force-n-body v1.0.7

force-n-body

Force-n-body algorithm with Barnes-Hut Algorithm acceleration.

API

• nodes: nodes to compute forces
• weightFunc: each node's weight specifying function, default is () => 30
• return: force vectors array

function forceNBody(
  nodes: { x: number; y: number }[],
  weightFunc?: (node?: { x: number; y: number }) => number
): { vx: number; vy: number }[];

function forceNBodyBruteForce(
  nodes: { x: number; y: number }[],
  weightFunc?: (node?: { x: number; y: number }) => number
): { vx: number; vy: number }[];
