What is Improved Orthonormal Basis Method about?

This document summarizes a paper that identifies and addresses a precision problem in an existing, widely-used computational method for efficiently generating an orthonormal basis from a given unit vector. The original method works well in most cases but can produce dramatically inaccurate results when the input vector has a z-component close to -1 due to catastrophic cancellation from floating point subtraction. The paper presents an analysis of the problem and introduces a revised implementation that avoi
