<div class="moz-cite-prefix">Sorry Guys,<br>
but I don't get your source in target thing. <br>
All our transformations are simply a transformation from a frame<br>
A to a frame B. This corresponds with the naming scheme of
source and<br>
target and 'body2Odometry'<br>
Also <br>
Point_b = a2b * Point_a<br>
is for me a completely logical way of writing this down.<br>

Just for the small difference that in reality (in a mathematical
meaning) is<br>
point_b = (a2b)^-1 * point_a<br>
<br>
What you are calling a2b in reality is b2a in terms of transforming
frames (b2a = (a2b)^-1 )<br>
In your case you are not transforming frames you are transforming
points expressed in frames. This is what Alex called as "Source in
target" thing. It is not more than "a expressed with respect to b"
which is b2a.<br>
<br>
I hope it helps<br>

<div class="moz-cite-prefix">Hi Alex,<br>
Thanks for taking the initiative. It is clear to me and there
is not doubt when using static transformations.<br>
However, I added the case when using dynamic transformations.
Please fill free to edit as well.<br>
