    • An object of the present invention is to realize a technique capable of generating a texture image from all of polygons constructing a three-dimensional shape model without a dropout and a texture image on which an editing or correcting operation can be easily performed. When a computer reads original three-dimensional model data 51, an original three-dimensional model is set in a virtual model space, and a cylindrical plane is set as a projection plane around the original three-dimensional model. A virtual projection computing unit 14 functions to virtually project a texture image corresponding to a polygon which can be projected onto the projection plane, thereby generating a projected texture image. On the other hand, by individually extracting a unit texture image corresponding to a polygon which cannot be projected onto the projection plane, thereby generating an unprojected texture image.
    • 本发明的一个目的是实现一种能够从构成没有压差的三维形状模型的所有多边形生成纹理图像的技术和可以容易地执行编辑或校正操作的纹理图像。 当计算机读取原始三维模型数据51时,将原始三维模型设置在虚拟模型空间中,并且将圆柱形平面设置为围绕原始三维模型的投影平面。 虚拟投影计算单元14用于虚拟投影与能够投影到投影平面上的多边形相对应的纹理图像,从而生成投影的纹理图像。 另一方面,通过单独提取与不能投影到投影平面上的多边形相对应的单位纹理图像,从而生成未投影的纹理图像。

    • Provided are a variable deciding method, a variable deciding device, a program and a recording medium with which model construction using time information appropriately can be achieved and prediction performance can be improved. The variable deciding device accepts an operation variable ui after batch process operation (step S21). A wavelet coefficient for said read operation variable ui is then computed (step S24). Selection means selects a wavelet coefficient which satisfies a predetermined condition from computed wavelet coefficients (step S25). The wavelet coefficient selected in such a manner is then outputted by output means as a value associated with an operation variable to be inputted.

    • When volume data of a three-dimensional object to be processed is read and stored into a predetermined storage, first, a plurality of reference planes are set and a plurality of reference distance maps each indicative of distribution of distances between the three-dimensional object and each of the reference planes are generated. Next, when an actual projection plane onto which the three-dimensional object is projected in the volume rendering is set, two or more distance maps out of the plurality of reference distance maps are converted into two or more converted distance maps in accordance with a positional relation between two or more reference planes corresponding to the two or more distance maps and the actual projection plane, and integrating the resultants, thereby generating a distance map for visualization indicative of distribution of distances between the three-dimensional object and the actual projection plane.
