C Specification

The XrCompositionLayerEquirectKHR structure is defined as:

typedef struct XrCompositionLayerEquirectKHR {
    XrStructureType            type;
    const void*                next;
    XrCompositionLayerFlags    layerFlags;
    XrSpace                    space;
    XrEyeVisibility            eyeVisibility;
    XrSwapchainSubImage        subImage;
    XrPosef                    pose;
    float                      radius;
    XrVector2f                 scale;
    XrVector2f                 bias;
} XrCompositionLayerEquirectKHR;

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.

  • layerFlags specifies options for the layer.

  • space is the XrSpace in which the pose of the equirect layer is evaluated over time.

  • eye is the eye represented by this layer.

  • subImage identifies the image XrSwapchainSubImage to use.

  • pose is an XrPosef defining the position and orientation of the center point of the sphere onto which the equirect image data is mapped, relative to the reference frame of the space.

  • radius is the non-negative radius of the sphere onto which the equirect image data is mapped. Values of zero or floating point positive infinity are treated as an infinite sphere.

  • scale is an XrVector2f indicating a scale of the texture coordinates after the mapping to 2D.

  • bias is an XrVector2f indicating a bias of the texture coordinates after the mapping to 2D.

Description

XrCompositionLayerEquirectKHR contains the information needed to render an equirectangular image onto a sphere when calling xrEndFrame. XrCompositionLayerEquirectKHR is an alias type for the base struct XrCompositionLayerBaseHeader used in XrFrameEndInfo.
