Abstract
According to the present invention, a method is provided for assigning or converting volume data values defined at the center of cells to volume data values at node points, considering the residuals. Volume data values at a plurality of node points are computed from a volume data value at a center of each of a plurality of cells which are composed of the plurality of node points, where the position and the ID of each node point are stored in a memory with relation to each corresponding node point, and the volume data value at each node point is computed so that a value determined by (a) weighting a residual value which is the difference between a cell-inside value at a point inside a cell and a volume data value at the center of the cell by a predetermined weighting function, where the cell-inside value is calculated by interpolating a volume data at each node point which composes the cell, and then (b) accumulating the weighted residual value over all regions of the cell for each of the plurality of cells and (c) summing up the accumulations, is set to zero.
