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();
}
