Abstract
Techniques for selecting a portion of a 3D virtual environment are disclosed, where the portion of the 3D virtual environment may be one or more objects in the 3D virtual environment or one of scenes in the 3D virtual environment. A motion sensitive device (controller) is used. The controller generates sensor data sufficient to derive position and orientation of the controller in six degrees of freedom. In one embodiment, when selecting the portion of the 3D virtual environment, the controller generates a ray to an interaction of a display screen provided to display the 3D virtual environment, wherein the ray is further projected into the 3D virtual environment by a ray tracing technique as if the user had a real laser pointer that crosses from the physical world into the 3D virtual environment being displayed. Further a user is optionally to use a secondary input device to select one or more points or objects in a 3D space to control a distance along the ray being used.
