15. (T/F) If S = {v.....v} is an affinely independent set in
R" and if p in R" has a negative barycentric coordinate
determincd by S, then p is not in aff S.
16. (T/F) When color information is specificd at cach vertex
V1, V2. V3 of a triangle in R', then the color may be inter-
polated at a point p in aff {v, V2, V3} using the barycentric
coordinates of p.
17. (T/F) If VỊ, V2, V3. a, and b are in R3 and if a ray a +ib for
120 intersects the triangle with vertices v. V2, and v3, then
the barycentric coordinates of the interscction point arc all
nonnegative.
