling 2D images are techniques used to improve the image

  • Upscaling an image will cause a loose of resolution and clarity

  • Image manipulation can be art


Why is everything so complicated?

  • Choices add complexity

  • Increases in sophistication generate complexity

  • Basic principles are often embodied into the programs

  • Once you learn a tool, other similar tools are easier to learn

  • Attempts to simplify often result in programs with few choices

  • A menu with one choice isn't very desirable unless it it all you ever want


What type of graphics/art can I add to my web pages or send in email?

  • There are several standard formats that can be viewed by most everyone

  • jpeg, gif, flash, and png are the most common

  • jpeg is most common and all digital cameras create a jpeg image

  • Simple animations are possible using gif format

  • jpeg and gif are lossy compressed format

  • The png format can be lossless and maybe the best format for sharing printable content

  • There are some 3D formats but most require a separate viewer

  • Flash is supported by most browsers

An overview of Copyright Laws and Fair Use

  • Any original content once published is copyrighted by the owner of the content

  • You do not need to apply for a copyright unless you feel the item will likely be copied

  • Copyrighted content may not be used without the permission of the owner

    • Except for Fair Use

      • Satire, commentary, 'credited' and scholarly uses

  • Years ago it was thought that you could use a portion of an image/book without concern

    • Other than Fair Use, modifying any portion is considered a derivative work (copyrighted)

    • Creative Commons provides a copyright method that can be set for various restrictions

    • Open Source and GPL copyright licensing is less restrictive than standard copyright but with restrictions

  • If in doubt, then assume that copyright laws apply

  • US copyright laws are not internationally upheld
