Dual Contouring算法中描述的"Hermite Data"是什么？
What is "Hermite Data" described in the Dual Contouring algorithm?
我一直在阅读 various sources the past hours and couldn't understand how Dual Contouring works. My problem is that I don't know the meaning of "Hermite Data" and even Google and Wikipedia couldn't help me on that. Could someone explain me what "Hermite Data" is? Also I found this，它说重要的步骤在 2.2 中有描述。可悲的是我不太明白它的意思。因为在任何地方我都找不到这个方程的二次函数（的最小值）的含义的描述：
E[x] = ∑
一世
（你
·(x− pi
))2
我不知道在这个函数中 "input" 是什么，也不知道 "outputs" 是什么。他们也在谈论 "cubes" 但据我所知，一组体素只是一些数据（0 或 1），据我所知，双轮廓采用这些体素并将它们变成网格。
在这种情况下，Hermite 数据是：
- 每个顶点：
- 签名（在material的内部或外部）或material索引
- 每条边：
- 边与面的交点（可以存储为单浮点数）
- 交点处的曲面法线

有很好的解释
