This is a fantastic article on rotations and #quaternions by @TheNumbat based on lecture notes by @keenancrane http://thenumb.at/Exponential-Rotations/ My son saw the test model there "Spot the cow", and we just had to #3dprint one and colo
But wait, there's more! I also wrote a C++ program and Lua scripts to help you make animations of these higher-dimensional fractals. You can find these at https://codeberg.org/caten/RealAlgebraPlot Not only can you see animations of the roc
Project complete! https://quaternion.cafe/ is a "vim-style" interactive tutorial that teaches sensor fusion with quaternions. It's mostly an aggregation of stuff I learned over the past few years while messing with inertial sensors. #hardwa
What “quaternions” means
WikipediaIn mathematics, the quaternions form a number system similar to the complex numbers, with the usual arithmetical operations of addition, subtraction, multiplication, and division, but with four real-number components instead of two. Unlike with the complex numbers, quaternion multiplication is not commutative, meaning that the result of multiplying two quaternions depends on their order. Quaternions can be used to represent vectors in three-dimensional space, which provides a definition of the q

every network with a public tag surfaceFollow #quaternions straight to each platform’s own tag page. Where a platform publishes open data we measure it above; the rest lock their numbers behind paid APIs, so we link rather than guess.
Every number above is measured from a named public API at the shown fetch time. Nothing is estimated or extrapolated. Platforms that lock their data behind paid APIs are not shown. Agents: the same numbers, as JSON, at /api/hashtags/quaternions
