Transformation Constraint 自设变换约束

    所以，例如你可以使用目标在X 轴的位置来控制绕约束目标的Z轴旋转，规定目标X 轴的一个单位对应于约束对象Z 轴旋转10个单位。这通常用在齿轮(见下面的说明)，和基于位置的旋转。

    自设变换面板。

    Target 目标

    used to select the constraints target, and is not functional (red state) when it has none. See common constraint properties for more information.

    延伸

    By default, the Min and Max values bound the input and output values; all values outside these ranges are clipped to them. When you enable this button, the Min and Max values are no longer strict limits, but rather “markers” defining a proportional (linear) mapping between input and corresponding output values. Let us illustrate that with two graphs Fig. . In these pictures, the input range (in abscissa) is set to (1.0 to 4.0), and its corresponding output range (in ordinate), to (1.0 to 2.0). The yellow curve represents the mapping between input and output.

    Target/Owner

    Standard conversion between spaces. See common constraint properties for more information.

    影响

    Controls the percentage of affect the constraint has on the object. See for more information.

    包含输入(目标)设置。

    Location, Rotation, Scale

    模式(旋转)

    指定旋转输入要使用的 顺序， 四元数 和其他 。 默认使用约束物体的 欧拉 顺序。

    在 四元数 模式下，通道将被转换为加权角和 模式相同。

    X/Y/Z Min, Max

    每个轴(X，Y和Z)独立地控制输入值范围的下限和上限。 请注意，如果最小值高于其对应的最大值，则约束的行为就像它具有与最大值相同的值。

    映射到

    包含输出(至约束对象)的设置。

    Location, Rotation, Scale

    三个单选按钮用于选择要控制的属性类型。

    顺序

    指定在旋转约束期间使用哪种 顺序。默认为约束对象的顺序。

    X/Y/Z Source Axis

    The three axis selectors allow you to select which input axis to map to, respectively (from top to bottom), the X, Y and Z output (owner) axes.

    最小值，最大值

    The Min and Max number fields control the lower and upper bounds of the output value range, independently for each mapped axis. Note that if a min value is higher than its corresponding max value, the constraint behaves as if it had the same value as the max one.

    混合

    • 替换

      约束的结果替换现有的值。

      相乘(缩放)

      约束的结果将与现有值相乘。

      相加(位置、旋转)

      约束的值与现有的值相加。

      Before Original (Rotation)现有值之前

      The new rotation is added before the existing rotation, as if it was applied to a parent of the constraint owner.

      After Original (Rotation)现有值之后

      The new rotation is added after the existing rotation, as if it was applied to a child of the constraint owner.

    Note

    • 当使用目标的旋转变换属性作为输入，无论真正的值是什么，约束将始终”重置回” (-180, 180)范围。例如，如果目标绕 X 轴旋转420°，约束实际使用的 “X” 输入值将是：

      \(((420 + 180) modulo 360) - 180 = 60 - …\)

      这就是为什么此约束不是真的适合齿轮 ！
