Abstract

A method and an apparatus for processing data enables to display a preview image rapidly in case of processing large volume of data. Index data are generated by rendering the large amount of bit map data and stored in addition to the three-dimensional bit map data. By means that the two-dimensional image resulted from the rendering process is made prepared in advance before accepting the user'"'"'s command for display and edit, the preview of the content of the data can be displayed rapidly at real-time when the user issues the command interactively.
