Question 1
|
In Cyrus-Beck algorithm for line clipping the value of t parameter is computed by the relation :
(Here P1 and P2 are the two end points of the line, f is a point on the boundary, n1 is inner normal)
|
(P1 – fi) × ni / (P2 – P1) × ni
|
|
|
(fi – P1) × ni / (P2 – P1) × ni
|
|
|
(P2 – fi) × ni / (P1 – P2) × ni
|
|
|
(fi – P2) × ni / (P1 – P2) × ni
|
Correct Answer: B
