C Specification

An application can inspect whether the system is capable of foveated rendering by chaining an XrSystemFoveatedRenderingPropertiesVARJO structure to the XrSystemProperties structure when calling xrGetSystemProperties.

// Provided by XR_VARJO_foveated_rendering
typedef struct XrSystemFoveatedRenderingPropertiesVARJO {
    XrStructureType    type;
    void*              next;
    XrBool32           supportsFoveatedRendering;
} XrSystemFoveatedRenderingPropertiesVARJO;

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.

  • supportsFoveatedRendering is an XrBool32, indicating if current system is capable of performoning foveated rendering.

Description

The runtime should return XR_TRUE for supportsFoveatedRendering when rendering gaze is available in the system. An application should avoid using foveated rendering functionality when supportsFoveatedRendering is XR_FALSE.

Valid Usage (Implicit)
