C Specification

The XrSpatialBufferEXT structure is defined as:

// Provided by XR_EXT_spatial_entity
typedef struct XrSpatialBufferEXT {
    XrSpatialBufferIdEXT      bufferId;
    XrSpatialBufferTypeEXT    bufferType;
} XrSpatialBufferEXT;
Member Descriptions

  • bufferId the XrSpatialBufferIdEXT of the buffer data.

  • bufferType is the XrSpatialBufferTypeEXT to indicate the type of data in bufferId. The application can use bufferType to determine which function to use to retrieve the actual data of the buffer.

Some spatial components have variable-sized data and therefore require using the two-call idiom to retrieve their data. In such cases, the spatial component data structure provides an XrSpatialBufferEXT for each variable sized buffer needed in that component’s data.

Members

For the same bufferId, the runtime must provide the same data from one component data query to another, even across one snapshot to another. A different bufferId between component data query calls indicates to the application that the data for that component may have changed.
