Abstract
A clairvoyance method for 3D scene is disclosed, including the steps of acquiring parameters associated with a clairvoyance camera and parameters associated with a clairvoyance viewport; determining a 3D scene to be rendered according to the parameters associated with the clairvoyance camera; rendering the determined 3D scene to obtain a 2D image presented in the clairvoyance viewport; and composing the 2D image presented in the clairvoyance viewport and a 2D image presented in a general scene viewport. With the method of the present invention, the covered 3D scene can be made clairvoyant to be viewed in a user-controllable way, and further an object can be selected in the clairvoyant 3D scene for manipulation, without manipulating the covering object. Thus, one or more embodiments of the present invention have advantages of simple and easy operation and high efficiency.
