The GetFrustum method of the CameraComponent class is used to retrieve the viewing frustum for a specified screen 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 a certain area of the screen.
To use the GetFrustum method, you need to have an instance of CameraComponent. You can then call this method by passing a Rect object that defines the screen rectangle for which you want to get the frustum.
The method returns a Frustum object that represents the viewing frustum for the specified screen rectangle.
// Assuming 'cameraComponent' is an instance of CameraComponent Rect screenRect = new Rect(0, 0, 1920, 1080); Frustum frustum = cameraComponent.GetFrustum(screenRect); // Use the frustum for visibility checks or other operations
