Three.js animasyonum Vue.js'de neden daha yavaş?

Bu harika dalga simülasyonunu yeniden yaratmaya çalışıyorum: https://codepen.io/cheekymonkey/pen/vMvYNV, Vue.js'de. Ancak, onu Vue.js'de yeniden oluşturduğumda animasyon gerçekten yavaş

Vue.js yöntemleriyle aynı işlevlerin tümünü yapmayı ve değişkenleri bileşenin data özelliğine dahil etmeyi denedim.

Dalgada olması gerektiği gibi çalışır, ancak çok daha yavaştır. Bunun Vue.js'den mi yoksa onu nasıl kurduğumdan mı kaynaklandığından emin değilim. Herhangi bir tavsiye çok takdir!

Bu, davlumbazın altındaki Vue'nun örneğe bağlı her bileşeni reaktif hale getirmesi nedeniyle meydana gelir. Derinlikte Reaktivite . Geliştirme araçlarını açın ve bellek ayak izinize bakın, snippet'inizi makinemde çalıştırdığımda, ~ 20mb olan codepen örneğinin aksine ~ 300mb.

Ne zaman console.log(this.scene)ne görüyorsun getters / Vue nesneleri izlemenize olanak belirleyiciler vardır.

Aşağıdaki kod parçacığı, three.js nesnelerini Vue veri nesnesinden çeker ve bunları bir vue-statik nesneye ekler . Bu eklenti, belirli değişkenleri reaktif olmayan olarak ayarlamanıza izin verir.
