投影配置

The number of control points along the horizontal and vertical axes of the grid. A 2 x 2 grid is used by default.沿着网格的水平和垂直轴的控制点的数量。 默认情况下使用2 x 2网格。

注意

The maximum grid size is 32 x 32.最大网格大小为32 x 32。

Visual editor enables you to 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.可视化编辑器使您能够使用控制点和黄色控制柄为所选投影设置变形。 根据其类型，将为每个选定的控制点显示这些控制柄。

You can select control points by clicking the mouse, and also switch between them using arrow keys.您可以通过单击鼠标选择控制点，也可以使用箭头键在它们之间切换。

Multi-selection using the mouse is performed as a common selection of multiple objects; to add or remove points from the selected group, click on them holding the Ctrl key. Multi-selection using the keyboard is possible in a chain-like way using arrow keys with the Shift key pressed.使用鼠标的多选择作为多个对象的共同选择来执行;要从选定的组中添加或删除点，按住Ctrl键单击它们。 使用键盘的多选择是可能的链状方式使用箭头键与Shift键按下。

The Ctrl + Z / Ctrl + Y combinations are used for the Undo / Redo actions. Shift + Ctrl + Z cancels all transformations.Ctrl + Z / Ctrl + Y组合用于Undo / Redo操作。 Shift + Ctrl + Z取消所有转换。

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。

• Drag control points and their yellow handles to warp the projection and adjust it for the required configuration. You can also move points using arrow keys with the Ctrl key pressed.拖动控制点及其黄色控制柄可翘曲投影并根据所需配置进行调整。 您也可以使用箭头键移动点与Ctrl键按下。

  

  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。

• You can fine-tune projection warping by adjusting the parameters of each control point by selecting it and changing parameters via the following panel next to grid resolution settings:通过选择每个控制点并通过网格分辨率设置旁边的以下面板更改参数，可以通过调整每个控制点的参数来微调投影翘曲:

  

  The following parameters are available:以下参数可用:

  • Point — horizontal and vertical indices of the selected control point. Enumeration starts from the bottom left corner.Point-所选控制点的水平和垂直指数。 枚举从左下角开始。

  • Position — coordinates of the selected control point along the X and Y axes.Position-所选控制点沿X和Y轴的坐标。

    

    Coordinates for control points控制点坐标

  • Type — warping type for the selected control point:Type：所选控制点的翘曲类型:

    • — automatic linear interpolation (no control handles available)：自动线性插值（没有可用的控制柄）
    • — symmetric control handles for smooth curves：用于平滑曲线的对称控制柄
    • — asymmetric control handles (you can control each handle independently)：非对称控制柄（可以独立控制每个控制柄）
    • — automatic smooth curve (no control handles available)：自动平滑曲线（没有可用的控制柄）

The grid itself can also be moved inside the view space:网格本身也可以在视图空间内移动:

• Middle Mouse Button for panning (dragging the grid vertically or horizontally)鼠标中键用于平移（垂直或水平拖动网格）
• Mouse Scroll for zooming in and out鼠标滚动用于放大和缩小
• button to undo all panning and zooming actions and make the grid fit the window按钮撤消所有平移和缩放操作，并使网格适合窗口

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。

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

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

Manages blending in the selected area. The screen-space blend area is not affected by warping.管理所选区域中的混合。 屏幕空间混合区域不受翘曲的影响。

To select the area, click Add to start creating the blending area, 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.要选择区域，请单击Add开始创建混合区域，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。

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。

Every blend area is adjusted using the following settings:每个混合区域都使用以下设置进行调整:

• Enabled — if toggled on, enables the use of the blend area selected from the list.Enabled：如果打开，则允许使用从列表中选择的混合区域。
• Link to Projection — if toggled on, allows adjusting Alpha, Contrast, and Gamma for two blends simultaneously for better neighboring of two projections. Select the projection and the blend area from the drop-down lists and adjust the necessary parameters.Link to Projection：如果打开，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。 从下拉列表中选择投影和混合区域，并调整必要的参数。
• Name — the window to modify the blend area name.Name：修改混合区域名称的窗口。
• Alpha — transparency of the whole blended area.Alpha：整个混合区域的透明度。
• Contrast — contrast of the gradient part of the blended area.Contrast：混合区域的梯度部分的对比度。
• Gamma — gamma correction value.Gamma：伽马校准值。
