2.1.2.1. I. Modeling

2.1.2.2. II. Extrusion

2.1.2.3. III. Lathing

2.2. Rendering

2.2.1. a. Use of intricate algorithms to apply user-specified effects

2.2.2. b. Takes many hours for a single images

3. Color Palettes in Multimedia

5. Types of Graphic

5.1. Bitmap (raster) graphics

5.1.1. a. Bitmaps are an image format suited for creation of:

5.1.1.1. I. Photo-realistic images

5.1.1.2. II. Complex drawings requiring fine detail

5.1.2. b. Where do bitmaps come from?

5.1.2.1. I. Capture a bitmap using a camera

5.1.2.2. II. Capture a bitmap from a photo or other artwork using a scanner to digitize the image

5.1.2.3. III. Make a bitmap from scratch with a paint or drawing program

5.1.3. c. The industry-standard programs for bitmap painting and editing are:

5.1.3.1. I. Adobe's Photoshop and Illistrator

5.1.3.2. II. Corel's Painter and CorelDraw

5.1.4. d. Advantages and Disavtanges

5.1.4.1. I. Advantages

5.2.3. c. Vector-drawn images versus bitmaps

5.2.4. d. Advantages and Disadvantages

5.2.4.1. a. Advantages

5.2.4.1.1. I. Vector Images use less memory spaces

5.2.4.1.2. II. Vector Objects are easily scalable without loss of resolution or image quality

5.2.4.2. b. Disadvantage

5.2.4.2.1. I. Objects/drawings cannot have texture

5.2.4.2.2. II. Cannot be used for photorealistic images
