The next step is modeling, where animators create a wireframe of points and lines that define a character's shape.

下一步是建模，动画师在这时会创建一个由点和线组成的框架，定义角色形状。

Wireframe rendering is cool and all – sorta retro – but of course 3D graphics can also be filled.

线框渲染很酷而且很复古——当然也可以填充 3D 图形。

And get this, with this piece of work, we can have a low-fidelity wireframe version printed immediately as we make changes within the modeling software.

注意，有了我们今天讲的这篇论文，我们就能获得一个低精度的线框版模型，在建模的同时立即将其打印出来。

We could redesign this jacket to have a hidden wireframe, kind of like the skeleton of a fish, that holds all important items together.

我们可以重新设计这件夹克， 让它有一个隐藏的线框，有点像鱼的骨架， 把所有重要的东西都放在一起。

Also, the handle of the teapot here collides with the body — because of the limitations of wireframe modeling, such cases have to be detected and omitted.

此外，像这里，茶壶的把手处和茶壶杯体相交了——因为线框建模的局限性，这种情形必须被检测出来而且去掉。
