C Specification

The possible foveation levels are specified by the XrFoveationLevelFB enumeration:

// Provided by XR_FB_foveation_configuration
typedef enum XrFoveationLevelFB {
    XR_FOVEATION_LEVEL_NONE_FB = 0,
    XR_FOVEATION_LEVEL_LOW_FB = 1,
    XR_FOVEATION_LEVEL_MEDIUM_FB = 2,
    XR_FOVEATION_LEVEL_HIGH_FB = 3,
    XR_FOVEATION_LEVEL_MAX_ENUM_FB = 0x7FFFFFFF
} XrFoveationLevelFB;

Description

Enumerant Descriptions

  • XR_FOVEATION_LEVEL_NONE_FB — No foveation

  • XR_FOVEATION_LEVEL_LOW_FB — Less foveation (higher periphery visual fidelity, lower performance)

  • XR_FOVEATION_LEVEL_MEDIUM_FB — Medium foveation (medium periphery visual fidelity, medium performance)

  • XR_FOVEATION_LEVEL_HIGH_FB — High foveation (lower periphery visual fidelity, higher performance)
