Abstract

A computer graphics apparatus includes a walk-through function to simulate with a computer the concept of walking through a structure such as a building. Display processing time and calculation processing time for one frame of a computer graphic image are improved by an input unit which receives a viewline moving instruction to move a viewline of a computer image. A viewline control unit determines positions and directions of the viewline while a storage unit stores computer graphics data including three-dimensional data of objects, walk-through attribute data and viewline data. An image generation unit then generates images including animated images based on the position of the viewline and the computer graphics data. The resultant images are then displayed on an image display unit.
