Abstract:
A method of providing labels for an object defined in a three-dimensional (3D) virtual environment, the objects being presented on a two dimensional (2D) image plane through projecting the objects onto the 2D image plane in a rendering process, to generate an image that is representative of the 3D environment as observed from a viewpoint, said method comprising the steps of:establishing a location for the object as presented in the 2D image plane and assigning an object position reference point relative thereto by providing a bounding box sized to surround the object as defined in the 3D virtual environment, establishing a part of the bounding box, and projecting the location of the part onto the 2D image plane in a rendering process to generate a position therein that is representative of the object location as observed from the viewpoint; and generating a two dimensional (2D) label image which is associated with the object position reference point and movable therewith in two dimensions.
