C Specification

The XrBoundary2DFB structure is defined as:

// Provided by XR_FB_scene
typedef struct XrBoundary2DFB {
    XrStructureType    type;
    const void*        next;
    uint32_t           vertexCapacityInput;
    uint32_t           vertexCountOutput;
    XrVector2f*        vertices;
} XrBoundary2DFB;

Members

Member Descriptions

  • type is the XrStructureType of this structure.

  • next is NULL or a pointer to the next structure in a structure chain. No such structures are defined in core OpenXR or this extension.

  • vertexCapacityInput is the capacity of the vertices array, in number of vertices, or 0 to indicate a request to retrieve the required capacity.

  • vertexCountOutput is the count of XrVector2f written, or the required capacity in the case that vertexCapacityInput is insufficient.

  • vertices is a pointer to an array of XrVector2f, but can be NULL if vertexCapacityInput is 0.

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

Description

This structure is used by the xrGetSpaceBoundary2DFB function to provide the application with the XrVector2f vertices representing the a spatial entity with a boundary.
