To set up projections, select Tools -> Projection Setup in the SpiderVision Setup window menu:要设置投影，请在SpiderVision Setup窗口菜单中选择Tools -> Projection Setup:

The Projection Setup window will open. This window makes it possible to:Projection Setup窗口将打开。此窗口提供以下工具:

Interface界面

The Warp tab allows you to set up geometry correction for your projections. Areas where geometry correction is required include:Warp选项卡允许您为投影设置几何校准。需要几何校准的区域包括:

• Advanced off-axis correction where projector placement is awkward and needs an advanced mapping over the keystone function in a projector先进的离轴校准，其中投影机的放置是不方便的，需要一个先进的映射在投影机的梯形功能
• Non-planar screens such a curved screens and hemispherical domes非平面屏幕，如弧形屏幕和半球形圆顶
• Projecting one image from one projector onto more than one surface将一个图像从一个投影仪投射到多个表面上
• Unusual projection applications onto custom designed screens不寻常的投影应用到定制设计的屏幕上

Warping is performed by modifying the displayed grid in the visual editor. Set up warping for the selected projection using control points and yellow handles. These handles are displayed for each selected control point depending on its type.翘曲是通过修改可视化编辑器中显示的网格来执行的。使用控制点和黄色句柄为选定投影设置翘曲。根据其类型，将为每个选定的控制点显示这些控制柄。

注意

Points are always moved in the screen-space coordinates regardless of image orientation (whether it is flipped or not), this means if you press left arrow, the point always goes left.无论图像方向如何（无论是否翻转），点总是在屏幕空间坐标中移动，这意味着如果按左箭头，点总是向左移动。

The possible ways of controlling the point positions are listed here.这里列出了控制点位置的可能方法。

You can see an example of a warped grid and a corresponding projection image below.您可以在下面看到翘曲网格和相应投影图像的示例。

Warped grid翘曲的网格

Warped image翘曲的图像

In addition to the common settings, the following options specific for the Warp tab are available:除了通用设置之外，Warp选项卡还可以使用以下选项：

Reset Warp Grid	Resets the warp grid to the default state.将翘曲网格重置为默认状态。
Canvas	Configure the canvas for the selected projection: enable vertical and horizontal flipping.为所选投影配置基础：启用垂直和水平翻转。

The Color Correction tab allows you to correct color intensity, as well as to adjust color balance for the selected projection.Color Correction选项卡允许您校准颜色强度，以及调整所选投影的颜色平衡。

Brightness	Per-channel color multiplier to control the intensity of:每通道颜色倍增器来控制的强度: 红色 绿色 蓝色 同时这三种颜色 Brightness for the red channel = 2红色通道的亮度=2
Contrast	Settings that allow you to adjust the color balance per channel (as well as for all channels at once):允许您调整每个通道的色彩平衡（以及一次调整所有通道的色彩平衡）的设置: Positive values are added to the color values on the screen.正值被添加到屏幕上的颜色值。 Negative values are subtracted from color values on the screen.负值从屏幕上的颜色值中减去。 Contrast for the red channel = -0.1红色通道的对比度=-0.1
Brightness (corners)	Settings to adjust brightness compensation for each of the projection's corners individually.设置以单独调整每个投影角的亮度补偿。

The Blend Zones tab allows you to configure blending in the selected area.Blend Zones选项卡允许您在选定区域配置混合。

The screen-space blend area is not affected by warping.屏幕空间混合区域不受翘曲的影响。

To start creating the blending area, click the Add button, and in the grid, click to define one side of the area, then click to define the other side — the green line will appear. The third click shows the blending direction.要开始创建混合区域，请单击Add并在网格中，单击以定义区域的一侧，然后单击以定义另一侧-绿线将出现。第三次点击显示混合方向。

Defining a screen-space blending area定义屏幕空间混合区域

The blended area混合区

The area of the screen-space blend area is divided into two parts: the part between the blue and green lines is a solid-black area (i.e. the projected image is not displayed at all), and the part between the green and red lines is a gradient area (i.e. the projected image gradually becomes transparent).屏幕空间混合区域的区域分为两部分:蓝绿线之间的部分为纯黑色区域(即投影图像根本不显示)，绿红线之间的部分为渐变区域(即投影图像逐渐透明)。

In plain words, if you have two projectors, the green line of the blend zone in one projection should coincide with the red line of the blend zone in the other projection. For more than two projectors, the area between blue and green lines is used.简而言之，如果您有两个投影机，则一个投影中的混合区域的绿线应与另一个投影中的混合区域的红线重合。对于两台以上的投影仪，使用蓝线和绿线之间的区域。

By default, each of these lines has two points marking the line limits. Using Resolution, you can increase the number of points along each line to adjust it as required by moving the points. Multi-selection of points is available.默认情况下，每条线都有两个点标记线的限制。使用Resolution参数，您可以增加每条线的点数，以便通过移动点来根据需要进行调整。点的多选择是可用的。

In addition to the common settings, the following options specific for the Blend Zones tab are available:除了通用设置之外，Blend Zones选项卡还可以使用以下选项：

Add	Adds a blend zone 添加混合区域。
Remove	Deletes the selected blend zone.删除选定的混合区域。
Apply	Enables or disables application of the selected blend zone to the rendered image.启用或禁用将选定的混合区域应用于渲染图像。
Link to Projection	Allows adjusting Alpha, Contrast, and Gamma for two blends simultaneously for better neighboring of two projections. If toggled on, select the projection and the blend area from the drop-down lists and adjust the necessary parameters.允许同时调整两个混合的Alpha, Contrast和Gamma，以更好地相邻两个投影。如果启用，从下拉列表中选择投影和混合区域，并调整必要的参数。
Name	Blend area name in the Screen-Space Blending list.Screen-Space Blending列表中的混合区域名称。
Alpha	Transparency of the whole blended area.整个混合区域的透明度。
Contrast	Contrast of the gradient part of the blended area.混合区域的梯度部分的对比度。
Gamma	Gamma correction value for the blend zone.伽马校准值。

The Masks tab allows using masks to cut out certain areas of the selected projection. Masks选项卡允许使用蒙版剪切选定投影的某些区域。

To create a mask, click Add and ensure that the Creation Mode button is enabled. Then create at least three points on the grid by clicking in the required place. The corresponding area of the projection will be cut out. The list of masks for the current projection is displayed under the grid. You can add new masks and remove existing ones using the corresponding buttons.要创建蒙版，请单击Add并确保启用了Creation Mode按钮。然后通过单击所需的位置在网格上创建至少三个点。投影的相应区域将被切出。当前投影的蒙版列表显示在网格下。您可以使用相应的按钮添加新的蒙版并删除现有的蒙版。

To add new points to the mask selected in the list, ensure that the Creation Mode button is enabled. Then you can add new points by clicking within the grid area. To insert a new point into an existing mask, select the point next to which a new point is to be added, and click to insert a new one. You can drag an existing point to move it. To remove a point, right-click it.要向列表中选择的蒙版添加新点，请确保启用了Creation Mode按钮。然后，您可以通过单击网格区域内添加新点。要将新点插入到现有蒙版中，请选择要添加新点的点旁边的点，然后单击以插入新点。您可以拖动现有点来移动它。要删除点，请右键单击它。

As you select a mask in the list, its parameters are displayed on the panel next to it:在列表中选择蒙版时，其参数将显示在其旁边的面板上:

Apply	Enables or disables display of the selected mask. Can be used for convenience when configuring overlapping regions, when there are a lot of masks.启用或禁用所选蒙版的显示。可以在配置重叠区域时为了方便而使用，当有很多蒙版时。
Name	Mask name, can be edited.蒙版名称，可以编辑。
Smooth	Smoothing value, the number of additional points to be inserted between the control points of the mask.平滑值，在遮罩控制点之间插入的附加点的数量。

The Render block of settings is located at the bottom of the Projection Setup window. These settings are designed to facilitate fine-tuning of the projection by displaying the auxiliary elements on the actual projection.设置的Render块位于Projection Setup窗口的底部。这些设置旨在通过在实际投影上显示辅助元素来促进投影的微调。

Debug Color	Temporarily set individual colors for different projections. This helps to visualize overlapping regions.选项允许您为不同的投影临时设置单独的颜色。这有助于可视化重叠区域。
Show Grid	Display the warp grid in the viewport.在视窗中显示翘曲网格。
Show Warp Points	Display the selected warp points and auxiliary lines showing the point location (useful if the point is outside the projection boundaries).显示所选的翘曲点和显示点位置的辅助线（如果点在投影边界之外很有用）。
Show Blend Points	Display blend zones with selected points and auxiliary lines showing the point location (useful if the point is outside the projection boundaries). The red and green lines marking the blend zone are used for correct mapping of overlapping projections.显示带有选定点和显示点位置的辅助线的混合区域（如果点在投影边界之外很有用）。标记混合区域的红绿线用于重叠投影的正确映射。
