Great article! I didn't know about Rotation Minimizing Frames or the double reflection method.
I've run up against the issue of unexpected twisting of splines at work more than once.
- TheRealPomax 4y agoThey're also known as Frenet frames, or Bishop frames, if you're going to dig into them in the future.
- Jasper_ 4y agoFrenet frames are simply any orthonormal frame. A rotation-minimizing frame is a frame that has minimal twist from some previous frame.
- TheRealPomax 4y agoWhat they are, and what people call things, are two different things though. Ran into lots of folks calling them Frenet frames while looking this up myself several years ago.
- Voltage 4y agoThanks for the tip. I thought I recognized your handle! You wrote the "A Primer on Bézier Curves" article. Thanks for providing that amazing resource, it's been invaluable during my learning process.
- TheRealPomax 4y agoI did indeed, always nice to hear folks enjoyed it!
