Those who don't understand quaternions are condemned to reinvent it, poorly.
I work in a research field that uses rotations heavily, and trying to use things like Euler angles (with 4 or 5 competing representations) and axis angles has created nothing but confusion among people. If people used quaternions from day one, it probably would have saved, cumulatively, the time of several dozen phds.
- jessaustin 7y agoWhat research field is this? Why hasn't one of the researchers made the conceptual leap you propose?
- danmg 7y agoIt has to do with metallurgy. Some people do use them, but most work is done with euler angles.
- 6gvONxR4sf7o 7y agoI think you misunderstand the article. It's not saying to replace them with euler angles or axis angles or anything analogous. GA is among other things a more intuitive mental model of quaternions.
