Based on the importance of object portions, a three-dimensional polygon display apparatus adjusts the extent to which the amount of polygon data is reduced by progressive polygon data reduction. An object is divided into object portions, which are magnified and adjusted depending on their importance or conspicuity, or the extent to which polygon reduction processing is performed is set individually. Object portions hidden inside the object are rearranged on the outside, or the enclosing object portions are deformed to expose the internal object portions on the outside. After this adjustment, polygon reduction processing is performed. One set of texture information is assigned to each vertex in the case of a development into two dimensions. If polygon vertices have been moved, the used texture information is that of the closest vertex, or an intrapolation of the texture information of surrounding vertices. |
