1. Consider three different raster system with resolutions of 640 by 480,1280 by 1024, and 2560 by 2048. What size frame buffer (in bytes) is needed for each of these system to store 12 bits per pixel? How much storage is required for each system if 24 bits per pixel are to be stored?

2. Suppose an Red, Green, Blue raster system is to be designed using an 8 inch by 10 inch screen with a resolution of 100 pixels per inch in each direction. If we want to store 6 bits per pixel in the frame buffer, how much storage (in bytes ) do we need for the frame buffer?

3. Explain how virtual-reality systems can be used in design applications. What are some other applications for virtual- reality system?
