WVR_GetScenePerceptionState

WVR_EXPORT WVR_Result WVR_GetScenePerceptionState(WVR_ScenePerceptionTarget target, WVR_ScenePerceptionState * state)

Function is used to get the corresponding perception target state.

Developers can inspect the completion of the scene perception by polling WVR_GetScenePerceptionState. Check state (refer to WVR_ScenePerceptionState) is WVR_ScenePerceptionState_Completed to know the result is ready.

Version

API Level 11

Parameters

• target: input perception target , refer to WVR_ScenePerceptionTarget
• state: the returned WVR_ScenePerceptionState value

Return Value

• WVR_Success: Get scene perception state successfully.
• others: WVR_Result mean failure.

How to use

Sample function:

#include <wvr/wvr_scene.h>

if (WVR_StartScene() == WVR_Success) {
    if (WVR_StartScenePerception(WVR_ScenePerceptionTarget_2dPlane) == WVR_Success) {
        WVR_ScenePerceptionState state;
        if (WVR_GetScenePerceptionState(WVR_ScenePerceptionTarget_2dPlane, &state) == WVR_SUCCESS) {
            // wait until state is WVR_ScenePerceptionState_Completed
            if (state == WVR_ScenePerceptionState_Completed) {
                // Start scene perception with WVR_ScenePerceptionTarget_2dPlane successfully and get the state as completed.
                // Developers can call WVR_GetScenePlanes to get scene plane data
            }
        }
    } else {
        // start perception with WVR_ScenePerceptionTarget_2dPlane failed
    }
    // ...
    WVR_StopScenePerception(WVR_ScenePerceptionTarget_2dPlane);
    WVR_StopScene();
} else {
    // start scene failed!
}
