在这些笔记中，我们调查了一些用于3D场景的非真实感渲染的基本工具。我们将主要关注检测对象形状的轮廓：轮廓，边界和折痕。（阴影和阴影对于传达形状也非常重要，在课程笔记的其他地方进行了讨论。）本节中的算法可以分为在图像空间（2D）中操作的算法和在世界空间（3D）中操作的算法。
In these notes, we survey some of the basic tools used for non-photorealistic rendering of 3D scenes. We will primarily focus on detecting outlines of object shape: silhouettes, boundaries, and creases. (Hatching and shading, which are also very important for communicating shape, are discussed elsewhere in the course notes.) The algorithms in this section can be divided into algorithms that operate in the image space (2D), and algorithms that operate in world space (3D).
