The Silhouette Edge
Stencil shadowing is about finding a silhouette of the mesh, and projecting it away to form a volume. What this means is that there is a definite boundary on the shadow caster between light and shadow; a set of edges where where the triangle on one side is facing toward the light, and one is facing away. This produces a sharp edge around the mesh as the transition occurs. Provided there is little or no other light in the scene, and the mesh has smooth normals to produce a gradual light change in its underlying shading, the silhouette edge can be hidden - this works better the higher the tesselation of the mesh. However, if the scene includes ambient light, then the difference is far more marked. This is especially true when using 7.3 Modulative Shadows, because the light contribution of each shadowed area is not taken into account by this simplified approach, and so using 2 or more lights in a scene using modulative stencil shadows is not advisable; the silhouette edges will be very marked. Additive lights do not suffer from this as badly because each light is masked individually, meaning that it is only ambient light which can show up the silhouette edges.

轮廓边界

模板遮蔽是要找到mesh网格的边界轮廓，并将它投影形成一定体积。意思就是，在光和阴影之间有一个产生阴影物体的明确边界。其中一面三角形的边面光，而另一面背光。这样当发生转变时，就在mesh网格周围形成了一个清晰的边界。当场景中提供的光很少或者根本没有光时，mesh网格有平滑的法线用以生成其下渲染的渐变光，轮廓边界可以被隐藏——mesh网格数越高，其工作效果越好。但是，如果场景中包含环境光，那么区别则相当明显。当使用7.3 Modulative Shadows时尤为突出，因为每个阴影区域的光照贡献并为纳入这个简化方法的计算之内，而且在使用调制模板阴影的场景中使用2个或者更多的光是不明智的；轮廓边界将会非常明显。附加的光不会因此而受到影响，因为每一个光都是被独立遮蔽的，也就是说，能够显示出轮廓边界的只有那唯一的环境光。

orz谢谢，翻译到这一段怎么也搞不清楚了。

呵呵，其实直译译不出，可以意译一下。不要把它看作是外语，理解意思，就好了。
