RENDERING PERSPECTIVE VIEWS OF A SCENE USING A SCANLINE-COHERENT LOOK-UP TABLE |
摘要 |
A method and apparatus for rendering perspective views of a 3D scene. The method of the present invention includes the steps of providing an environment map containing pixel values representing a scene (105); generating a scanline-coherent look-up table containing environment map indices ordered in scanlines (110); mapping scanlines of a viewing plane to a portion of the look-up table scanlines based upon a pitch angle of the perspective view to be rendered (115); locating pixel values in a portion of the environment map based on a yaw angle and the indices stored in the portion of the look-up table scanlines to which viewing planes are mapped (120); and writting (125) and rendering (130) the located pixel values into the viewing plane and display.
