(5 marks) Consider the graphics pipeline we have discussed in class. We understand that there are three operations in the pipeline: namely transformation, clipping, and projection, in that order. Assume that each such operation takes 10 time units. For a graphics application, suppose that it contains 5 separate vertices. Answer the following questions. (a) If we apply sequentially the three operations in that order) to each vertex and process all the 5 vertices one after another, calculate how many time units we need to process them. Show your work. (b) Suppose that a graphic card implements the pipeline and needs 10 time units to conduct each operation. If we apply the pipeline in the card to process all the 5 vertices, calculate how many time units the card needs to process them. Show your work
