The GetFrustum method of the CameraComponent class calculates and returns a Frustum object based on the specified screen rectangle. This method is useful for determining the visible area of the camera in world space, which can be used for various rendering and culling operations.
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 calculate the frustum.
// Assuming 'cameraComponent' is an instance of CameraComponent Rect screenRect = new Rect(0, 0, 1920, 1080); Frustum frustum = cameraComponent.GetFrustum(screenRect); // Use the frustum for further operations, such as culling or rendering
