Filter

过滤器

Don’t be surprised that all filters are described on a single page. We will be using one and the same object only with different settings.

不要惊讶所有的过滤器都在一个单独的页面上描述。我们将使用一个和同一个对象只有不同的设置。

Strength[0..100%]

力量[0. . 100% ]

This slider is used to adjust the strength of the filter.

这个滑块用于调整过滤器的强度。

类型

Here you will find a description of the Volume TypeSigned Distance Field.

在这里你会找到一个描述的体积排版的距离字段。

Note that the Smooth filter’s settings are identical to the SDF, Fog and Vector options and are therefore also shown here.

请注意，平滑过滤器的设置是相同的 SDF，雾和矢量选项，因此也显示在这里。

Smooth

真顺利

The Smooth filter smoothes the transition of Voxel values.

光滑滤波器平滑了体素值的转换。

Dilate / Erode

膨胀/侵蚀

Depending if the Offset has a negative or positive value, the surface will be offset inwardly or outwardly.

取决于偏移量是负值还是正值，表面将向内或向外偏移。

Close / Open

关闭/打开

Depending if the Offset setting has a positive or negative value, the outer surfaces will first be moved inwardly and by the same distance outwardly (closes holes and smoothes details, for example) or these surfaces will first be moved outwardly and then by the same distance inwardly (connects objects that lie in close proximity).

取决于偏移设置是正值还是负值，外表面将首先向内移动和向外移动相同的距离(关闭孔和平滑细节，例如)或者这些表面将首先向外移动，然后向内移动相同的距离(连接位于近处的物体)。

These filters can produce very interesting results. As always, it’s a good idea to experiment. You can, for example, use Hair (the Hair object can generate both splines and polygons) in a Volume Builder. Interesting structures can be created using these filters:

这些过滤器可以产生非常有趣的结果。一如既往，实验是个好主意。例如，您可以在体积生成器中使用 Hair (Hair 对象可以同时生成样条和多边形)。使用这些过滤器可以创建有趣的结构:

The following is done to render the current Voxel:

下面是渲染当前体素的步骤:

• Gaussian 高斯分布: neighboring Voxel values wil be used based on a Gaussian curve. : 邻近的体素值将用于基于高斯曲线
• Mean 刻薄: the mean value of the neighboring Voxel values will be used (corresponds to a rectangular filter) : 使用相邻体素值的平均值(相当于一个矩形滤波器)
• Median 中位数: the Mean value (median value of the ordered Voxel value list) of the neighboring Voxel values will be used. The local maximums (peaks) will be ignored. : 使用邻近体素值的平均值(有序体素值列表的中位数值)。局部最大值(峰值)将被忽略
• Mean Curvature 平均曲率 (only SDF): the average curvature will be ascertained and applied at each position. Soap film, for example, behaves like this. This can be used to smooth minor irregularities. (只有 SDF) : 平均曲率将确定和适用于每个位置。例如，肥皂膜就是这样的。这可以用来平滑较小的不规则
• Laplacian Flow 拉普拉斯流 (only SDF): with an increasing (只有可转移自由基) :Iterations 迭代 value and a largely consistent volume, maximums will be reduced accordingly. 价值和一个基本上一致的数量，最大限度将相应减少

This is all rather abstract. Since the results are often similar, the best thing you can do is experiment in your scene to see which results are produced.

这些都是相当抽象的。由于结果往往是相似的，你能做的最好的事情就是在你的场景中进行实验，看看哪些结果是产生的。

Voxel Distance[1..2147483647]

体素距离[1.2147483647]

This value can not be defined for all Filter Types.

不能为所有筛选器类型定义此值。

This value defines how many neighboring Voxels (in all 6 directions), in a cube-shaped area, will be used to further calculate the individual Voxel. The greater the value, the broader the smoothing effect will be. Render times will increase accordingly as the value increases!

这个值定义了在一个立方体形状的区域中有多少相邻的体素(在所有6个方向上)将被用来进一步计算单个体素。值越大，平滑效果就越明显。渲染时间将随着价值的增加而相应增加！

Offset[-∞..+∞m]

偏移量[-∞ . . + ∞ m ]

This value is added to each Voxel value. Negative values are also possible. In practice, this means that the surface will be raised or sunken for most filter types.

这个值被添加到每个体素值中。负值也是可能的。实际上，这意味着对于大多数过滤器类型来说，表面会凸起或凹陷。

Iterations[1..2147483647]

迭代[1.2147483647]

Here you can define how often the filter should be applied. The render time will increase accordingly with increasing values and the filter effect will be stronger.

这里您可以定义过滤器应用的频率。渲染时间会随着值的增加而增加，滤镜效果会更强。

Filter Accuracy

过滤器的准确性

Here you can select from 6 filters. These define how precisely or exactly the calculations should be made. The filters are arranged in order of increasing accuracy per type (Bias or Weno) from top to bottom (render times will increase accordingly). Test each one to find out which one works best for your respective scene.

这里你可以从6个过滤器中选择。它们定义了应该如何精确或准确地进行计算。过滤器的排列顺序增加每类型的准确性(偏见或温诺)从上到下(渲染时间将相应增加)。测试每一个，找出哪一个最适合你各自的场景。

Resize
Voxel Range[1..2147483647]

距离[1.2147483647]

These settings are used to create more volume so the filter can work better. This is a reference to the problems described here. Note the hierarchy and the order in which the filters are arranged in the object list (processed from top to bottom!). The volume resize is only applied to the volumes directly below it. Objects that appear later in the list are not affected.

这些设置用于创建更大的音量，以便过滤器能够更好地工作。这里提到的是这里描述的问题。注意层次结构和过滤器在对象列表中的排列顺序(从上到下处理!).体积调整大小只适用于其下方的体积。列表中稍后出现的对象不受影响。

However, Voxel Range will generate Voxel layers both above and below the original surface. This can be defined separately in the Volume Builder, which can result in faster calculations (and is definitely the recommended and more precise method).

然而，体素范围将产生体素层之上和之下的原始表面。这可以在体积生成器中单独定义，这可以导致更快的计算(这绝对是推荐的和更精确的方法)。

Smooth

真顺利

The Smooth filter smoothes the Voxel transitions (see Signed Distance Field above).

光滑过滤器平滑体素转换(见上面的签名距离字段)。

Curve

曲线

Here, the value range can be converted not linearly but using a spline.

这里，值范围可以使用样条进行非线性转换。

Multiply

繁殖

This filter multiplies the current Voxel value with a multiplier defined below.

此过滤器将当前体素值乘以下面定义的乘数。

Invert

This mode mirrors the Voxel value range around a mean value or a freely definable center point.

这种模式反映了围绕一个平均值或一个自由定义的中心点的体素值范围。

Add

添加

Use this mode to add the Voxel values to the Add setting that appears.

使用此模式将体素值添加到出现的 Add 设置中。

Range Map

量程图

Works like the Range Mapper XPresso node. A Voxel value range will be converted linearly to another value range (see below).

工作原理类似于 Range Mapper XPresso 节点。体素值范围将线性转换为另一个值范围(见下文)。

Multiply[-∞..+∞]
Add[-∞..+∞]

乘[-∞ . . + ∞]加[-∞ . . + ∞]

Here, you can enter the values for the Multiply and Add modes described above.

在这里，您可以输入上面描述的乘法和加法模式的值。

Auto-detect Center
Mirror Around[-∞..+∞]

[-∞ . . + ∞]周围的自动检测中心反射镜

These settings will be made available if Type is set to Invert. Auto-Detect Center uses the largest and smallest Voxel values to ascertain a mean value on whose basis the value range will be mirrored. Disable this option if you want to freely define the mirror mean value using the Mirror setting.

如果 Type 设置为 Invert，这些设置将可用。自动检测中心使用最大和最小的体素值来确定一个平均值，其基础值范围将被镜像。如果您想自由地使用 Mirror 设置定义镜像平均值，请禁用此选项。

Min Input[-∞..+∞]
Min Output[-∞..+∞]
Max Input[-∞..+∞]
Max Output[-∞..+∞]

Min Input [-∞ . . + ∞] Min Output [-∞ . + ∞] Max Input [-∞ . . + ∞] Max Output [-∞ . . + ∞]

If Type is set to Range Map, the Voxel range will be replaced by a new one (similar to the Range Mapper XPresso node). The Min and Max settings can be used to define this very precisely.

如果 Type 设置为 Range Map，那么体素范围将被一个新的范围替换(类似于 Range Mapper XPresso 节点)。最小和最大的设置可以用来非常精确地定义这一点。

Example: these 4 Voxel values are present: 0, 1, 4, 5.

例如: 这4个体素值表示为: 0,1,4,5。

• If you set 如果你设置Min Input 最小输入 to 到0 and 及Max Input 最大输入 to 到5, Min Output 最小输出 to 到0 and 及Max Ouput 马克斯 · 乌普特 to 到10, 0, 2, 8 and 10 will result. 0,2,8,10
• If you set 如果你设置Min Input 最小输入 to 到0 and 及Max Input 最大输入 to 到5, Min Ouput to 到2 and 及Max Output 最大输出 to 到8, 2, 3.2, 6.8 and 8 will result. 2,3.2,6.8和8
The Voxel values will be transferred proportionally to the new value range. 体素值将按比例转移到新的值范围

This is useful if a value range is incompatible with another. Example: A grid’s Voxel values range from 0.1 - 0.2. A shader, for example, works best with values between 0 and 100. By entering exactly these 4 values, the best possible result will be achieved.

如果一个值范围与另一个值范围不兼容，这是有用的。示例: 网格的体素值范围为0.1-0.2。例如，着色器在0到100之间效果最好。只要输入这4个值，就可以得到最好的结果。

Shape

形状

If Type is set to Curve, the Voxel range will be converted based on this definable spline (and not linearly as with Range Map).

如果类型设置为曲线，体素范围将转换基于这个可定义的样条(而不是线性与范围映射)。

类型

If Volume Type is set to Vector, 6 options are available for affecting the Volume Vectors:

如果体积类型设置为 Vector，则有6个选项可用于影响体积向量:

• Smooth 真顺利: Aligns the orientation of the vectors to each other within the Voxel Distnce : 在体素距离内将矢量的方向对齐
• Curl 体积发: Converts the existing vector field into a special new one (see Curl below). : 将现有的向量场转换为特殊的新向量场(参见下面的 Curl)
• Normalize 正常化: Sets all directional vectors to a constant length of 1. : 将所有方向向量设置为常量长度1
• Invert: Inverts all directional vectors, which means the effect will be in the opposite direction.. : 反转所有方向矢量，这意味着效果将在相反的方向。
• Scale 比例: Scales the directional vector length using a value defined by the 方法定义的值缩放方向向量长度Scale 比例 setting. 设置
• Rotate 轮流: Rotates all vectors around a definable axis (see Rotate below). : 围绕一个可定义的轴旋转所有向量(请参阅下面的“旋转”)

Curl

体积发

Curl converts an existing volume vector and is a function that converts the existing volume vectors in a special way. To explain this in detail would take us into the depths of math. This is why only the main purpose of this filter will be explained: It creates random fields (noise) from vectors that always target the null region of the noise - particles can get caught up here - vectors that produce looping movements with circular or vortex-like paths (see also Field Force object).

Curl 转换现有的体积向量，是一个函数，用特殊的方式转换现有的体积向量。详细地解释这一现象将把我们带入数学的深处。这就是为什么这个过滤器的主要用途将得到解释: 它创建随机场(噪声)从矢量总是针对零区域的噪声-粒子可以在这里捕获-矢量产生循环运动与圆形或涡旋一样的路径(也见场力对象)。

This is illustrated in the image above. On the left the particles remain stuck in certain regions and on the right they continue their movement.

这在上面的图片中得到了说明。左边的粒子停留在某些区域，右边的粒子继续运动。

Rotate

轮流

If Rotate is selected, each individual vector (representative for all vectors per Voxel) will be rotated around its axis at its origin.

如果选择了 Rotate，每个单独的矢量(每个体素代表所有矢量)将在其原点绕其轴旋转。

Axis

轴心

Here you can define the rotational axis starting from the Volume Builder’s object coordinate system. If Custom is selected, a unique vector can be defined:

在这里你可以定义旋转轴开始从体积生成器的对象坐标系。如果选择 Custom，则可以定义一个唯一的矢量:

Vector[XYZ ]

向量[ XYZ ]

Here you can define the axis direction around which the vector should rotate. 1, 0, 0 will define a vector parallel to the X axis and 0, 1, 0 parallel to the Y axis. The Volume Builder’s object coordinate system will be used.

这里您可以定义向量应该旋转的轴方向。1,0,0将定义一个平行于 x 轴和0,1,0平行于 y 轴的矢量。体积生成器的对象坐标系将被使用。

Angle[-∞..+∞°]

角度[-∞ . . + ∞ ° ]

Here you can define the angle around which the vectors should rotate.

这里你可以定义向量应该旋转的角度。

Scale

比例

The following settings are available for the Scale function:

下面的设置可用于 Scale 函数:

Scale[-∞..+∞]

刻度[-∞ . . + ∞]

Use this setting to scale the length of the directional vector. A value of -1 will reflect the Invert function’s behavior.

使用此设置可缩放方向向量的长度。值-1将反映反转函数的行为。
