How to use

Here is an example for WVR_GetSupportedFeatures:

#include <wvr/wvr.h>
#include <wvr/wvr_arena.h>
#include <wvr/wvr_hand.h>
#include <wvr/wvr_eyetracking.h>
#include <wvr/wvr_eyeexp.h>
#include <wvr/wvr_lip.h>
#include <wvr/wvr_tracker.h>

uint64_t supported = WVR_GetSupportedFeatures();

if (supported & WVR_SupportedFeature_PassthroughOverlay) {
    // This device supports passthrough overlay feature
    WVR_ShowPassThroughOverlay(true)
}

if (supported & WVR_SupportedFeature_HandTracking) {
    // This device supports hand tracking feature
    // WVR_StartHandTracking
}

if (supported & WVR_SupportedFeature_HandGesture) {
    // This device supports hand gesture feature
    // WVR_StartHandGesture
}

if (supported & WVR_SupportedFeature_EyeTracking) {
    // This device supports eye tracking feature
    WVR_StartEyeTracking();
}

if (supported & WVR_SupportedFeature_EyeExp) {
    // This device supports eye expression feature
    WVR_StartEyeExp();
}

if (supported & WVR_SupportedFeature_LipExp) {
    // This device supports lip expression feature
    WVR_StartLipExp();
}

if (supported & WVR_SupportedFeature_Tracker) {
    // This device supports tracker feature
    WVR_StartTracker();
}
