1.
Ist die Gondel eine Kugel. Dann könnte es wie folgt gerechnet werden.
Y = [10, 21, 13.5] + 8/ABS([1, 0, 1])·[1, 0, 1] = [4·√2 + 10, 21, 4·√2 + 27/2] = [15.66, 21, 19.16]
Y = [10, 21, 13.5] - 8/ABS([1, 0, 1])·[1, 0, 1] = [10 - 4·√2, 21, 27/2 - 4·√2] = [4.34, 21, 7.84]
2.
[6, 5] + t·[1, 4] = [61, 81] + s·[-2, -2] --> s = 24 ∧ t = 7
U = [6, 5, 12] + 7·[1, 4, 1] = [13, 33, 19]
V = [61, 81, 0] + 24·[-2, -2, 1] = [13, 33, 24]
