How to Use Quaternions and Rotation Sequences to Create Fun Clipart Games

Quaternions are a mathematical tool that can be used to describe rotations in three-dimensional space. They have many applications in computer graphics, robotics, physics, and more. One of the advantages of quaternions is that they can avoid the problem of gimbal lock, which occurs when using Euler angles to represent rotations.

Rotation sequences are a way of combining multiple rotations into one. They can be used to create complex and realistic movements for objects and characters in games. For example, a rotation sequence can be used to make a character look around, nod their head, or tilt their body.

In this article, we will show you how to use quaternions and rotation sequences to create fun clipart games using HTML5 and JavaScript. We will use the book Quaternions and Rotation Sequences by Jack B. Kuipers as a reference for the theory and formulas. We will also use some free clipart vectors from Freepik as our game assets.

Let's get started!

What are Quaternions

A quaternion is a four-dimensional complex number that can be written as:

q

=

a

+

b

i

+

c

j

+

d

k

where a, b, c, and d are real numbers, and i, j, and k are imaginary units that satisfy the following rules:

i2=j2=k2=ijk=-1

A quaternion can also be written in vector form as:

q

=

sca

larËa+vectorËv

where

scalarËa

is the real part and

vectorËv

is the imaginary part of the quaternion. The imaginary part can also be written as a three-dimensional vector:

vectorËv

=

b

i

+

c

j

+

d

k

=

bcd

The magnitude or norm of a quaternion is defined as:

=
