详细说明

InstanceRange QML 类型用于指定RandomInstancing 属性的变化范围。

属性文档

from : Variant

该属性指定范围的下限。该类型需要与应用此范围的属性类型相匹配。

proportional : bool

该属性决定了属性的组成部分是按比例变化还是独立变化。默认值为true ，表示所有分量都是独立的。

例如，下面定义的缩放范围保留了模型的长宽比：

InstanceRange {
    from: Qt.vector3d(1, 1, 1)
    to: Qt.vector3d(5, 5, 5)
    proportional: true
}

这定义了一个灰度颜色范围：

InstanceRange {
    from: "black"
    to: "white"
    proportional: true
}

而下面定义了一个涵盖所有颜色的范围

InstanceRange {
    from: "black"
    to: "white"
}

to : Variant

该属性指定了范围的上限。类型需要与应用此范围的属性类型相匹配。
