find-basis-3d
Given a single "up" vector, finds a triple of orthogonal basis vectors such that the first two are orthogonal to the last, which is parallel to the input vector. This can be used to assign tangent spaces to flat planes.
Install
npm install find-basis-3d
Example
var findBasis = require("find-basis-3d")
var normal = [1, 0.5, 0]
console.log(findBasis(normal))
require("find-basis-3d")(up)
Finds an orthonormal basis aligned along up
.
up
is the z-vector for the new basis
Returns An array of 3 vectors, where the first two vectors are orthogonal to up
, and the last is parallel. All vectors are orthonormal.
