Consider a ray with direction vector de R" being reflected from a mirroring surface resulting in reflection vectorr. At the point of intersection, the surface has the normal vector n. See Figure 1 for the setup. (a) Given d and r, determine the normal vector n, of the surface at the point of reflection! (2P) (b) Given d and n, determine the direction vector r for the reflection of the ray! (3P)
