Color

颜色

Sets the base diffuse color of the surface.

设置表面的基本漫反射颜色。

Algorithm

算法

Specifies which illumination model Lumas will use. The drop-down list provides for two choices: Internal, which is the standard Lambertian model, and Oren Nayar, which provides for a roughness variable allowing the user to go from simple surfaces (0 Roughness, identical to Lambertian), to complex rough surface (1+ Roughness, which provides a matt surface, such as linen or dirt).

指定将使用哪种照明模型。下拉列表提供了两个选择: 内部，这是标准的 Lambertian 模型，和 Oren Nayar，它提供了一个粗糙度变量，允许用户从简单的表面(0粗糙度，相同于 Lambertian) ，到复杂的粗糙表面(1 + 糙度，提供亚光表面，如亚麻布或灰尘)。

Roughness[0..200%]

粗糙度[0. . 200% ]

Dictates how rough the Oren Nayar illumination model will be. Zero is no roughness while 100% or greater is very rough. Experimentation is required to fully understand this parameter. This option is only available if Oren Nayar is selected in the Algorithm drop-down list.

指出奥伦 · 纳亚尔的照明模型将会有多么粗糙。零是没有粗糙度，而100% 或更大是非常粗糙。要充分理解这个参数，需要进行实验。此选项仅在 Oren Nayar 在“算法”下拉列表中被选中时可用。

Illumination[0..1000%]

照明[0. . 1000% ]

Scales the Color to produce attenuation in the illumination of the surface (this simply means it makes the color darker when the value is close to zero and brighter when the value is closer to 100% or above).

缩放颜色以产生表面光照衰减(这只是意味着当颜色接近于零时颜色变暗，当颜色接近100% 或以上时颜色变亮)。

If you are using the Oren Nayar illumination algorithm, you may want to bump up the illumination by about 10% to 20% because it renders darker usually. Appropriate values are between 0% to 200%.

如果你正在使用 Oren Nayar 照明算法，你可能会想要把照明提高10% 到20% ，因为它通常呈现较暗的效果。适当的值在0% 到200% 之间。

Contrast[-1000..1000%]

对比度[-1000. . 1000% ]

Provides contrast for the result of the Color. Zero causes no effect, 0% - 100% causes standard contrast, above 100% causes a wrap contrast (the values that go above 100% wrap around to 0% again, used to create the Candy materials), negative values provide an inverse contrast that simulates materials that seem luminescent, such as silver. Appropriate values are -500% to 500%.

为 Color 的结果提供对比度。零不会产生影响，0%-100% 会产生标准对比度，超过100% 会产生环形对比度(超过100% 环形对比度的值再次变为0% ，用于创建糖果材质) ，负值提供一个反向对比度，模拟发光材质，如银。适当的数值为 -500% 至500% 。
