矢量运算节点
矢量运算节点。
矢量运算 节点对输入矢量执行选定的数学运算。
输入
节点的输入是动态的。 某些输入仅在某些操作中可用。 例如， 缩放 输入仅在 缩放 运算符中可用。
- 矢量
Input vector \(A = \begin{pmatrix} A_x \\ A_y \\ A_z \end{pmatrix}\).

属性
- 操作
矢量数学运算符将应用于输入矢量。
- 相加
The sum of A and B. \(\begin{pmatrix} A_x + B_x \\ A_y + B_y \\ A_z + B_z \end{pmatrix}\)
- 相减
The difference between A and B. \(\begin{pmatrix} A_x - B_x \\ A_y - B_y \\ A_z - B_z \end{pmatrix}\)
- 正片叠底（相乘）
The entrywise product of A and B. \(\begin{pmatrix} A_x \cdot B_x \\ A_y \cdot B_y \\ A_z \cdot B_z \end{pmatrix}\)
- 相除
The entrywise division of A by B. Division by zero results in zero. \(\begin{pmatrix} A_x / B_x \\ A_y / B_y \\ A_z / B_z \end{pmatrix}\)
- 乘后再加
The entrywise combination of the multiply and addition operations. \(A * B + C\)
- 叉乘
The cross product of A and B. \(\begin{pmatrix} A_y \cdot B_z - A_z \cdot B_y \\ A_z \cdot B_x - A_x \cdot B_z \\ A_x \cdot B_y - A_y \cdot B_x \end{pmatrix}\)
- 投影
A在B上的投影。
- 反射
The reflection of A around the normal B. B need not be normalized.
- 折射
For a given incident vector A, surface normal B and ratio of indices of refraction (IOR), refract outputs the refraction vector R.
- 面朝前
Orients a vector A to point away from a surface B as defined by its normal C. Computes \((dot(B, C) < 0) ? A : -A\).
- 点乘
The dot product of A and B. \(A_x \cdot B_x + A_y \cdot B_y + A_z \cdot B_z\)
- 距离
A和B之间的距离。
- 长度
The length of A. \(\sqrt{A_x^2 + A_y^2 + A_z^2}\)
- 比例|缩放
The result of multiplying A by the scalar input Scale. \(\begin{pmatrix} s \cdot A_x \\ s \cdot A_y \\ s \cdot A_z \end{pmatrix}\)
- 规格化
The result of normalizing A. The result vector points to the same direction as A and has a length of 1. If A is (0, 0, 0), the result is (0, 0, 0) as well.
- 包裹

- 余弦
The entrywise Cosine of A.
- 切向(正切)
The entrywise Tangent of A.
输出
