Generators

发电机

On the Generators menu, you will find some of Cinema 4D’s most powerful modeling objects, including Extrude (for 3D logos, etc.) and Subdivision Surfaces (for any type of model, especially smooth shapes, such as characters). 在 Generators 菜单上，你会发现一些 Cinema 4D 最强大的建模对象，包括挤压(对于3D logo 等)和细分曲面(对于任何类型的模型，特别是光滑的形状，如人物)

Generator objects are interactive, which means they use other objects to generate their surfaces. Generators enable you to create surfaces quickly and easily using simple curves or objects. For example, to create a wine bottle you might draw half the bottle’s outline as a spline and make this spline a child of a Lathe object. The spline will then be revolved through 360˚ to generate the bottle.

生成器对象是交互式的，这意味着它们使用其他对象来生成它们的表面。生成器使您能够快速、方便地使用简单的曲线或对象创建表面。例如，要创建一个酒瓶，你可以绘制半个酒瓶的轮廓作为样条，并使这条样条成为一个车床对象的子对象。然后将样条旋转360以生成瓶子。

In addition to helping you model quickly, Generators are faster and easier to edit than comparable polygon models that have thousands of points. For example, suppose you want to change the shape of a wine bottle. In the viewport, drag the spline’s points to form the new outline. The bottle updates in real-time as you drag the points, and in just a few seconds you have made the changes.

除了帮助您快速建模，生成器更快，更容易编辑比可比的多边形模型，有数千个点。例如，假设你想改变一个酒瓶的形状。在视口中，拖动样条的点来形成新的轮廓。瓶子实时更新，因为你拖动点，并在短短几秒钟，你已经作出了改变。

Although modeling with Generators is generally more powerful than polygon modeling, there are still occasions when polygons are useful. For example, you must work with polygons if you want to use polygon tools such as the Magnet tool. Therefore, before you can use one of these tools on a Generator object, you must first convert the Generator to polygons. To do this, select the Generator object and choose Mesh | Conversion | Make Editable. Keep in mind that the conversion is one-way only — you cannot convert the polygons back to Generators.

虽然生成器建模通常比多边形建模更强大，但仍然有多边形有用的时候。例如，如果要使用磁铁工具等多边形工具，则必须使用多边形。因此，在对 Generator 对象使用这些工具之一之前，必须首先将 Generator 转换为多边形。为此，选择生成器对象并选择 Mesh | Conversion | Make Editable。记住，转换只是单向的ーー你不能将多边形转换回生成器。

Generator Objects and Hierarchies

生成器对象和层次结构

The Subdivision Surface object will affect only its first child object. The entire hierarchy of that child object is affected, unless a Stop tag is added.

细分曲面对象将只影响它的第一个子对象。除非添加 Stop 标记，否则该子对象的整个层次结构都会受到影响。

The remaining Generator objects will take only the splines in the top-most hierarchy into account. Further, the Generators will only use as many splines as is necessary to generate the object.

其余的 Generator 对象将只考虑最顶层层次结构中的样条。此外，生成器将只使用生成对象所需的多个样条。
