C Specification

The XrSwapchainCreateInfo structure is defined as:

typedef struct XrSwapchainCreateInfo {
    XrStructureType           type;
    const void*               next;
    XrSwapchainCreateFlags    createFlags;
    XrSwapchainUsageFlags     usageFlags;
    int64_t                   format;
    uint32_t                  sampleCount;
    uint32_t                  width;
    uint32_t                  height;
    uint32_t                  faceCount;
    uint32_t                  arraySize;
    uint32_t                  mipCount;
} XrSwapchainCreateInfo;

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.

  • createFlags is a bitmask of XrSwapchainCreateFlagBits describing additional properties of the swapchain.

  • usageFlags is a bitmask of XrSwapchainUsageFlagBits describing the intended usage of the swapchain’s images. The usage flags define how the corresponding graphics API objects are created. A mismatch may result in swapchain images that do not support the application’s usage.

  • format is a graphics API-specific texture format identifier. For example, if the graphics API specified in xrCreateSession is Vulkan, then this format is a Vulkan format such as VK_FORMAT_R8G8B8A8_SRGB. The format identifies the format that the runtime will interpret the texture as upon submission. Valid formats are indicated by xrEnumerateSwapchainFormats.

  • sampleCount is the number of sub-data element samples in the image, must not be 0 or greater than the graphics API’s maximum limit.

  • width is the width of the image, must not be 0 or greater than the graphics API’s maximum limit.

  • height is the height of the image, must not be 0 or greater than the graphics API’s maximum limit.

  • faceCount is the number of faces, which can be either 6 (for cubemaps) or 1.

  • arraySize is the number of array layers in the image or 1 for a 2D image, must not be 0 or greater than the graphics API’s maximum limit.

  • mipCount describes the number of levels of detail available for minified sampling of the image, must not be 0 or greater than the graphics API’s maximum limit.
