Patent ID: 8259116

Claim:
An image creating device comprising: a parameter acquiring unit that acquires an environment parameter of the environment around a character placed in a virtual space, in each direction from the character; a reference curve setting unit that sets a predetermined reference curve surrounding the character, the reference curve being centered around the character and being located within a plane, the reference curve including a predetermined number plurality of reference points; a trajectory point setting unit that sets a trajectory point associated with each reference point in a position moved in a predetermined direction from the associated reference point in said set reference curve, the distance between each reference point and the associated trajectory point being a function of the value of said environment parameter at the respective reference point acquired in the direction from the character toward the reference point, the predetermined direction being perpendicular to the plane; and an image creating unit that creates an image showing a trajectory curve, passing through said set trajectory points, and the character, the character and the curve being as viewed from the point of view placed in the virtual space.
