+The **NativeBuffer** module provides APIs for you to apply for, use, and release the shared memory, and query memory properties.
+
+The following scenario is common for **NativeBuffer** development:
+
+Use the native APIs provided by **NativeBuffer** to create an **OH_NativeBuffer** instance, obtain memory properties, and map the corresponding ION memory to the process address space.
+

+
+For details about the APIs, see [native_buffer](../reference/native-apis/_o_h___native_buffer.md).
+
+## How to Develop
+
+The following describes how to use the native APIs provided by **NativeBuffer** to create an **OH_NativeBuffer** instance, obtain memory properties, and map the corresponding ION memory to the process address space.
+
+**Header File**
+```c++
+#include <native_buffer/native_buffer.h>
+```
+
+1. Create an **OH_NativeBuffer** instance.
+    ```c++
+    OH_NativeBuffer_Config config {
+        .width = 0x100,
+        .height = 0x100,
+    };
+    OH_NativeBuffer* buffer = OH_NativeBuffer_Alloc(&config);
+    if (buffer == nullptr) {
+        std::cout << "OH_NativeBuffer_Alloc Failed" << std::endl;
+    }
+    ```
+   
+2. Map the ION memory corresponding to the **OH_NativeBuffer** instance to the process address space by calling **OH_NativeBuffer_Map**, if the application needs to access the memory space of the buffer.
+    ```c++
+    // Map the ION memory to the process address space.
+    void* virAddr = nullptr;
+    int32_t ret = OH_NativeBuffer_Map(buffer, &virAddr); // After mapping, the start address of the memory is returned through the parameter virAddr.
+    if (ret != 0) {
+        std::cout << "OH_NativeBuffer_Map Failed" << std::endl;
+    }
+
+    // Unmap the ION memory from the process address space when it is no longer needed.
+    ret = OH_NativeBuffer_Unmap(buffer);
+    if (ret != 0) {
+        std::cout << "OH_NativeBuffer_Unmap Failed" << std::endl;
+    }
+    ```
+
+3. Obtain the memory properties.
+    ```c++
+    // Obtain the properties of the OH_NativeBuffer instance.
+    OH_NativeBuffer_Config config = {};
+    OH_NativeBuffer_GetConfig(buffer, &config);
+    // Obtain the sequence number of the OH_NativeBuffer instance.
+     uint32_t hwBufferID = OH_NativeBuffer_GetSeqNum(buffer);
+    ```
+
+4. Destroy the **OH_NativeBuffer** instance.
+    ```c++
+    // Call OH_NativeBuffer_Unreference to decrease the reference count by 1. When the reference count reaches 0, the instance is destroyed.
+    ret = OH_NativeBuffer_Unreference(buffer);
+    if (ret != 0) {
+        std::cout << "OH_NativeBuffer_Unreference Failed" << std::endl;
+    }
+    ```

+# NativeImage Development
+
+## When to Use
+
+**NativeImage** is a module provided by OpenHarmony for associating a surface with a OpenGL external texture. It functions as the consumer of a graphics queue. It provides APIs for you to obtain and use a buffer, and output the buffer content to a OpenGL external texture.
+
+The following scenario is common for **NativeImage** development:
+
+Use the native APIs provided by **NativeImage** to create a **NativeImage** instance as the consumer and obtain the corresponding **NativeWindow** instance (functioning as the producer). Use the APIs provided by **NativeWindow** to fill in and flush the buffer, and then use the APIs provided by **NativeImage** to update the buffer content to a OpenGL ES texture. The **NativeImage** module must be used together with the **NativeWindow**, **NativeBuffer**, **EGL**, and **GLES3** modules.
+
+## Available APIs
+
+| API| Description|
+| -------- | -------- |
+| OH_NativeImage_Create (uint32_t textureId, uint32_t textureTarget) | Creates an **OH_NativeImage** instance to be associated with the OpenGL ES texture ID and target.|
+| OH_NativeImage_AcquireNativeWindow (OH_NativeImage \*image) | Obtains a **NativeWindow** instance associated with an **OH_NativeImage** instance. You need to call **OH_NativeWindow_DestroyNativeWindow** to release the **NativeWindow** instance when it is no longer needed.|
+| OH_NativeImage_AttachContext (OH_NativeImage \*image, uint32_t textureId) | Attaches an **OH_NativeImage** instance to the current OpenGL ES context. The OpenGL ES texture will be bound to an **GL_TEXTURE_EXTERNAL_OES** instance and updated through the **OH_NativeImage** instance.|
+| OH_NativeImage_DetachContext (OH_NativeImage \*image) | Detaches an **OH_NativeImage** instance from the current OpenGL ES context.|
+| OH_NativeImage_UpdateSurfaceImage (OH_NativeImage \*image) | Updates the OpenGL ES texture associated with the latest frame through an **OH_NativeImage** instance.|
+| OH_NativeImage_GetTimestamp (OH_NativeImage \*image) | Obtains the timestamp of the texture image that recently called the **OH_NativeImage_UpdateSurfaceImage** function.|
+| OH_NativeImage_GetTransformMatrix (OH_NativeImage \*image, float matrix[16]) | Obtains the transform matrix of the texture image that recently called the **OH_NativeImage_UpdateSurfaceImage** function.|
+| OH_NativeImage_Destroy (OH_NativeImage \*\*image) | Destroys an **OH_NativeImage** instance created by calling **OH_NativeImage_Create**. After the instance is destroyed, the pointer to the **OH_NativeImage** instance is assigned **NULL**.|
+
+For details about the APIs, see [native_image](../reference/native-apis/_o_h___native_image.md).

+    ```
+   
+2. Create an **OH_NativeImage** instance.
+    ```c++
+    // Create an OpenGL ES texture.
+    GLuint textureId;
+    glGenTextures(1, &textureId);
+    // Create an OH_NativeImage instance, which will be associated with an OpenGL ES texture.
+    OH_NativeImage* image = OH_NativeImage_Create(textureId, GL_TEXTURE_2D);
+    ```
+
+3. Obtain a **NativeWindow** instance that functions as the producer.
+    ```c++
+    // Obtain a NativeWindow instance.
+    OHNativeWindow* nativeWindow = OH_NativeImage_AcquireNativeWindow(image);
+    ```
+
+4. Write the produced content to a **NativeWindowBuffer** instance.
+    1. Obtain a NativeWindowBuffer instance from the NativeWindow instance.
+    ```c++
+    OHNativeWindowBuffer* buffer = nullptr;
+    int fenceFd;
+    // Obtain a NativeWindowBuffer instance by calling OH_NativeWindow_NativeWindowRequestBuffer.
+    OH_NativeWindow_NativeWindowRequestBuffer(nativeWindow, &buffer, &fenceFd);

+    int32_t height = 0x100;
+    ret = OH_NativeWindow_NativeWindowHandleOpt(nativeWindow, code, width, height);
+    ```
+    3. Write the produced content to the **NativeWindowBuffer** instance.
+    ```c++
+    static uint32_t value = 0x00;
+    value++;
+    uint32_t *pixel = static_cast<uint32_t *>(handle->virAddr);
+    for (uint32_t x = 0; x < width; x++) {

+            *pixel++ = value;
+        }
+    }
+    ```
+    4. Flush the **NativeWindowBuffer** to the **NativeWindow**.
+    ```c++
+    // Set the refresh region. If Rect in Region is a null pointer or rectNumber is 0, all contents in the NativeWindowBuffer are changed.
+    Region region{nullptr, 0};
+    // Flush the buffer to the consumer through OH_NativeWindow_NativeWindowFlushBuffer, for example, by displaying it on the screen.
+    OH_NativeWindow_NativeWindowFlushBuffer(nativeWindow, buffer, fenceFd, region);
+    ```
+    5. Destroy the **NativeWindow** instance when it is no longer needed.
+    ```c++
+    OH_NativeWindow_DestroyNativeWindow(nativeWindow);
+    ```
+
+5. Update the content to the OpenGL texture.
+    ```c++
+    // Update the content to the OpenGL texture.
+    int32_t ret = OH_NativeImage_UpdateSurfaceImage(image);
+    if (ret != 0) {
+        std::cout << "OH_NativeImage_UpdateSurfaceImage failed" << std::endl;
+    }
+    // Obtain the timestamp and transform matrix of the texture image that recently called the **OH_NativeImage_UpdateSurfaceImage** function.
+    int64_t timeStamp = OH_NativeImage_GetTimestamp(image);
+    float matrix[16];
+    ret = OH_NativeImage_GetTransformMatrix(image, matrix);
+    if (ret != 0) {
+        std::cout << "OH_NativeImage_GetTransformMatrix failed" << std::endl;
+    }
+    ```
+
+6. Unbind the OpenGL texture and bind it to a new external texture.
+    ```c++
+    // Detach an OH_NativeImage instance from the current OpenGL ES context.
+    ret = OH_NativeImage_DetachContext(image);
+    if (ret != 0) {
+        std::cout << "OH_NativeImage_DetachContext failed" << std::endl;
+    }
+    // Attach the OH_NativeImage instance to the current OpenGL ES context. The OpenGL ES texture will be bound to an GL_TEXTURE_EXTERNAL_OES instance and updated through the OH_NativeImage instance.
+    GLuint textureId2;
+    glGenTextures(1, &textureId2);
+    ret = OH_NativeImage_AttachContext(image, textureId2);
+    ```
+
+7. Destroy the **OH_NativeImage** instance when it is no longer needed.
+    ```c++
+    // Destroy the OH_NativeImage instance.
+    OH_NativeImage_Destroy(&image);
+    ```

+# NativeVSync Development
+
+## When to Use
+
+The **NativeVSync** module is used to obtain virtual synchronization (VSync) signals from the system. It provides APIs for creating and destroying an **OH_NativeVSync** instance and setting the VSync callback function, which is triggered when a VSync signal arrives.
+
+## Available APIs
+
+| API| Description:|
+| -------- | -------- |
+| OH_NativeVSync_Create (const char \*name, unsigned int length) | Creates an **OH_NativeVSync** instance. A new **OH_NativeVSync** instance is created each time this function is called.|
+| OH_NativeVSync_Destroy (OH_NativeVSync \*nativeVsync) | Destroys an **OH_NativeVSync** instance.|
+| OH_NativeVSync_FrameCallback (long long timestamp, void \*data) | Sets a callback function. **timestamp** indicates the timestamp, and **data** indicates the input parameter of the callback function. |
+| OH_NativeVSync_RequestFrame (OH_NativeVSync \*nativeVsync, OH_NativeVSync_FrameCallback callback, void \*data) | Requests the next VSync signal. When the signal arrives, a callback function is invoked.|
+
+For details about the APIs, see [native_vsync](../reference/native-apis/_native_vsync.md).
+
+## How to Develop
+
+The following steps describe how to use the native APIs provided by **NativeVSync** to create and destroy an **OH_NativeVSync** instance and set the VSync callback function.
+
+**Header File**
+```c++
+#include <native_vsync/native_vsync.h>
+```
+
+1. Prepare a VSync callback function.
+    ```c++
+    static bool flag = false;
+    static void OnVSync(long long timestamp, void* data)
+    {
+        flag = true;
+        std::cout << "OnVSync: " << timestamp << std::endl;
+    }
+    OH_NativeVSync_FrameCallback callback = OnVSync; // The callback function must be of the OH_NativeVSync_FrameCallback type.
+    ```
+2. Create an **OH_NativeVSync** instance.
+    ```c++
+    char name[] = "hello_vsync";
+    OH_NativeVSync* nativeVSync = OH_NativeVSync_Create(name, strlen(name));
+    ```
+
+3. Set the VSync callback function through the **OH_NativeVSync** instance.
+    ```c++
+    OH_NativeVSync_RequestFrame(nativeVSync, callback, nullptr);
+    while (!flag) { // Check the flag value. The while loop exits only after the VSync callback function is executed, indicating that a VSync signal is received.
+        std::cout << "wait for vsync!\n";
+        sleep(1);
+    }
+    std::cout << "vsync come, end this thread\n";
+    ```
+
+4. Destroy the **OH_NativeVSync** instance.
+    ```c++
+    OH_NativeVSync_Destroy(nativeVSync); // Destroy the OH_NativeVSync instance when the application does not need to receive VSync signals.
+    ```

+# Vulkan Development
+
+## When to Use
+
+Vulkan is a set of graphics APIs for 2D and 3D rendering. Creating a **VkSurfaceKHR** instance is a key step, since **VkSurfaceKHR** work with the **OHNativeWindow** module to implement buffer recycling.
+
+A **VkSurfaceKHR** instance is obtained through an **OHNativeWindow**, which is obtained from the **\<XComponent>**. Therefore, the **OHNativeWindow** module must be used together with the **XComponent** and **NativeWindow** modules.
+
+## Available APIs
+
+| API| Description| 
+| -------- | -------- |
+| vkCreateSurfaceOHOS (VkInstance instance, const VkSurfaceCreateInfoOHOS\* pCreateInfo, const VkAllocationCallbacks\* pAllocator, VkSurfaceKHR\* pSurface) | Creates a **VkSurfaceKHR** instance.| 
+
+For details about the APIs, see [Vulkan](../reference/native-lib/third_party_vulkan/vulkan-symbol.md).
+
+## How to Develop
+
+The following steps illustrate how to create a **VkSurfaceKHR** instance.
+
+**Header File**
+```c++
+#include <ace/xcomponent/native_interface_xcomponent.h>
+#include <native_window/external_window.h>
+#include <vulkan/vulkan.h>
+```
+
+1. Create a Vulkan instance.
+    ```c++
+    VkInstance instance = VK_NULL_HANDLE;
+
+    VkApplicationInfo appInfo = {};
+    appInfo.sType = VK_STRUCTURE_TYPE_APPLICATION_INFO;
+    appInfo.pApplicationName = "vulkanExample";
+    appInfo.pEngineName = "vulkanExample";
+    appInfo.apiVersion = VK_API_VERSION_1_3;
+    
+    VkInstanceCreateInfo instanceCreateInfo = {};
+    instanceCreateInfo.sType = VK_STRUCTURE_TYPE_INSTANCE_CREATE_INFO;
+    instanceCreateInfo.pNext = NULL;
+    instanceCreateInfo.pApplicationInfo = &appInfo;
+
+    std::vector<const char*> instanceExtensions = {
+        VK_KHR_SURFACE_EXTENSION_NAME,
+        VK_OHOS_SURFACE_EXTENSION_NAME // Surface extension.
+    };
+    instanceCreateInfo.enabledExtensionCount = static_cast<uint32_t>(instanceExtensions.size());
+    instanceCreateInfo.ppEnabledExtensionNames = instanceExtensions.data();
+
+    vkCreateInstance(&instanceCreateInfo, nullptr, &instance);
+    ```
+
+2. Obtain an **OHNativeWindow** instance.
+
+    The **OHNativeWindow** instance is obtained from the **\<XComponent>**. For details about how to use the **\<XComponent>**, see [XComponent](../ui/arkts-common-components-xcomponent.md) and [XComponent Development](xcomponent-guidelines.md).
+    1. Add an **\<XComponent>** to **ets/pages/Index.ets**.
+    ```ts
+    XComponent({
+        id: 'xcomponentId',
+        type: 'surface',
+        libraryname: 'entry'
+    })
+    .margin({ bottom: 20 })
+    .width(360)
+    .height(360)
+    ```
+    2. Obtain an **OHNativeWindow** instance from the **\<XComponent>**.
+    ```c++
+    // Callback function of the \<XComponent> triggered when a surface is created.
+    void OnSurfaceCreatedCB(OH_NativeXComponent *component, void *window) {
+        // You can obtain an OHNativeWindow instance from the callback function.
+        OHNativeWindow* nativeWindow = static_cast<OHNativeWindow*>(window);
+    }
+
+    EXTERN_C_START
+    static napi_value Init(napi_env env, napi_value exports)
+    {
+        napi_property_descriptor desc[] = {
+            { "add", nullptr, Add, nullptr, nullptr, nullptr, napi_default, nullptr }
+        };
+        napi_define_properties(env, exports, sizeof(desc) / sizeof(desc[0]), desc);
+
+        // Declare an XComponent callback.
+        OH_NativeXComponent_Callback callback;
+        // Register the OnSurfaceCreated callback function.
+        callback.OnSurfaceCreated = OnSurfaceCreatedCB;
+        
+        char idStr[OH_XCOMPONENT_ID_LEN_MAX + 1] = {};
+        uint64_t idSize = OH_XCOMPONENT_ID_LEN_MAX + 1;
+        napi_value exportInstance = nullptr;
+        OH_NativeXComponent *nativeXComponent = nullptr;
+        // Obtain a native XComponent.
+        napi_get_named_property(env, exports, OH_NATIVE_XCOMPONENT_OBJ, &exportInstance);
+        napi_unwrap(env, exportInstance, reinterpret_cast<void **>(&nativeXComponent));
+        // Register the callback function for the native XComponent.
+        OH_NativeXComponent_RegisterCallback(nativeXComponent, &callback);
+        
+        return exports;
+    }
+    ```
+
+3. Create a **VkSurfaceKHR** instance.
+    ```c++
+    VkSurfaceKHR surface = VK_NULL_HANDLE;
+    VkSurfaceCreateInfoOHOS surfaceCreateInfo = {};
+    surfaceCreateInfo.sType = VK_STRUCTURE_TYPE_SURFACE_CREATE_INFO_OHOS;
+    surfaceCreateInfo.window = nativeWindow; // nativeWindow is obtained from the OnSurfaceCreatedCB callback function in the previous step.
+    int err = vkCreateSurfaceOHOS(instance, &surfaceCreateInfo, NULL, &surface);
+    if (err != VK_SUCCESS) {
+        std::cout << "Could not create surface!" << std::endl;
+    }
+    ```
