Then I setup an alpha channel to mix both using a noise shader.
然后我建立一个alpha通道，用noiseshader将两种材质混合。
First of all, you're probably wondering about the impostor's alpha channel.
首先，你可能对视点替用特效的阿尔法通道感到疑惑。
The alpha channel of this texture is used as a mask that determines how bright the light is at different places.
这个纹理的阿尔法(alpha)通道作为一个遮罩，使光线在不同的地方有不同的亮度。
With PNG-compressed images, you do not provide the mask at all; the mask is derived from the alpha channel on the fly.
用了PNG格式的图像，你不再需要提供mask了。 mask自然而然的由PNG的透明通道提供。
A new natural image algorithm was put forward based on alpha channel with a good result as well as a rapid speed.
在以前算法的基础上，提出了一种相对快速且效果也较好的基于透明度的景物提取算法。
Google also mentioned they work on adding alpha channel support, more speed improvements and a complete metadata specification.
Google提及他们正在着手增加Alpha通道支持，进一步提升速度，以及加入完整的元数据规范。
After the information is embedded in the image, the resulting data is output as a PNG file, with alpha channel information used to carry the data.
在图片中嵌入信息后，得到的数据可以输出为一个PNG文件，使用alpha通道信息来携带数据。
Each component has its own expansion of the painting attributes, such as color gradual expansion frame, the alpha channel, real-time shadows.
每个控件都有自己扩展的绘画属性，诸如渐进色，扩展边框，alpha通道，实时阴影。
We couldn't manage this aspect during post production, because there would have been lot of problems with alpha channel on the leaves of the background trees.
在后期制作中我们不能达到这一点，因为在背景树的树叶上阿尔法通道会出现很多问题。
“And then here at the end, here’s me saying, ‘Oh, and here’s a new user interface. It’s translucent, there’s real-time animation, and a full alpha channel, ’” Ratzlaff recalled.
最后轮到我发言了，‘现在我们来看看新的用户界面，它是半透明的，有实时动画和一个完整的alpha通道’“Ratzlaff回忆道，”但现场只有笑声，因为根本不肯能再去重做用户界面。
In general, trade software also allows for defining certain transition color range. For pixel within the range, its Alpha Channel is set between 0 and 1, i. e., translucent.
专业软件一般还允许设定一定的过渡颜色范围，在这个范围之内的像素，其Alpha通道设为0到1之间，即半透明。
Of course you can do better with the corresponding slider, but with this technique we can change every Map To channel - not just Alpha.
当然你可以使用相关的滑块作的更好，但使用这个技术我们可以修改通道的每个映射-而不仅仅是Alpha。
