by 宇豪 康
1. Vector-drawn images are use in the following areas
1.1. Computer-aided design (CAD) programs needed by architects and engineers
1.2. Graphic artists designing for the print media.
1.3. Applications requiring drawing of graphic shapes.
2. Vector-drawn graphics
2.1. Applications of vector-drawn object
2.2. How vector-drawn images work
2.3. Vector-drawn images versus bitmaps
3. Vector Graphics
3.1. Advantages
3.1.1. Vector images use less memory space.
3.1.2. Vector objects are easily scalable without loss of resolution or image quality.
3.1.3. Easy to edit the drawings as each object is independent of the other.
3.2. Disadvantages
3.2.1. objects/drawings cannot have texture
3.2.2. cannot be used for photorealistic images.
4. 3-D animation, drawing, and rendering tools include
4.1. Daz3D
4.2. Form*Z
4.3. NewTek's Lightwave
4.4. Autodesk's Maya
4.5. Trimble's SketchUP
5. PNG
5.1. Supports more than 16.7 million colors.
5.2. use Lossless Compression Technique
5.3. Image can have transparent portion
5.4. No animation
6. Making still Images
6.1. still images are generated in two way
6.1.1. Bitmaps
6.1.2. Vector-drawn graphics
6.2. Bitmaps editors are called painting program and vector editors are called drawing program.
7. Type of Graphic
7.1. Bitmap graphics
7.2. Vector graphics
8. Bitmaps Graphics
8.1. Advantages
8.1.1. can have different textures on the drawing, detailed and comprehensive
8.2. Disadvantages
8.2.1. Large file size
8.2.2. Not easy to make modification to objects/drawings
8.2.3. Graphics become "blocky" when the size is increased
