PURPOSE:To speedily prevent the deterioration of picture quality with the aid of arbitrary profile angle by deciding the direction of interpolation from the angle of an object fault plane, deciding the density value of a point on the fault plane from the interpolation, and distributing the density value in a two-dimensional plane after projection. CONSTITUTION:Two coordinates are chosen from among coordinates X, Y, Z on the profile to be projected, and the rest one coordinate is obtained by the formula on the fault plane. There are three ways in this selection. The amount of change of a projection point is determined by this way of selection, and the method for interpolation with the smallest amount of change among these is utilized to the generation of fault plane afterwards. Then, the value of the object point of the projection is decided while performing interpolation in the direction of the interpolation adapted in the front stage. On the other hand, the point is projected to a two-dimensional coordinate system 10 formed on the fault plane based on the projection conversion formula. After the projection, the addition of the value of a point 11 is performed while distributing it to a neighboring lattice point 12, and the fault picture is finally obtained. Thus, high-quality fault plane generation can be performed with the small number of access of a three-dimensional external memory. |
