Computing a Basis

admin No Comment

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.

The school year is under way and as educators, students, and families fall into a new, yet familiar rhythm, the business of learning begins.
