PURPOSE:To render an optional mapping data based on the table data and to display the mapping data at a high speed in regard of a rendering method by storing the positional relation between the mapping data and the shape data shown on a screen in the table data when the mapping data are stuck on the shape data and also by storing the display information on the shape data in the table data. CONSTITUTION:The mapping data 1 are stuck on the three-dimensional shape data 3. At the same time, the positional relation of a pixel unit between both data 1 and 3 which is shown on a screen and the display information of a pixel unit on the data 3 are calculated and registered in the table data 5. Furthermore the display information of a pixel unit taken out of the data 5 and shown on the screen is synthesized with the display information taken out of the data 1. This synthesization is repeated in a rendering process 4 for all pixels shown on the screen. Then the images synthesized in the process 4 are displayed on the screen. |
