| //Moebius transformations in 3d, by reverse stereographic projection to the 3-sphere, | |
| //rotation in 4d space, and projection back. | |
| //by Daniel Piker 09/08/20 | |
| //Feel free to use, adapt and reshare. I'd appreciate a mention if you post something using this. | |
| //You can also now find this transformation as a component in Grasshopper/Rhino | |
| //I first wrote about these transformations here: | |
| //https://spacesymmetrystructure.wordpress.com/2008/12/11/4-dimensional-rotations/ | |
| //If you want to transform about a given circle. Points on the circle and its axis stay on those curves. | |
| //You can skip these 2 lines if you want to always use the origin centred unit circle. |
