Description

Enumerant Descriptions

  • XR_TRACKING_OPTIMIZATION_SETTINGS_HINT_NONE_QCOM  — Used by the application to indicate that it does not have a preference to optimize for. The run-time is understood to choose a balanced approach.

  • XR_TRACKING_OPTIMIZATION_SETTINGS_HINT_LONG_RANGE_PRIORITIZATION_QCOM  — Used by the application to indicate that it prefers tracking to be optimized for long range, possibly at the expense of competing interests.

  • XR_TRACKING_OPTIMIZATION_SETTINGS_HINT_CLOSE_RANGE_PRIORITIZATION_QCOM  — Used by the application to indicate that it prefers tracking to be optimized for close range, possibly at the expense of competing interests.

  • XR_TRACKING_OPTIMIZATION_SETTINGS_HINT_LOW_POWER_PRIORITIZATION_QCOM  — Used by the application to indicate that it prefers tracking to be optimized for low power consumption, possibly at the expense of competing interests.

  • XR_TRACKING_OPTIMIZATION_SETTINGS_HINT_HIGH_POWER_PRIORITIZATION_QCOM  — Used by the application to indicate that it prefers tracking to be optimized for increased tracking performance, possibly at the cost of increased power consumption.

  • XR_TRACKING_OPTIMIZATION_SETTINGS_HINT_LONG_RANGE_PRIORIZATION_QCOM  — Backward-compatibility alias containing typo. (Added by the XR_QCOM_tracking_optimization_settings extension)

  • XR_TRACKING_OPTIMIZATION_SETTINGS_HINT_CLOSE_RANGE_PRIORIZATION_QCOM  — Backward-compatibility alias containing typo. (Added by the XR_QCOM_tracking_optimization_settings extension)

  • XR_TRACKING_OPTIMIZATION_SETTINGS_HINT_LOW_POWER_PRIORIZATION_QCOM  — Backward-compatibility alias containing typo. (Added by the XR_QCOM_tracking_optimization_settings extension)

  • XR_TRACKING_OPTIMIZATION_SETTINGS_HINT_HIGH_POWER_PRIORIZATION_QCOM  — Backward-compatibility alias containing typo. (Added by the XR_QCOM_tracking_optimization_settings extension)
