Method and apparatus for editing three-dimensional model, and computer readable medium

An apparatus for editing a three-dimensional model in which texture images are mapped onto three-dimensional data including polygons, the apparatus comprising:

• an extraction portion for extracting a vertex located at a seam portion between the texture images out of vertexes forming the polygons as a seam vertex;
• a vertex extraction list for storing the extracted seam vertexes;
• a portion for changing the vertexes other than the seam vertexes to modify the three-dimensional data with the extracted seam vertexes being maintained;
• and
• a portion for mapping the texture images onto the modified three-dimensional data.

A computer readable medium storing a computer program for editing a three-dimensional model in which texture images are mapped onto three-dimensional data including polygons, the program making a computer perform the processing of:

• extracting a vertex located at a seam portion between the texture images out of vertexes of the polygons as a seam vertex;
• storing the extracted seam vertexes in a vertex extraction list;
• and
• changing the vertexes other than the seam vertexes to modify the three-dimensional data without changing the seam vertexes stored in the vertex extraction list.
