Seed Values

种子价值

At various locations in Cinema 4D where random values are dispersed, you will find a Seed setting. These values make "varied" random sequences available. Often, a series of random numbers is required, which are then fed internally to functions. This can, for example, be applied to a Landscape object or Noise shader:

在C4D院的不同位置，随机值分散，你会发现一个种子设置。这些值使得“各种”随机序列成为可能。通常，需要一系列随机数，然后将其内部提供给函数。例如，这可以应用于横向对象或噪音着色器:

What’s special about this seed value is that the numbers that are generated are not entirely random but start from the seed value, which means that the same seed value (within a given function) will produce the same, reproducible random sequences. For example a Seed value of 638 for a Landscape object will produce the exact same geometry on any computer or program version. There is no correlation between small seed value differences and their results: values of 638 and 639 will produce entirely different random sequences. Almost all Seed value settings in Cinema 4D work according to this principle.

这个种子值的特别之处在于，生成的数字并不完全是随机的，而是从种子值开始，这意味着相同的种子值(在给定的函数中)将生成相同的、可重复的随机序列。例如，一个景观对象的种子值为638将产生完全相同的几何形状在任何计算机或程序版本。小的种子值差异和它们的结果之间没有相关性: 638和639的值将产生完全不同的随机序列。几乎所有的C4D的种子值设置都是根据这个原则工作的。

There are, however, Seed values (e.g., for the Random Effector) for which the aforementioned small seed value differences do make a difference. If a decimal place is modified (e.g., from 683.2 to 638.3), the ramdom sequences will be similar.

但是，对于某些种子值(例如，对于随机效果器) ，前面提到的小种子值差异确实会产生差异。如果一个小数位被修改(例如，从683.2到638.3) ，ramdom 序列将是类似的。
