1. Vector-drawn images versus bitmaps -Vector images use less memory space and have a smaller file compared to bitmaps -Vector object are easily scalable without loss of resolution or images quality -Resizing a bitmapped image requires either duplicating pixels, while vector image, a rescaled image retains the quality of the original -cannot be used for photo realistic images -it cannot have texture, it can only have paint colours
2. 3-D drawing and rendering -tools include-Daz3D, Form*Z, NewTeck's Lightwave, Autodesk's Maya -Modeling-Placing all the elements into 3-D space -Lathing - a profile of the shape is rotated around a defined axis
3. Colors and Palettes in Multimedia -Understanding natural light and color *Additive color, Subtractive color, -Color paletters *Dithering
4. Images file types used -Macintosh formats, Windows formats, Cross-platform formats, -Image file compression
5. Images re generated into - -Bitmaps *is a simple matrix of the tiny dots that form an image and are displayed on a screen or printed *are an images format suited for creation of -Photo realistic images and Complex drawings requiring detail *bitmap come form a camera , artwork or photo, scratch with a paint or drawing program. * Legal rights protecting use of images from clip are galleries fall into three basic group- Public domain images, Royalty-free images and Right-managed images *Capturing and editing images directly form the screen
6. Images re generated into- -Vector-drawn graphics *Application of vector drawn object *How vector-drawn images work *Vector-drawn images versus bitmaps *used in CAD programs needed by architects and engineers * Vector-drawn images work is a line that is described by the location of its two endpoints. *Vector drawing make use of Cartesian coordinates
