性能粒子系统

Question

我有30,000个顶点，尝试为它们制作动画，但此时性能下降有关于如何改进代码的建议吗？

function createParticle() {
  let tween;
  _.times(30000, n => {
    let vertex = shirt.geometry.vertices[n];
    let particle = particles.vertices[n];
    particle.x = 15 * 20;
    particle.y = 16 * 20;
    particle.z = 14 * 20;

    tween = new TWEEN.Tween(particle)
      .to({
        x: vertex.x * shirt.scale.x,
        y: vertex.y * shirt.scale.y,
        z: vertex.z * shirt.scale.z
      }, 3000)
      .onUpdate(function() {
        particleSystem.geometry.verticesNeedUpdate = true;
      })
      .easing(TWEEN.Easing.Sinusoidal.InOut)
      .start();
  });
}
