General 3D rotations via non-square matrices. Generalizable to any n Haven't seen this anywhere, but it's got to be the most logical way of treating the whole subject of rotations. Uses "extractive projections" via the 2x3 Posted - Tue Jun 18, 2013 1:48 pm	Christopher Young c56young Send Email
Earth spinning on its axis via extractive and embedding projections. Just checking that the formula works for solid objects. Had to fiddle around to get the spinning globe aligned with its equator on the plane, but that's no Posted - Tue Jun 18, 2013 1:47 pm	Christopher Young c56young Send Email

Rotation parallel to a plane via non-square matrices I think this is is simpler than most other methods I've seen. I'm looking for something I can use to do rotations in 4D parallel to an arbitrary plane. This is Posted - Tue Jun 18, 2013 12:48 pm	Christopher Young c56young Send Email
Hypercube projected onto diagonal hyperplane. Generalized cross-prod The projection of a cube onto the diagonal plane specified by x + y + z = 0 will yield a hexagon with each of the parallelograms taking up two segments. Posted - Mon May 6, 2013 10:09 am	Christopher Young c56young Send Email
