Abstract:
1. A three dimensional drawing model generation method for generating a texture model for drawing a three-dimensional model as a texture image, comprising the steps of: flattening the surface of said three-dimensional model; acquiring the texture image of said flattened surface from the drawing image of said three-dimensional model; and generating said texture model by the polygons of said flattened surface and said texture image, wherein said step of flattening comprises: a step of detecting a hollow of said three-dimensional model; a step of separating said three-dimensional model at said hollow and keeping a portion directly beneath the detected hollow; a step of flattening each surface of each separated portion of said three-dimensional model comprising said separated hollow portion and a separate other portion except said hollow portion; a step of generating a model that encloses the entirety of said three-dimensional model; a step of calculating the distance from the model that encloses the entirety of said model to said three-dimensional model; and a step of displaying said three-dimensional model wherein all of said steps are executed on a computer which comprises a CPU, a storage device, a user input and a display.
