As the name suggest, polygonal modeling involves constructing the models out of polygons. Strictly, software packages works only with triangles. Blender could show you quads and some software packages could even let you work with polygons with more than 4 sides (n-gons) but these packages work internally only with triangles. These triangles are hidden so that you could concentrate more on modeling.
::像名字所暗示的那样,多边形建模涉及构建模型的多边形.严格来说,软件包只能使用三角形. 混合剂可以显示你四边形,一些软件包甚至可以让你与多边形工作有超过4个边 (n-gons),但这些软件包内部只能使用三角形. 这些三角形是隐藏的,这样你就可以更多地专注于建模.

While different modelers works differently, they would still follow certain workflows (some call this techniques). These are familiarly called box modeling and polygon-by-polygon modeling (poly-by-poly modeling).
::虽然不同模型设计者的工作方式不同,但它们仍然遵循某些工作流程 (有些人称之为技术).这些通常被称为盒式模型和多边形对多边形模型 (多边形对多边形模型).

Box modeling  is a top-down approach where modelers start with a primitive (usually a cube (box), hence the box in box modeling). Then from this primitive, the model's form is build up where details are gradually added.
::盒式建模是一种自上而下的方法,模型设计者从一个原始模型开始 (通常是一个立方体 (盒子),因此在盒式建模中使用的是盒子).然后从这个原始模型中构建模型的形式,逐渐添加细节.

Poly-by-poly modeling  is almost the opposite of box modeling. It is the bottom-up approach where modelers start with a plane or even a vertex. Using extrusion and other tools, more geometries are added. Polygon by polygon the model is gradually build.
::多重模拟几乎与盒式模拟相反.这是自下而上的方法,模拟者从平面甚至顶点开始.使用挤出和其他工具,添加更多的几何形状.多边形逐个模拟逐渐构建.

Neither of the two is better than the other but there are instances where one workflow lends much better to the situation. One typical advantage of box modeling is that at early stage, you are able to conceive first the form (the whole) of the model and is better equipped to do general corrections without bothering yet with the details. Poly-by-poly otherwise give you more control on the geometry and is much more easier to use in modeling complex forms like the human ear. Complications do arise when working with the two. In box modeling, it is typically difficult to manage the geometry when adding details. Experience is necessary so as not to create a mess. Poly-by-poly modeling otherwise has its own quirks. Since you are going detail by detail, it is easy to make a mess with the models form (i.e. wrong proportions).
::两种方法都不比对方好,但有时一种工作流程对情况更好.盒式建模的一个典型优点是,在早期,您可以首先构想出模型的形式 (整体),并且更好地进行一般的校正,而无需费心细节.多重复合方式 (poly-by-poly) 否则可以让您对几何学有更大的控制,并且在建模人类耳朵等复杂的形式时更容易使用.在使用这两种方法时确实会出现复杂性.在盒式建模中,在添加细节时通常很难管理几何学.经验是必要的,以免造成混乱.多重复合方式建模否则有其特点.由于您是细节的,因此很容易在模型中以错误的形式 (即比例) 进行

While the two are opposites, they compliment each other beautifully. Most modelers would combine the two workflows in a variety of proportions, combining the strength of each. For example one might model a human body using box modeling while the head and the ears are done using poly-by-poly modeling.
::虽然这两种工作流是对立的,但它们彼此相辅相成.大多数建模师会将这两种工作流结合在各种比例中,结合每一种力量.例如,一个人可能使用盒建模来建模人体,而头部和耳朵则使用多重建模.

Blocking with primitives  is added to enrich approaches is modeling. It is basically box modeling in conjunction with divide-and-conquer approach. Different parts are modeled separately with their own primitives and later attached with the others to form the whole.
::模拟方法是通过原始的阻断来丰富.它基本上是与分为两者的方法结合的盒式模拟.不同的部分是用自己的原始单独模拟的,然后与其他部分连接在一起形成整体.
