Generator Device - Voronoi Noise 生成器设备 - 泰森多边形噪声


Voronoi noise implements a cellular texture basis function as described by Steven Worley. Voronoi noise has sharp discontinuities (ridges), and can form the basis for some very interesting terrain effects.


Feature Size Controls the density of features of the terrain.
It roughly corresponds to the distance between major peaks or valleys. Low values produce quickly changing terrain, suitable for hills or lumps, while middle values are ideal for mountains. Large values allow continents and other shapes that are created on a massive scale.
尺寸特征 控制地形的特点的密度.
它大致相当于主要峰或谷之间的距离。 低值将产生迅速变化的地形,适合丘陵或肿块, 虽然中间值,非常适合山区。 大的值允许大陆和其他大规模创建的形状。
Style The Voronoi styles are difficult to describe. Each produces a different character of output ridges; experimentation is really the only guide to what style may look good in what circumstances.
样式 泰森多边形风格是难以描述的。每个生成不同的输出脊的字符;实验是唯一在什么情况下看起来很不错的风格指南。
Fn style: Uses the distance to the n-th closest point to create the texture
Fn 样式: 使用最近点距离来创建纹理
Fm - Fn style: Equivalent to subtracting the Fn texture from the Fm texture
Fm - Fn 样式: 相当于减去Fn纹理从调频纹理
Fn Cells: Creates single-value cells identifying where a given feature point is used.
Fn 单元: 使用给定的特征点的识别创建单值的单元格
Distance Function How the device measures distance to the nearest point.
距离函数 设备如何测量距离最近的点。
Euclidean: Distances are measured "normally".
欧氏距离 距离测量"normally".
Manhattan: Distances are measured at right angles; so called because it is equivalent to how you would specify distances in a large city, by “X blocks up and Y blocks over”.
曼哈顿区: 直角的距离测量;如此称呼是因为它相当于你将如何在大城市中指定的距离,"X街区和Y街区"。
Alternatives #1 and #2: Distances measured using special metrics; the effect created is better visualized rather than described.
方案 #1 and #2: 测量的距离使用特殊指标;所产生的效果是较好的可视化,而不是描述.
Random Seed The value used to begin, or “seed”, the random number generator for this device. Different seed values will produce similar features but in completely different locations.
随机速度 该值用于开始或"seed",该设备的随机数发生器。不同的种子值会产生类似的功能,但在完全不同的位置。
Enable Distortion Input When checked, an optional input is revealed on the Voronoi device that accepts a heightfield. The distortion input allows you to shift the coordinates that are fed into the Perlin Noise device in a certain direction; this allows some very interesting effects to be created.
启用变形输入 在选中时,一个可选的输入显示在接受高度场的Voronoi设备。变形输入允许你改变坐标,它被输入的柏林噪声设备在某一方向;这允许创建一些非常有趣的效果。
Phase Distortion
Strength: The amount that the noise function should be shifted in a given direction. This controls the strength of the effect; low values provide only a subtle effect, while large values can be quite dramatic and wild depending on the heightfields.
强度: 应转移到噪声函数在给定方向。这种控制作用的力量;低值仅提供一个微妙的影响,而颇具戏剧性的和野生的值取决于高度场。
Direction: The direction in which the coordinates should be shifted. Specified by an angle, where 0 is to the left, 90 is down, 180 is to the right, and so on.
方向: 方向坐标将被转移。指定一个角度,其中0是在左边,下降90,180号是在右边,等等
