a) Digital images can be created as either raster or vector images. Both type of images have its own distinctive characteristics that separate raster and vector images. 1. Identify the characteristics of a raster image. (4 marks) Identify the cause for image degradation on raster images. (4 marks) Identify the characteristics of vector image. (4 marks) b) - Projection plane Figure 2: Simple projection of a virtual camera Figure 2 shows a simple projection of a virtual camera. Explain the TWO (2) steps we can use if we want to visualize an object as 'moving (4 marks) c) Explain the THREE (3) types of surface light reaction when an object is shone by a white light. Describe the importance of material surface characteristics in determining the type of light reaction. (9 marks) a) Digital images can be created as either raster or vector images.
