Except for one thing: you don't have a good reason to use quaternions yet.───但除了一件事情，你还没有明白为何要使用四元数的原因。
You pretty much know all the important stuff about quaternions now.───你现在几乎获得了所有关于四元数的重要信息。
Of course, you'll also need to be able to convert from "conventional" representations to quaternions.───当然，你可能也会用到四元数转换的“常规”表示法。
Quaternions, which extend imaginary numbers into a further dimension, began to be developed by William Hamilton in Dublin in 1843.───1843年，威廉•汉密尔顿（WilliamHamilton）在都柏林发明了四元数，将虚数扩展到四维空间。
W component of the Quaternion. Don't modify this directly unless you know quaternions inside out.───四元数的W组件。不要直接修改这个，除非你很了解四元数。
Of course, you'll also need to be able to convert from "conventional" representations to quaternions.───当然，你可能也会用到四元数转换的“常规”表示法。
Only the bone data needs to be stored for every frame of the animation. Usually, the bone data is represented by quaternions.───存储动画帧我们仅仅需要骨胳的数据。通常，骨胳数据由四元数表示。
Quaternions extend the concept of rotation in three dimensions to rotation in four dimensions.───四元数将三维中旋转的概念扩展到四维中的旋转。
Determines the product of a quaternions and a specified factor.───确定四元数与指定因数的乘积。
Vector is a useless survival, or offshoot from quaternions.
First, the probabilistic model of the rounding error in the computation of quaternions on a fixed point computer is established. Then, the probabilistic rounding error estimates are computed.
The attitude kinematics and dynamics are both described by error quaternions.
This paper contains two parts:1. Algebraic operations of quaternion are defined by utilizing the knowledge in vector algebra and the fundamental properties of algebra of quaternions are derived.
Only unit quaternions represent rotations, so normalize your quaternions if you have to.
