Texture rendering method, entertainment apparatus and storage medium

An entertainment apparatus for carrying out a rendering process, comprising:

• means for storing object data represented by a three-dimensional model and texture data to be rendered onto a surface of the object;
• means for dividing texture data into a plurality of texture lines each having a width of one dot and a length equal to the number of dots on one side of the texture;
• means for preparing a plurality of second three-dimensional object models, each second model based on one of said plurality of texture lines, by projecting said one texture line in a light traveling direction from a virtual light source while possessing color information by means of a shadow volume method, thereby forming a relationship between the texture line, the object model and the virtual light source in a three-dimensional space;
• and
• means for defining an intersecting part between each second object and the surface of the first object model as a region for rendering the associated texture line, thereby rendering the texture data on the surface of the first object model.

A storage medium readable by an information processing apparatus, having recorded therein a program for causing the information processing apparatus to execute a rendering process, said program comprising:

• storing object data represented by a three-dimensional model and texture data to be rendered onto a surface of the object;
• dividing texture data into a plurality of texture lines each having a width of one dot and a length equal to the number of dots in one side of the texture;
• preparing a plurality of second three-dimensional object models, each second model based on one of said plurality of texture lines, by projecting said one texture line in a light traveling direction from a virtual light source while possessing color information by means of a shadow volume method, thereby forming a relationship between the texture line, the object model and the virtual light source in a three-dimensional space;
• and
• defining an intersecting part between each second object and the surface of the first object model as a region for rendering the associated texture line, thereby rendering the texture data on the surface of the first object model.
