Vector

    npm install flexible-vector

flexible vector tooling for typescript and javascript. Supporting numeric component access, iterator protocol and flexible name based access.

    import {vector} from 'flexible-vector';

    let v1 = vector(1,2,3);
    v1[2];          // 3;
    v1.get(2);      // 3;

supports flexible components accessors

use vector2, vector3 and vector4 to get augmented vectors that have special accessors.

vector2 has x, y and permutations thereof vector3 has r,g,b and x,y,z and permutations thereof vector4 has r,g,b,a and x,y,z and permutations thereof

    import {vector3} from 'flexible-vector';

    let v1 = vector3(1,2,3);
    v1.rg;  // vector(1,2);

    // or even permutations
    v1.bgr; // vector(3,2,1);

Setters are also supported, however, we discourage their use. Better to treat vectors as immutable.

    let v1 = vector3(1,2,3);
    v1[2] = 5;
    v1.xy = v1.yz;
    v1.z = 6;   //vector(2,5,6);

supports iterator pattern

    import {vector} from 'flexible-vector';

    let v1 = vector(1,2,3);
    [...v];         // [1,2,3];

supports vector operations

• norm the norm of the vector
• normalize normalize the vector (length to 1 or 0)
• dot dot product of two (equal size) vectors
• plus addition of two (equal size) vectors
• minus addition of two (equal size) vectors
• times multiplication by a scalar
• equals check whether a vector equals another
