Our house will be pretty simple - four walls and a roof, but we'll get to know how to create vertices and faces, and how to form surfaces from faces' groups.
我们的房子非常简单——四面墙、一个房顶，但是我们将学会如何建立多个顶点和多个面，并且从多个面的组里面构建表面。
You should create vertices in order to construct an object. To understand which vertices our object will have, lets draw house projections on a planes XY and YZ.
你应该通过建立多个顶点来构建对象。理解我们对象里存在的顶点，让我们先在XY、YZ平面画一下房子的预测。
Buckyballs, for instance, have a unique spherical structure of atomic bonds that create a hexagon-pentagon structure (like that of a soccer ball) with atoms residing at the vertices.
例如，布基球的原子键是一种独特的球面结构，球面中有六边形也有五边形(就和足球一样)，碳原子位于顶点处。
