Quaternion - Axis, Angle Visualization

I’ve been using quaternions. Because rotation in space is not easy, I was looking for a simple visualization. I found a lot of theory about quaternions and a workable converter. http://www.energid.com/resources/orientation-calculator/ But no visualization for my own requirements. So I created it myself. Quaternion and axis, angle are continuously converted into each other. [quaternion] If you want to try the little helper, you will find him there: http://threejs.hofk.de/ or directly ther…

Quaternion - method .setFromBasis( e1, e2, e3 )

These posts and examples are about movement on a curve. Struggling with paths - #14 by hofk Car Racing - For lovers of fast cars! MotionAlongCurve MovementOnCurve CarRacing However, the solution via matrices requires computational effort. I have been looking for a solution with quaternions that requires fewer formula steps. The solution is a new method in the quaternion class. I added it to three.module.129.Quaternion.js in the example BasisToQuaternion. This makes the calculat…
