ios - 做变形动画时如何软化

Question

当我为模型使用变形动画时，模型会自动变成硬边。我们应该如何避免这种变化？

let animation = CABasicAnimation(keyPath: "morpher.weights[0]")
animation.fromValue = 0.0
animation.toValue = 1.0
animation.autoreverses = true
animation.repeatCount = MAXFLOAT
animation.duration = 0.25
face.addAnimation(animation, forKey: nil)

here is the animation

Answer 1

There could be three potential problems causing your model to show hard edges at animation:

• 3D 模型(低多边形模型)中的多边形数量不足
• 源模型和目标模型的多边形数量不同
• 模特有板面，non-manifold geo , 或非平面

据推测，您可能会同时遇到列出的所有问题，或者只有其中一个。
