C Specification

The xrCreateSpatialAnchorMSFT function is defined as:

XrResult xrCreateSpatialAnchorMSFT(
    XrSession                                   session,
    const XrSpatialAnchorCreateInfoMSFT*        createInfo,
    XrSpatialAnchorMSFT*                        anchor);

Parameters

Parameter Descriptions

Description

Creates an XrSpatialAnchorMSFT handle representing a spatial anchor that will track a fixed location in the physical world over time. That real-world location is specified by the position and orientation of the specified pose within space at time.

If space cannot be located relative to the environment at the moment of the call to xrCreateSpatialAnchorMSFT, the runtime must return XR_ERROR_CREATE_SPATIAL_ANCHOR_FAILED_MSFT.

After the anchor is created, the runtime should then adjust its position and orientation over time relative to other spaces so as to maintain maximum alignment to its original real-world location, even if that changes the anchor’s relationship to the original space used to initialize it.
