13drehmatrix:
14
151 0 0 also in x-richtung wird gedreht mit phi=90 in 0 1 0
16
17matrix:
18 0 0 0 1 0
19 1 0 0 0 = 1
20 0 0 0 0 0
21
22also
23 cos-p 0 0
24 sin-p 0 0
25 0 0 0
26
270 1 0 also y-richtung wird weiter gedreht in -1 0 0
28
29 0 -1 0
30 0 0 0
31 0 0 0
32
33also:
34 cos-p -sin-p 0 0 -1 0
35 sin-p cos-p 0 --> 1 0 0
36 0 0 0 0 0 0
37
38damit wird gedreht: 1 0 0 -> 0 1 0 -> -1 0 0 -> 0 -1 0 -> 1 0 0
39
40nun mit theta = 90 damit wird 0 0 1 zu 1 0 0
41
42also:
43 0 0 1
44 0 0 0
45 0 0 0
46
47weiter 1 0 0 --> 0 0 -1
48
49also:
50 0 0 1
51 0 0 0
52-1 0 0
53
54und damit klappt auch 0 0 -1 auf -1 0 0 und weiter auf 0 0 1
55
56das waere jetzt also
57 cos-p cos-t -sin-p sin-t
58 sin-p cos-p ?
59 -sin-t ? cos-t
60
61
62wenn theta = 90 muss auch mit dem einheitsvector in y das richtig passieren
63nämlich
640 1 0 --> 0 0 -1 -->
