Consider an image containing a set of 5,000 1-inch unconnected vectors.

a) Contrast the storage required for a vector display list with that for a 1-bit raster image for a 1024 by 1024 bilevel (monochrome) display to store this image. Assume that it takes an 8-bit "op-code" to specify "vector-draw" and four 10-bit coordinates (i.e. 6 bytes) to store a vector in the vector display.

b) How do these numbers vary as a function of the number and size of the vectors, the number of bits per pixel, and the resolution of the raster display?

c) What conclusion(s) can you draw about the required relative sizes of refresh memory?
