Abstract
A three-dimensional graphic system includes a scene origination equipment, a rendering apparatus and a display device. The user interface unit of the scene origination equipment displays on the display screen of the display device. The user interface unit of the scene origination equipment displays on the display screen of the display device a graph which represents the relationship between a distance from a point generated with a cursor and the density of the generated point. The setting of the shape of the displayed graph is accepted on the display screen, and the relationship between the distance from the generated point of the cursor and the density of the generated point is determined in accordance with the accepted setting of the shape of the graph. The image generation unit of the scene origination equipment displays the cursor on the display screen, and generates an image in which the point generated with the cursor and points vicinal to the generated point are drawn at densities conforming to the determined relationship. The rendering apparatus generates a video graphic in which the generated image is mapped on an object and displays the video graphic on the display screen.
