ABSTRACT:
A method and apparatus for generating perspective views of a scene. With a viewing position at the center of to be cylindrical environment map, different views can be obtained by rotating the viewing direction either horizontally or vertically. The horizontal construction method of the present invention generally involves the steps of: determining the portion of the cylindrical map to be viewed; vertically interpolating pixel values in the portion of the cylindrical map to be viewed and mapping to a viewing plane; and displaying the viewing plane. The vertical construction method of the present invention generally involves the steps of: determining the portion of the cylindrical map to be viewed; vertically interpolating pixel values in the portion of the cylindrical map robe viewed and mapping to a vertical plane; horizontally interpolating pixel values in the vertical plane and mapping to the viewing plane; and displaying the viewing plane.
