The GetFrustum method of the SceneCamera class is used to retrieve the viewing frustum for a given pixel rectangle. The frustum is a geometric shape that represents the volume of space that the camera can see. This method is useful for determining which objects are visible within the camera's view.
To use the GetFrustum method, you need to have an instance of the SceneCamera class. You can then call this method by passing a Rect object that defines the pixel rectangle for which you want to get the frustum.
// Create a new SceneCamera instance SceneCamera camera = new SceneCamera(); // Define a pixel rectangle Rect pixelRect = new Rect(0, 0, 1920, 1080); // Get the frustum for the specified pixel rectangle Frustum frustum = camera.GetFrustum(pixelRect); // Use the frustum for visibility checks or other operations
