I figure all geek blogs need some sort of Venn diagram to illustrate some super insightful facts of life, so I decided to go meta and do one about my
So I’m pretty sure I haven’t blogged about quaternions yet, so here goes: god damn quaternions.
Also, no blood for Euler. I’m no hippie, but we need to reduce our dependence on Euler angles and move on to a more modern, sustainable representation of orientation with no singularities. I’m not willing to send off our young men and women to die just to preserve your lazy, decadent way of determining attitude.
Here’s a sneak preview of what I’m doing these days (besides everything else):
It’s a really simple simulation framework for nonlinear recursive estimation filters for attitude determination. Like “dynamically-compiled rasterizing software renderer,” this doesn’t actually mean anything, but I’m still looking for a good acronym. If I throw in “orientation,” I get enough letters for “NOFEAR,” but “nonlinear orientation filter estimation attitude recursive” makes no sense.
By the way, the screenshot above looks crappy because I made it look crappy; I wanted to post a second screenshot later and claim that I made mad improvements to the visualizer. It actually looked pretty decent prior to the lo-fi’ing:
I’ve got a big pset due in 8 hours and an exam in 6 hours, so I guess I better stop write-crastinating.
God damn quaternions. ♥
