Projective 3-sphere

In mechanics and geometry, the 3D rotation group is the group of all rotations about the origin (mathematics) of three-dimensional Euclidean space R3 under the operation of composition. By definition, a rotation about the origin is a transformation that preserves the origin, Euclidean distance (such as it is an isometry), and orientation (i.e. handedness of space). A distance-preserving transformation which reverses orientation is an improper rotation, that is a reflection or, in the general position, a rotoreflection. The origin in Euclidean space establishes certain one-to-one correspondence between points and their coordinate vectors. Rotations about the origin can be thought of as magnitude-preserving linear transformations of Euclidean 3-dimensional vectors (whose vector space is also denoted as R3).

Composing two rotations results in another rotation; every rotation has a unique inverse rotation; and the identity map satisfies the definition of a rotation. Owing to the above properties (along with the associative property, which rotations obey), the set of all rotations is a group under composition. Moreover, the rotation group has a natural manifold structure for which the group operations are smooth; so it is in fact a Lie group. The rotation group is often denoted SO(3) (or, less ambiguously, SO(3, R)) for reasons explained below.

Visualizing High Dimensional Data: Azhimutal projection for RPM on projective spaces

Among those manifolds used by relational perspective map (RPM), the 2-dimensional real projective plane (P2) has been one of my favorite space. As a visualization space for high dimensional data, P2 works similarly as the 2-dimensional flat torus (T2) used initially by RPM.

Rolling Circles and Balls (Part 5) | Azimuth

Last time I promised to show you how the problem of a little ball rolling on a big stationary ball can be described using an 8-dimensional number system called the split octonions… if the big ball has a radius that’s 3 times the radius of the little one!
So, let’s get started.
First, I must admit that I lied.
