  1. linear algebra - How can one intuitively think about quaternions ...

    Oct 19, 2010 · After a couple awesome moments of understanding, I understood it for imaginary numbers, but I'm still having trouble extending the thoughts to quaternions. How can someone …

  2. Real world uses of Quaternions? - Mathematics Stack Exchange

    Quaternions are a way of specifying a rotation through a axis and the cosine of half the angle. They main advantage is I can pick any two quaternions and smoothly interpolate between …

  3. Combining rotation quaternions - Mathematics Stack Exchange

    If I combine 2 rotation quaternions by multiplying them, lets say one represents some rotation around x axis and other represents some rotation around some arbitrary axis. The order of …

  4. linear algebra - Does anyone know any resources for Quaternions …

    My goal is to understand rotation quaternions specifically. I don't want to just memorize the formulas for using rotation quaternions, I want to truly understand them. It's the most difficult …

  5. Concise description of why rotation quaternions use half the angle

    Aug 5, 2015 · In my application, I make use of quaternions to represent the rotation of the device, and I feel it necessary to include a short description of what quaternions are and why they are …

  6. How do I compare the (quaternion) orientation of two objects and ...

    May 5, 2018 · You can even compare the euclidean distance of quaternions, i.e., treat them as 4D vectors and compute how much $\|q_1 - q_2\|$ differ from $0$. It works also with logarithms.

  7. 3d - Averaging quaternions - Mathematics Stack Exchange

    Given multiple quaternions representing orientations, and I want to average them. Each one has a different weight, and they all sum up to one. How can I get the average of them? Simple …

  8. rotations - How do you rotate a vector by a unit quaternion ...

    Given a 3-variable right-handed vector v that is a translation measured in local space and a unit quaternion representing an orientation from local to world space, how do you use the …

  9. Super confused by SQUAD algorithm for quaternion interpolation

    Feb 14, 2018 · The demo generates 10 random unit quaternions and then interpolates between them indefinitely. It shows 12 WebGL canvas instances, 2 per algorithm. The top canvas …

  10. difference between 2 quaternions - Mathematics Stack Exchange

    Mar 1, 2016 · Your terminology and symbolism are confusing. "Hamilton product" refers to the product of quaternions, and while vectors can be considered quaternions with 0 scalar part, …
