Hy,
I have a question, if the matrices multiply like this:

(rot z * tran z * rot x * tran x) I get one of these
T =
0.4182 0.8711 -0.2575 1.1692
-0.4756 -0.0316 -0.8791 0.1847
-0.7739 0.4901 0.4011 5.2261
0 0 0 1.0000
From this T what is the x, y, z?
Is correct like this: ?!?
T =
x1 x2 x3 kx
y1 y2 y3 ky
z1 z2 z3 kz
x1.T(1) ; x2.T(5) ; x3.T(9)
y1.T(2) ; y2.T(6) ; y3.T(10)
z1.T(3) ; z2.T(7) ; z3.T(11)
kx.T(13) ; ky.T(14); kz.T(15)
and if I want to join them to plot it (drawn it) the arms(links) then so will I need do this way:?
link1: x1->x2 y1->y2 z1->z2
link2: x2->x3 y2->y3 z2->z3
link3: x3->kx y3->ky z3->kz ?!?
