Abstract:
A picture-processing apparatus for generating an expansion drawing of a surface composing a 3-dimensional object displayed on a 2-dimensional picture by expansion of a projection drawing representing a result of projection of said surface on said 2-dimensional picture, said picture-processing apparatus comprising:a computation means for computing a transformation formula prescribing an inter-drawing relation between a projection drawing of a surface composing said 3-dimensional object displayed on said 2-dimensional picture and an expansion drawing of said surface; a correction means for correcting said inter-drawing relation prescribed by said transformation formula and outputting a new inter-drawing relation as a result of correction; a projection-drawing-transforming means for transforming a projection drawing of each of a plurality of surfaces composing said 3-dimensional object into an expansion drawing of said surface; and a connection means for creating a joint drawing by joining expansion drawings of said surfaces in accordance with connection relations each associated with one of said surfaces.
