Which of the following line algorithms best balances the processing load among all the processers?
Parallel line algorithm
DDA line algorithm
Both a. and b. balances the load equally
None of the above
Correct Answer :
A. Parallel line algorithm
If a parallel line algorithm has 'n' processes then this algorithm divides it into a number of partitions and generates line segments. Thus the load on the processors gets divided.
