<P>PROBLEM TO BE SOLVED: To obtain a three-dimensional blade shape such as an actual blade shape, while in prior art the so-called Druzkowski transformation has been known, which uses a complex number Z, in the following transformation ω=Z+the square of b/Z, for obtaining a blade shape only in a two-dimension. <P>SOLUTION: In the definition of the square of t=i by using a complex number i where the square of i=-1, three-dimensional rectangular coordinates represented by numbers realizing T=a+bi+ct (a,b,c are real numbers) are represented with use of x=a, y=b, z=c. When, by applying these numbers, a transformation from T to T can be modelled, a transformation from a three-dimensional shape to a three-dimensional shape is obtained, and a new and complex three-dimensional curved line, curved surface, and three-dimensional shape are obtained by using the shape after transformation,. Further, if only simple three-dimensional shapes before transformation and three-dimensional moving images before transformation, and transformation T are stored, storage areas on a computer can be reduced. <P>COPYRIGHT: (C)2012,JPO&INPIT |
