PURPOSE: A texture mapping apparatus is provided to difficult to be deteriorated of a picture quality of texture even when deformation takes place, such as, for example, at the time of zooming. CONSTITUTION: Picture data which has been caused to undergo repetitive transform encoding (e.g., fractal encoding) is caused to undergo repetitive transform decoding while implementing scaling at a repetitive transform decoding unit(20) to temporarily preserve the decoded picture thus obtained at a buffer section 9. At the shape information calculating section(12), an approach is employed to calculate shape of object while implementing scaling thereto to send the object shape thus obtained (e.g., polygon) to a picture mapping section 10 to implement mapping to decoded picture from the buffer section(9). Thus, there is realized a texture mapping apparatus such that picture quality of texture is difficult to be deteriorated even when deformation takes place, such as, for example, at the time of zooming, etc. |
