3.2. Royalty-free images are purchased and then used without paying addition license fees
3.3. Right-managed images require you negotiate with the right holder regarding terms
4. Vector-drawn graphics
4.1. Applications of vector-drawn object
5. Vector-drawn images are used in areas:
5.1. Computer-aided design programs needed by architects and engineers
5.2. Graphic artists designing for print media
5.3. 3-D animation programs
5.4. Applications requiring drawing of graphic Shapes
6. Vector-drawn images vs bitmaps
6.1. Vector objects are easily scalable without loss of resolution or image quality
6.2. vector images cannot be used for photorealistic images
6.3. Bitmaps are not easily scalable and resizable
6.4. Bitmaps can be converted to vector images using autotracing
7. Features of 3D application
7.1. Modeling
7.2. Extrusion
