Given a normalized 3D vector, here’s an efficient method for computing a full basis. The computed basis is axis aligned if the input vector is axis aligned.
void ComputeBasis(const Vec& a, Vec* b, Vec* c)
// Suppose vector a has all equal components and is a unit vector: a = (s, s, s)
// Then 3*s*s = 1, s = sqrt(1/3) = 0.57735. This means that at least one component of a
// unit vector must be greater or equal to 0.57735.

4-H Engages Youth in an Outreach STEM Program
Monday October 22, 2018
The two worlds of Agriculture and Science, Technology, Engineering and Math, or STEM, had a group of 4-H students shooting for the stars in a recent Youth Lab. The out-of-this-world lesson was part of the National 4-H Science mission mandate, which is designed to address the following: unsolved worldwide social problems, a shortage of scientists […]
