Instance color 【实例颜色】

Instance Color

The Instance Color texture is used to hold an image and prepares each pixel of the image to be mapped to geometric instance IDs. The c4doctane plugin is able to generate instances of an object and can also assign an ID to each of the instances generated such that number of instances results in a grid instance IDs. Colors can then be assigned via texture to each instance ID, in this case with an image in the Instance Color texture, matching the IDs with pixels of the image starting at the bottom left in row major order up to the top right.
Instance Color 纹理用于保存图像，并准备将图像的每个像素映射到几何实例 id。4doctane 插件可以生成一个对象的实例，也可以为生成的每个实例分配一个 ID，这样数量就可以生成一个网格实例 ID。然后可以通过纹理为每个实例 ID 分配颜色，在这种情况下，使用 Instance Color 纹理中的图像，将 ID 与图像的像素匹配，从左下角开始，按主序从右上角开始。

Instance Color 有许多用途，这些用途将在下面的迷你教程中描述。当您按照教程操作时，您可以在现场检查它们。您可以从这个链接下载教程中描述的所有场景

INSTANCE COLOR FROM FILE 实例颜色来自文件

In this first mini tutorial, we will describe how to apply a small texture map on to a collection of clones.
1- First create a cylinder object and change its properties as shown in the picture.
在这第一个小教程中，我们将描述如何将一个小的纹理贴图应用到克隆的集合中。
1-首先创建一个柱面对象并更改其属性，如图所示。

2- Then create a Cloner object and assign the cylinder object to the Cloner. Change the cloner settings as shown in the image below.
2-然后创建一个 Cloner 对象，并将柱面对象分配给 Cloner。更改克隆器设置，如下图所示。

3- Next is the Material and Instance Color Setup. First create the Diffuse Material. Then open the Node Editor and drag and drop the material you created into the Node editor window. Drag the Instance Color directly to the node editor from the menu on the left. Now, when Instance Color Node is selected, connect the output pin to the input pin of the Diffuse channel of Material. Now select any image file with 10x10 pixel size from the menu on the right and load it. After the Material Setup, Assign it to Cloner Object. In the picture below you can see the material and Instance Color setup.
3-下一步是材质和实例颜色设置。首先创建漫反射材质。然后打开“节点编辑器”，将创建的材质拖放到“节点编辑器”窗口中。从左侧的菜单中直接将 Instance Color 拖动到节点编辑器。现在，当选择 Instance Color Node 时，将输出引脚连接到材质扩散通道的输入引脚。现在从右边的菜单中选择任何10x10像素大小的图像文件并加载它。材质设置完成后，将其分配给 Cloner 对象。在下面的图片中，你可以看到材质和实例颜色设置。

4- You should get a result similar to the following image. As you can see, each pixel value of our 10x10 pixel sized image created Instance Color for our 10x10 grid cylinders in Cloner. The Instance IDs of 100 cylinders in Cloner were automatically generated, similar to the Shader Effector. This works best with smaller image files. Larger sizes may crash Cinema 4D.
4-你应该得到一个类似于下图的结果。正如你所看到的，我们的10x10像素大小的图像的每个像素值为我们的10x10网格柱面创建了 Instance Color。实例 id 的100个气缸在克隆人是自动生成的，类似于着色效应器。这对于小图像文件效果最好。更大的尺寸可能会使4d 电影院崩溃。

INSTANCE COLOR FROM VERTEX COLOR

顶点颜色实例颜色
In this example we will describe how Instance Color is made from a Vertex Color.
1- First create a cylinder object and change its properties as shown in the picture.
在这个例子中，我们将描述实例颜色是如何从一个顶点颜色。
1-首先创建一个柱面对象并更改其属性，如图所示。

2- Then create a “Plane” object and change its settings shown in the image below. After entering the settings, make it editable (Press C).
2-然后创建一个“平面”对象，并改变其设置如下图所示。输入设置后，使其可编辑(按 c)。

3- Now we will paint the vertices of the Plane object. Select Plane Object and then select the Point Mode.
Press Shift + C and select Paint Tool from the command menu.
3-现在我们将绘制平面物体的顶点。选择平面物体，然后选择点模式。
按下 Shift + c 并从命令菜单中选择画图工具。

4- Paint the vertex in any color and shape using the Paint menu. Do not forget to select “Vertex Color (RGB)” from the paint menu. Once the painting is finished, the “Vertex Color Tag” will be automatically created in the Object Manager, next to the plane object. You will then use this Tag as Instance Color.
4-使用画图菜单以任何颜色和形状绘制顶点。不要忘记从绘图菜单中选择“顶点颜色(RGB)”。一旦绘制完成，“顶点颜色标签”将自动创建在对象管理器，旁边的平面对象。然后您将使用此标记作为实例颜色。

5- Create a Cloner object and assign the cylinder object to the Cloner. We also need to define Plane, which we just created, as the object to which the cylinder clones will distribute. See the image below for settings.
5-创建一个 Cloner 对象，并将柱面对象分配给 Cloner。我们还需要将我们刚刚创建的 Plane 定义为柱面克隆将分布到的对象。参见下面的图片进行设置。

6- Next is the Material and Instance Color Setup. First create the Diffuse Material. Then open the Node Editor and drag and drop the material you created into the Node editor window. Drag the Instance Color directly to the node editor from the menu on the left. Now, when Instance Color Node is selected, connect the output pin to the input pin of the Diffuse channel of Material. Now it’s time to set the Vertex tag. When Instance Color Node is selected, select Particle as Source from the menu on the right. In the Color Source section, drag and drop the Vertex Color tag of the Plane object. After the Material Setup, Assign it to Cloner Object. In the picture below you can see the material and Instance Color setup.
6-下一步是材质和实例颜色设置。首先创建漫反射材质。然后打开“节点编辑器”，将创建的材质拖放到“节点编辑器”窗口中。从左侧的菜单中直接将 Instance Color 拖动到节点编辑器。现在，当选择 Instance Color Node 时，将输出引脚连接到材质扩散通道的输入引脚。现在是设置 Vertex 标签的时候了。当选择“实例颜色节点”时，从右侧菜单中选择“粒子作为源”。在“颜色源”部分，拖放“平面”对象的“顶点颜色”标记。材质设置完成后，将其分配给 Cloner 对象。在下面的图片中，你可以看到材质和实例颜色设置。

7- You should get a result similar to the following image. As you can see, the cylindrical objects were colored by the vertex color tag of the plane. Although it is not a very practical method, at least it gives you more control and flexibility. You can also work with more vertex counts. Remember that too many vertices will increase your cloner objects count and the system performance will diminish.
7-你应该得到一个类似于下图的结果。正如你所看到的，圆柱形物体是由平面的顶点颜色标签着色的。虽然这不是一个非常实用的方法，但至少它给了您更多的控制和灵活性。你也可以使用更多的顶点数。记住，太多的顶点会增加 cloner 对象的数量，系统性能会降低。
