How to visualize 2D or 3D Rotation matrices in $\mathbb{R}^3$ or $\mathbb{R}^2$? If so, can we preserve the manifold properties? Like geodesic distance?

1Do you want to visualize the space of rotation matrices? If so, are you familiar with the more standard topological spaces that these spaces of rotations are diffeomorphic to? – J.V.Gaiter Jan 18 '24 at 21:17

1@gsoldier There is an isometric correspondence between the 2D rotation matrices (equipped with the Frobenius norm) and a circle in $\Bbb R^2$ of radius $\sqrt{2}$, but it is unclear from the phrasing of your question whether this would count as "visualizing" the matrices. – Ben Grossmann Jan 18 '24 at 21:25

I know basic topology. Can you offer more detailed hints or references? How do we build these [email protected] @Ben Grossmann – gsoldier Jan 19 '24 at 07:15

Identifying $SO(2)$ (2D rotation matrices) with $S^1$ is a simple matter of sending rotation by $\theta$ to the point at angle $\theta$ from your starting point. – Callum Jan 19 '24 at 08:44

@gsoldier Is that what you mean by “visualizing” these matrices? – Ben Grossmann Jan 19 '24 at 13:17
