By applying the Cohen-Sutherland clipping algorithm, what would be the computed code for the P1 point?

*Consider the following order for processing the edges of the clipping window: left-down-right-up

Consider applying the Cohen-Sutherland line clipping algorithm for the line P0P1. Which of the following points will be identified by applying the algorithm? The algorithm implements the following order of traversing the edges of the clipping window: up-down-right-left.

How is the vector normalization operation computed?

Which of the following code sequences represent a correct implementation of the plus equal operator having the header below?

Consider a triangle defined by vertices P0, P1 and P2. n_triangle represents the normal vector to the plane determined by the triangle. Which of the following variants represents a correct method for computing the vector n_P2P0 (vector perpendicular to the edge P2P1, oriented as in the drawing, does not matter the length of the vector)?
