butiran-js

Node package for simulation of grain-based system using molecular dynamics method and agent-based model

module

• vect3
  • Vect3() Initialize with three, one, or zero arguments
  • strval() Get string value of a Vect3
  • add() Add some Vect3
  • sub() Substract two Vect3
  • mul() Multiply Vect3 with scalar or vice versa
  • div() Divide Vect3 with scalar
  • dot() Dot two Vect3
  • cross() Cross two Vect3
  • len() Get length of a Vect3
  • unit() Get unit vector of a Vect3
  • neg() Get negative of a vector

usage

var butiran = require("butiran");
var Vect3 = butiran.Vect3();

var a = new Vect3(3, 4, 0);
console.log(a);
console.log("a = " + a.strval());

var b = new Vect3(4, -3, 0);
console.log("b = " + b.strval());

var c = Vect3.cross(a, b);
console.log("a x b = " + c.strval());

var d = Vect3.dot(a, b);
console.log("a . b = " + d);

Vect3 { x: 3, y: 4, z: 0 }
a = (3, 4, 0)
b = (4, -3, 0)
a x b = (0, 0, -25)
a . b = 0
