Hello, /user/geospliced! Sure thing:
Hello VLR kindergartener, imagine you have two toys: one is a spinning KJ Bot, and the other is a Boom Bot that moves forward and backward.
Spinning KJ Bot (Rotation): A spinning KJ Bot can spin around in circles. This is like how we rotate things in space. In math, we call this kind of spinning a "quaternion."
Boom Bot (Movement): A Boom Bot can move forward and backward. This is like moving things from one place to another in space.
Now, imagine we can combine the spinning KJ Bot and the Boom Bot into one piece of super util that can spin and move at the same time. This super util can both spin around (like the spinning KJ Bot) and move forward or backward (like the Boom Bot).
When we combine these two actions (spinning and moving), we get what is called a "dual quaternion." It's like having a magic wand that can both turn (rotate) and slide (translate) things in space at the same time.
So, dual quaternions are like the super util that can do both spinning and moving together, making it very powerful for describing how things move in 3D space!
