<div><br>
</div>
<div>So I send a mail some time ago to the list and got no answer,
so I guess it was not really clear.</div>
<div><br>
</div>
<div>I come now with a more simple version of my problem.</div>
<div><br>
</div>
<div>
I have two cubes,</div>
<div><br>
</div>
<div>cube A</div>
<div>translationXYZ 0 0 0</div>
<div>rotationXYZ 0 0 0</div>
<div><br>
</div>
<div>and cube B</div>
<div>translationXYZ 12 5 6</div>
<div>rotationXYZ 0 0 0</div>
<div><br>
</div>
<div>now I want to calculate with only thoses informations, the
rotations in X Y and Z for cube A to look at cube B. (numbers
are irrelevent, I want to make the algorythme)</div>
<div><br>
</div>
<div>I have tryed many things, with trigonometry, learned about
Gimbal lock, read everything I could about euler angles, etc ...
result is it's not working right.</div>
<div><br>
</div>
<div>I attached an exemple patch. The math inside are based on the
help I got on a math forum. It quite look like the thing I was
trying to do but it doesn"t work better :)</div>
<div><br>
</div>
<div>Anybody ? Any idea?</div>
<div><br>
</div>
<div>cheers</div>
<div><br>
</div>
<div>PS : I try to do that to calculate joint orientations of
kinect skeleton. and even though there might be other
solutions(wich I be glad to know about), now it's a personal
affair, I WANT TO DO IT !!! 2 WEEKS I'VE BEEN TRYING !! AAARGH</div>
