Angle Limit
Phong Angle[0..180°]

角度限制/角度[0.180 ° ]

Use this setting to define the angle to which two neighboring surfaces should be rounded. To do so, activate the Angle Limit option and enter the desired angle here.

使用此设置可定义两个相邻表面应该圆角的角度。要做到这一点，激活角度限制选项，并输入所需的角度在这里。

The effect of this function is shown in the example below. A simple cylinder was used as a test object. The image at the left Phong Angle was applied without Angle Limit, in the center Angle Limit was set to 89.5° and the cylinder at the right has no Phong Angle applied.

这个函数的效果如下面的例子所示。用一个简单的圆柱体作为测试对象。左边 Phong Angle 的图像没有角度限制，中心角度限制设置为89.5 ° ，右边的圆柱体没有角度限制。

When calculating smoothed objects, Cinema 4D always assumes the polygons (and their Normals vectors) are oriented uniformly. If they are not, shadow anomalies can occur when the image is rendered. All primitives, though, have a uniform orientation.

在计算平滑对象时，Cinema 4D 总是假定多边形(及其法向量)是均匀排列的。如果他们不是，阴影异常可能发生时，图像渲染。然而，所有的原语都有一个统一的方向。

Use Edge Breaks

使用边缘休息

When in edge mode, Cinema 4D allows you to break the Phong shading along edges using the Break Phong Shading command (Mesh menu).

当在边缘模式，C4D 允许你打破 Phong 阴影沿边缘使用打破 Phong 阴影命令(网格菜单)。

The edge breaks in red and the rendered result. 边缘以红色显示，并显示结果

When breaking individual edges, the effect will only occur if the end points of the edge are surrounded by connected polygons (Break Phong Shading – Mesh menu). In the following illustration, the effect of breaking will be visible for edge A, but not for edge B.

当破坏单个边缘时，只有当边缘的端点被连接的多边形包围时才会产生效果(破坏 Phong 着色-网格菜单)。在下图中，边 a 可以看到断裂的影响，而边 b 则看不到。

Broken Phong edges only work when the Phong tag’s Angle Limit option is enabled. If you don’t want to use an angle, set Angle Limit to 180 (this corresponds to no angle limit). 破损的 Phong 边缘只有当 Phong 标签的角度限制选项被启用时才能工作。如果你不想使用一个角度，设置角度极限为180(这相当于没有角度极限)

You can enable or disable the effect via the Use Edge Breaks option.

您可以通过“使用边缘分隔符”选项启用或禁用该效果。

The following types of Generators object make use of these new Phong features: Extrude, Lathe and Sweep. To see the difference, select the Generator object’s Phong tag and in the Attribute Manager, disable the Use Edge Breaks option. Provided the option is enabled, the edges will be sharp.

以下类型的生成器对象利用这些新的 Phong 特性: 挤压，车床和扫描。要查看差异，选择 Generator 对象的 Phong 标记，在 Attribute Manager 中，禁用 Use Edge Breaks 选项。如果选项启用，边缘将是锐利的。

Left: Use Edge Breaks disabled; Right: Use Edge Breaks enabled 左边: 使用边缘休息被禁用; 右边: 使用边缘休息启用

Create Normal Tag

创建普通标签

Click on this button if you want to create a Normal tag from the Vertex Normals currently defined by the Phong tag (see also Normal tag).

如果您想要从 Phong 标记当前定义的顶点法线创建一个 Normal 标记，请单击此按钮。

If a Normal tag already exists, this button will be grayed out; it will also be grayed out if the Phong tag is assigned to a primitive or a Generator.

如果 Normal 标记已经存在，这个按钮将变成灰色; 如果 Phong 标记被分配给一个原语或 Generator，它也将变成灰色。
