We are currently in the process of converting the website to the new design. Some pages, like this one, are still broken. We appreciate your patience.
I like the transition between unsure "may be" to confident "it is" :) Is it because you checked t…
What I should have said is "you cannot represent all angles uniquely". "3 divides may be more expe…
Excuse me? Length of a vector, not lost but assumed to be one. I lost exactly 1 advantage, rota…
At some point it needs to be rotated 180° compared to the starting position. At that point your …
3 divides may be more expensive than 7 multiplies. Show me the empirical evidence, not theoretical…
Yes, and for Gibbs vectors this information is . Because , it equals to , these are versors. So w…
Which is kind of my point. RPs cannot be used to store an orientation which can then be used as a …
[/quote] zero rotation is 0,0,0,1 and full 360 rotation is 0,0,0,-1. There is no axis information…
Quaternions are used for storing an orientation, not just rotations. RPs cannot do this. I'll repe…
ratchetfreak's problem is not a problem for unit quaternions (and Gibbs vectors are of unit lengt…
First off, how do you encode an zero rotation, half a turn or a full turn around a particular axis…
It is not, until proven otherwise. I can't make dot product return 1, if you know how let us know…
It actually is a problem. RPs can be zero unlike quaternions. Other than curiosity, I see no benef…

It worked! Thank you so much. I'll make sure to use tags from now on, too. Again, thank you!
I was asking to execute "PATH" command and show the output. From the code you posted it looks like…

I will not guard my code against divide by 0 anywhere other than in vector length procedure... Wi…
The code is updated for extracting an axis and angle from a Gibbs vector.
With unit quaternions, there is no worry with dividing by zero. However, with Rodrigues/Gibbs Para…
Isn't any divide in any math code ever suffers from the same problem? I will not guard my code ag…
The problem is not about hitting value exactly 0 or 180 or any other. The problem with floats is …
there is also the chance that a.w * b.w - (a.x * b.x + a.y * b.y + a.z * b.z) = 1-dot(A, B) will …
, so even if Gibbs vectors fail somehow you can always fallback to them. Right, in that case I w…
