- What is the definition of unit vector? - Physics Stack Exchange
So a unit vector is a mathematical object that is different from a vector of length 1 [UNIT], be it meters, Newtons, whatever This is because by definition the unit vector has no physical units, since its given by the ratio of the vector by its norm (and vector and norm always have the same physical units)
- Confusion about unit vectors - Physics Stack Exchange
By definition, A unit vector is a vector with magnitude $1$ But, what does this even mean? Shouldn't the magnitude come with units like cm, m, inches etc ? Upon reading more about this, I've come to
- What is a formula to get a vector perpendicular to another vector?
In 3 dimensions, there are infinitely many different vectors (a 2-dimensional vector space) perpendicular to a given vector There is no single vector that a formula would generate
- Finding quaternion representing the rotation from one vector to another
I have two vectors u and v Is there a way of finding a quaternion representing the rotation from u to v?
- math - Rotating a Vector in 3D Space - Stack Overflow
Rotating a vector around the origin (a point) in 2D simply means rotating it around the Z-axis (a line) in 3D; since we're rotating around Z-axis, its coordinate should be kept constant i e 0° (rotation happens on the XY plane in 3D)
- Does the magnitude of a physical quantity have units or is it just a . . .
I think you could develop a perfectly good mathematical system where units are kept in the direction vector (so it would really be a "direction-unit vector") The problem is just that it would be less useful than a system where the units are kept separate, because you'd need different unit vectors for different types of quantities
- What is the need for normalizing a vector? - Stack Overflow
Hence, unit vectors are extremely useful for providing directions Note however, that all the above discussion was for 3 dimensional Cartesian coordinates (x, y, z) But what do we really mean by Cartesian coordinates? Turns out, to define a vector in 3D space, we need some reference directions
- Why do we need a Unit Vector (in other words, why do we need to . . .
I am reading a book on game AI One of the terms that is being used is to normalize a vector which is to turn a vector into a unit To do so you must divide each dimension x, y and z by its magni
- How to get Yaw, Pitch and Roll from a 3D vector - Stack Overflow
I have a direction vector that applied to a position gives me the point at which the camera should look How can I get from that yaw, pitch and roll in order to use glRotatef properly? Thanks in a
