Abstract:
1. An information processing apparatus for performing walk-through in a virtual space, comprising: an input unit adapted to input tilt angle information and a rotation parameter from an operation unit; an obtaining unit adapted to obtain a view position and a view direction of an observer from the tilt angle information and the rotation parameter; a generation unit adapted to generate a display image from a panoramic image on the basis of the view position and the view direction; and a display unit to display the generated display image and a map image on which an image indicating the view position and the view direction is displayed, wherein said obtaining unit determines an advance direction on the basis of the tilt angle information and the rotation parameter, in a case where the view position is at a position other than a branch point capable of selecting a plurality of advance directions and a direction indicated by the tilt angle information is the same as a direction indicated by previous tilt angle information and the view position is moving, said obtaining unit determines a previous advance direction as an advance direction irrespective of the input rotation parameter, and in a case where the view position is at the branch point, said obtaining unit selects as an advance direction one of the plurality of advance directions selectable at the branch point in accordance with the rotation parameter.
