|
#### b. Unity Setup:
|
||
|
|
- Install [Unity Hub](https://unity3d.com/get-unity/download)
|
||
|

|
- Create a new Unity project.
|
||
|
|
- Go to `Asset Store` and download the `Oculus Integration` package.
|
||
|
|
- Import the package into your project.
|
||
|
|
|

### 2. USB OTG Camera Integration:
|
||
|
|
|
||
|
|
#### a. Android Manifest Permissions:
|
||
|
|
Add the necessary permissions to the AndroidManifest.xml:
|
||
|
|
```xml
|
||
|
|
<uses-permission android:name="android.permission.USB_HOST" />
|
||
|
|
<uses-feature android:name="android.hardware.usb.host" android:required="true" />
|
||
|
|
```
|
||
|
|
|
||
|
|
#### b. Accessing USB Camera:
|
||
|
|
You can use the [UVCCamera](https://github.com/saki4510t/UVCCamera) library.
|
||
|
|
Here's a basic way to integrate it:
|
||
|
|
|
||
|
|
1. Clone the UVCCamera repository.
|
||
|
|
2. Import the library into your Unity project.
|
||
|
|
3. Create a bridge class in Unity to interface with the library.
|
||
|
|
|
||
|
|
### 3. Display Camera Feed in VR:
|
||
|
|
|
||
|
|
#### a. Create a 3D Plane in Unity:
|
||
|
|
- In the Unity hierarchy, right-click and create a 3D Plane.
|
||
|
|
- This will be used to display the camera feed.
|
||
|
|
|
||
|
|
#### b. Display Camera Feed:
|
||
|
|
```csharp
|
||
|
|
public RawImage displayImage; // Drag your RawImage component here in the inspector
|
||
|
|
|
||
|
|
void UpdateCameraFeed(Texture cameraTexture)
|
||
|
|
{
|
||
|
|
displayImage.texture = cameraTexture;
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
### 4. User Interface & Controls:
|
||
|
|
|
||
|
|
#### a. Basic UI:
|
||
|
|
- Use Unity's UI system to create buttons for connecting/disconnecting the camera.
|
||
|
|
- Use Oculus Integration's `OVRInputModule` to make the UI interactive in VR.
|
||
|
|
|
||
|
|
#### b. VR Controls:
|
||
|
|
- Use the `OVRInput` class from Oculus Integration to detect button presses and controller movements.
|
||
|
|
|
||
|
|
### 5. Testing:
|
||
|
|
|
||
|
|
- Build and run your Unity project for the Android platform.
|
||
|
|
- Wear your Quest 2 and test the app's functionality.
|
||
|
|
|
||
|
|
### 6. Deployment:
|
||
|
|
|
||
|
|
- Follow Oculus' [submission guidelines](https://developer.oculus.com/distribute/latest/concepts/publish-submission-guidelines/) to submit your app to the Oculus Store.
|
||
|
|
|
||
|
|
### 7. Considerations:
|
||
|
|
|
||
|
|
- Regularly test with different USB OTG cameras to ensure broad compatibility.
|
||
|
|
- Monitor battery usage and optimize as necessary.
