Suppose the points (1, 0, 0), (1, 1, 1), and (1, 0, 2) are the vertices of a planar patch and the vertices are listed in a counter-clockwise order as seen from outside the object. In each case that...

are the vertices of a planar patch and the

vertices are listed in a counter-clockwise order

as seen from outside the object. In each case

that follows, indicate whether a ray of light

originating at the given point would strike the

surface of the patch from outside or inside the

object.

a. (0, 0, 0)

b. (2, 0, 0)

c. (2, 1, 1)

d. (3, 2, 1)
