Detailed Description

This type provides a way to manage spatial anchors, which are points in the physical world that can be tracked and associated with virtual content.

You can use it like so:

XrSpatialAnchorListModel {
    id: anchorModel
    filterMode: XrSpatialAnchorListModel.Labels
    labels: XrSpatialAnchorListModel.Ceiling | XrSpatialAnchorListModel.Floor
    // ... other properties and methods ...

}

Property Documentation

classificationFilter : enumeration

Holds the classification flag used for filtering spatial anchors.

The ClassificationFlag filter is represented as a combination of flags:

Constant	Value
`Wall`
`Ceiling`
`Floor`
`Table`
`Seat`
`Window`
`Door`
`Other`

classificationStringFilter : string

Holds the classification strings used for filtering spatial anchors.

If the FilterMode is set to Classification, this property can be used to provide a list of additional classification string to filter on. These labels will then be matched against the same value as reported by XrSpatialAnchor::classificationString property of the spatial anchor.

Note: Only spatial anchors that are classified as Other will be checked against this filter.

filterMode : enumeration

Specifies the filter mode for spatial anchors.

Holds the filter mode. The filter mode can be one of the following:

Constant	Description
`All`	Show all spatial anchors.
`Classification`	Show spatial anchors based on the provided classification filter flag.
`Identifier`	Show spatial anchors based matching the provided Identifiers.

identifierFilter : list

Holds the list of identifiers for filtering spatial anchors.
