使用 Cyl.距离效果
These settings are almost identical to those on the Distance page. To switch on the cylindrical effect, enable the Use Cyl.Distance Effects option.
这些设置与距离页面上的设置几乎完全相同。要打开圆柱效果，请启用“使用 Cyl”。距离效果选项。
With these settings, two invisible concentric cylinders are notionally positioned on top of the emitter, facing in the direction that particles are being emitted. Puffs in the cavity between the inner and outer cylinders may have their color, radius and luminosity adjusted according to how far away they are from the inner cylinder. This enables you to create effects that are more or less cylindrical in shape, such as smoke forming around a column of fire. This is contrast to the sphere used on the Distance page.
有了这些设置，两个看不见的同心圆柱理论上定位在发射器的顶部，朝向粒子发射的方向。在内外筒之间的空腔中的气泡可以根据它们离内筒的距离调整颜色、半径和亮度。这使您能够创建或多或少呈圆柱形的效果，例如在火柱周围形成烟雾。这与在距离页面中使用的球体形成了对比。
Note: All PyroCluster effects (age, emitter distance, radial, distance) can be used simultaneously. The result, though, may not be the one that was desired. Depending on the settings used, the distance effect, for example, could receive a greater priority than the age effect. 注: 所有 PyroCluster 效果(年龄，发射器距离，径向，距离)可以同时使用。然而，结果可能并不是人们所期望的。根据使用的设置，距离效果，例如，可以得到比年龄效果更大的优先权

发射器方向
Set this option to the direction in which the emitter emits particles.
将此选项设置为发射器发射粒子的方向。
In the example below, the z axis was defined as the direction in which the emitter should emit particles.
在下面的示例中，z 轴被定义为发射器应该发射粒子的方向。
近距离[0. . + ∞ m ]
Use this world unit setting to define the volume’s radius that controls the begin of the parameter change (distance color, mix and radius).
使用此世界单位设置来定义控制参数改变开始的体积半径(距离颜色、混合和半径)。
远距离[0. . + ∞ m ]
Use this world unit setting to define the volume’s radius that controls the end of the parameter change (distance color, mix and radius).
使用此世界单位设置来定义控制参数变化(距离颜色、混合和半径)结束的体积半径。
Note: If the Near Range is set to 注意: 如果近距离设置为0.0 the parameter change will begin with the very first particle. A Near Range setting of 50 will cause the particles to be drawn as a puff in a radial distance of 50 world units from the emitter using the defined start settings (left end of gradient). Particles located farther than 50 units from the emitter will be interpolated between the Near and Far Range (start & end) values. 参数的改变将从第一个粒子开始。近距离设置为50将导致粒子被绘制为一个泡芙在径向距离50个世界单位从发射器使用定义的开始设置(左端的梯度)。距离发射器50单位以外的粒子将在近距离和远距离(开始和结束)值之间插值In the image below, the cylinder represents the Near Range.:
在下面的图片中，圆柱体代表了近距离射程:
半径
The radial distance radius defines the puff’s radius based on the distance of the puff from the emitter. The PyroCluster’s volume radius is represented by the color at the left end of the grayscale gradient. The right end of the gradient represents the Far Range.
径向距离半径根据喷气到发射器的距离确定喷气半径。PyroCluster 的体积半径由灰度梯度左端的颜色表示。渐变的右端代表远距离。
Note: If you turn on the shape preview the change in size of the PyroCluster volume can be seen directly in the editor view. 注意: 如果您打开形状预览，可以在编辑器视图中直接看到 PyroCluster 体积大小的变化例子:

亮度
The Luminosity gradient controls the luminosity of puffs within the cavity.
亮度梯度控制腔内喷出物的亮度。
These gradients control the radius and luminosity of puffs depending on their distance from the cavity’s inner wall (see Near Range, Far Range above). The left edge of the gradient represents the Near Range value, the right the Far Range value. A white color on the gradient means the puffs will remain the same size or luminosity. Black means zero radius or no luminosity, while gray values are intermediate values.
这些梯度控制的半径和亮度的泡芙取决于他们的距离从洞的内壁(见近距离，远距离以上)。渐变的左边缘代表近距离值，右边代表远距离值。梯度上的白色意味着气泡的大小和亮度保持不变。黑色意味着零半径或没有亮度，而灰色值是中间值。
记住:
This effect is based on the cylindrical distance the particles have from the emitter. The left end of the gradient represents the Near Range, the right the Far Range.
这种效果是基于粒子与发射器之间的圆柱距离。渐变的左端代表近距离，右端代表远距离。
Use this effect when simulating heat or fire.
当模拟热或火时使用这个效果。
The cylindrical distance can be seen in the image below. The inner cylinder (blue) represents the Near Range (left end of the gradient) and the outer cylinder represents the Far Range (right end of the gradient).
在下面的图片中可以看到圆柱形的距离。内筒(蓝色)代表近距离(梯度的左端) ，外筒代表远距离(梯度的右端)。
The example below shows the influence of the luminance gradient.
下面的例子显示了亮度梯度的影响。

As you can see, luminance is only generated at the core. All puffs that lie outside of the Far Range do not possess this luminance trait. In addition, the color changes as the particles move away from the core.
正如你所看到的，亮度只在核心处产生。所有位于远距离范围之外的气泡都不具有这种亮度特性。此外，当粒子离开核心时，颜色也会发生变化。
色彩搭配
Taking a glance atWorking with PyroClusterbefore continuing may be helpful at this point.
在继续之前浏览一下使用烟火团可能会有所帮助。
The grayscale gradient controls the color mix based on a particle’s cylindrical distance from an emitter. The color will be mixed between the puff’s color, the color defined in the global settings and the color calculated by the distance gradient. This is one of the most powerful functions PyroCluster has to offer. Each grayscale represents the mix ratio of base color (from the globals page) to the color that is generated as a result of the radial distance effect.
灰度梯度基于粒子与发射器的圆柱距离控制颜色混合。颜色将混合之间的粉扑的颜色，颜色定义在全局设置和颜色计算的距离梯度。这是 PyroCluster 提供的最强大的功能之一。每个灰度表示基本颜色(从全局页面)与径向距离效果生成的颜色的混合比率。
Pure black (RGB 0/0/0) will result in only the base color from the globals page being used to color the puffs. Any color that may result from the radius effect will be ignored.
纯黑色(RGB 0/0/0)将导致只有来自全局页面的基本颜色被用来给泡芙上色。任何可能由半径效果产生的颜色都将被忽略。
Pure white (RGB 255/255/255) will color the puffs using only the color from the radius effect. Any color defined on the preferences page will be ignored.
纯白色(RGB 255/255/255)只使用半径效果的颜色。首选项页面上定义的任何颜色都将被忽略。
Any grayscale values in-between will be a mix of both colors.
介于两者之间的任何灰度值都是两种颜色的混合。
Note: The color mix effect is only influence by the cylindrical distance the particles are from the emitter. This means that the degree of mixing of the base color and distance color is defined by the distance the particles are from the emitter. 注意: 色彩混合效果只受粒子与发射器的圆柱距离的影响。这意味着基色和距离色的混合程度是由粒子到发射器的距离来定义的颜色
With the Color Mix and Color gradients you can control how the color of puffs in the cavity should change. As with the Radius and Luminosity gradients, the left end of the gradient represents the Near Range value, the right end represents the Far Range value.
通过颜色组合和颜色梯度，你可以控制空腔中的气泡的颜色应该如何改变。与半径和亮度梯度一样，渐变的左端代表近距离值，右端代表远距离值。
The color defined by the Color gradient is mixed with the base color of puffs, as defined on the Globals page. The Color Mix gradient controls how these two colors are mixed. White means only the color of the puffs inside the cavity is used, while black means only the base color is used; with gray values, these two colors are mixed.
由 Color 渐变定义的颜色与在 Globals 页面上定义的基本颜色混合。Color Mix 渐变控制这两种颜色的混合方式。白色意味着只使用腔内膨胀物的颜色，而黑色意味着只使用基本颜色; 对于灰色值，这两种颜色混合在一起。
In addition, the Color gradient includes an alpha gradient that enables you to control the opacity of puffs in the cavity.
此外，颜色渐变包括一个阿尔法梯度，使您可以控制不透明的泡芙在空腔。
Although this may sound confusing, the colors will only change when the emitters move from or toward the emitter. Use Near Range and Far Range to define the area in which the color should change.
虽然这可能听起来很混乱，但是只有当发射器从发射器移动或朝向发射器移动时，颜色才会改变。使用“近距离”和“远距离”来定义颜色应该改变的区域。
Note: The 注意:distance gradient 距离梯度 represents the color change of each individual puff based on its cylindrical distance from the emitter. Once this puff nears the emitter (e.g., through gravity or wind) its color will be changed in accordance to the distance it is from the emitter. 表示每个单独的烟团的颜色变化，基于它与发射器的圆柱形距离。一旦这个泡芙靠近发射器(例如，通过重力或风) ，它的颜色将根据它与发射器的距离而改变
As you can see in the example above, the distance gradient can also change the volume’s transparency, depending on the distance it is away from the emitter.
正如您在上面的例子中所看到的，距离渐变也可以改变体积的透明度，这取决于距离发射器的距离。
This is regulated by the Alpha gradient which, for example, lets you transform dark, oily smoke into light, transparent steam.
这是由阿尔法梯度调节，例如，可以让你转换成光，透明蒸汽黑色，油烟。
