C Specification

The xrEnumerateSupportedSemanticLabelSetsANDROID function is defined as:

// Provided by XR_ANDROID_scene_meshing
XrResult xrEnumerateSupportedSemanticLabelSetsANDROID(
    XrInstance                                  instance,
    XrSystemId                                  systemId,
    uint32_t                                    supportedSemanticLabelSetsInputCapacity,
    uint32_t*                                   supportedSemanticLabelSetsOutputCount,
    XrSceneMeshSemanticLabelSetANDROID*         supportedSemanticLabelSets);

Parameters

Parameter Descriptions

  • instance is an XrInstance created by the application.

  • systemId is an XrSystemId retried from xrGetSystem.

  • supportedSemanticLabelSetsInputCapacity is the capacity of supportedSemanticLabelSets, or 0 to retrieve the required capacity.

  • supportedSemanticLabelSetsOutputCount is a pointer to the count of supportedSemanticLabelSets written, or a pointer to the required capacity in the case that supportedSemanticLabelSetsInputCapacity is insufficient.

  • supportedSemanticLabelSets is a pointer to an array of XrSceneMeshSemanticLabelSetANDROID. It can be NULL if supportedSemanticLabelSetsInputCapacity is 0.

  • See Buffer Size Parameters chapter for a detailed description of retrieving the required supportedSemanticLabelSets size.

Description

The application can enumerate semantic label sets supported by the system using xrEnumerateSupportedSemanticLabelSetsANDROID function.

Every system must at least support XR_SCENE_MESH_SEMANTIC_LABEL_SET_NONE_ANDROID because this enum value represents no semantic label set and can be used in the case the application does not need vertex semantics.
