1. 3-D drawing

1.1. Modeling-Placing all the elements into 3-D space

1.2. Extrusion-The shape of a plane surface extends some distance

1.3. Lathing-A profile of the shape is rotated around a defined axis

2. Color and Palettes

2.1. Additive color

2.1.1. Color is created by combining colored light sources in three primary colors- red, green, blue (RGB)

2.2. Subtractive color

2.2.1. Color created by combining colored media such as paints or ink. Primary color: cyan, magenta and yellow (CMY)

2.3. Color palettes

2.3.1. Palettes are mathematical tables define the color of pixels displayed on the screen

2.4. Dithering

2.4.1. A process whereby the color value of each pixel is changed to the closest matching color value in the target palette

3. Image file type

3.1. Macintosh formats

3.2. Windows formats

3.3. Cross-platform formats

4. Bitmaps editors are called painting program

4.1. A bitmaps is a simple matrix of the tiny dots that form an image and are display on a screen or printed

4.2. It used combination block of pixels to represent an image

4.3. Each pixel assign a specific location and color

4.4. Capture a bitmap using a camera, from a photo or other artwork using scanner to digitize the image.

4.5. Legal rights protecting use of image

4.5.1. Public domain images

4.5.2. Royalty-free images

4.5.3. Right-managed images

4.6. Industry-standard programs

4.6.1. Adobe's photoshop and Illustrator

5. Vector editors are called drawing program

5.1. Computer-aided design (CAD) programs needed by architects and engineers

5.2. Graphic artists designing for the print media

5.3. 3-D animation programs -changes of position, rotation, and shading of light

5.4. Application requiring drawing of graphic shapes

6. Still images are generated in two ways -Bitmaps -Vector-drawn graphics
