Abstract
A texture mapping apparatus for jointing a plurality of texture images where mapping positions are partially overlapped so as to map the texture images on a surface of a three-dimensional model. The texture mapping apparatus has a texture cutting out section which extracts a boundary between a texture portion and a background portion for each of the texture images, a texture evaluating section which weights segments obtained by segmentalizing the texture portion correlatively with a distance from the boundary using boundary information obtained by the extraction of the boundary, and a texturing blending section which calculates a mapping value by means of weighted average for overlapped portions of the plural texture images.

A texture mapping method comprising the steps of:
- extracting a boundary between a texture portion and a background portion for each of the texture images;
- weighting segments obtained by segmentalizing the texture portion correlatively with a distance from the boundary using the boundary information obtained by the extraction of the boundary;
- calculating a mapping value of an overlapped portion of the plural texture images by means of weighted average;
- and
- mapping texture portions of the plural texture images on the surface of the three-dimensional model using the calculated mapping value.
