Apparatus for displaying a three dimensional object which appears substantially the same in different display directions by modifying stored image data by a scale factor

摘要

Image data including depth data on a pixel basis representing a sphere or column are previously generated and stored in a mapping memory. When the sphere or column is to be displayed on a display screen, the image data are read out from the mapping memory. The image data thus read out are mapped to a predetermined region of a memory for display and are processed for hidden surface removal simultaneously.
