## Detailed Description

The InstanceRange QML type is used to specify the range of variation for RandomInstancing attributes.

## Property Documentation

from : Variant

This property specifies the lower bound of the range. The type needs to match the type of the attribute that this range is applied to.

proportional : bool

This property determines whether the components of the attribute vary proportionally or independently. The default value is `true`, meaning that all components are independent.

For example, the following defines a scaling range that preserves the aspect ratio of the model:

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

This defines a greyscale color range:

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

While the following defines a range that covers all colors

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

to : Variant

This property specifies the upper bound of the range. The type needs to match the type of the attribute that this range is applied to.
