Question
it) is the point (-1, -2, 3) visible from the point (1.2, 0) if there is an opaque ball of radius 1 centered at the origin?
yes
Suppose that you stand at the point (1, 2.0) and look in the direction of a point that is not visible because it is behind the ball. You will then be looking at a point on the sphere.
if(-1.-2.3) is not visible from (1.2.0), find the point on the sphere at which you are looking if you look in the direction of (-1.-2,3) Otherwise, find the point on the sphere at which you look if you are
looking in the direction of (-1,-2.2)
Point (X. y. 2) = (0.3.3)
