Faster quaternion product rotations

1 · John Cook · June 16, 2021, 1:27 p.m.
You can use quaternions to describe rotations and quaternion products to carry out these rotations. These products have the form qpq* where q represents a rotation, q* is its conjugate, and p is the the vector being rotated. (That’s leaving out some details that we’ll get to shortly.) The primary advantage of using quaternions to […] The post Faster quaternion product rotations first appeared on John D. Cook....
