Title:
GRAPHICS DEVICE
Document Type and Number:
Japanese Patent JP3739852
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To speed up three-dimensional graphics output by previously making parameters including a viewpoint position and a sight direction correspond to an object.
SOLUTION: A viewpoint position determining means 1 obtains the viewpoint position and a sight direction determining means 2 obtains the sight direction. A parameter extracting means 11 extracts parameters including a combination of the obtained viewpoint position and sight direction and sends them to an object extracting means 12. Further, a three-dimensional position determining means 3 sends an object structure data request corresponding the extracted parameters. Then an object extracting means 12 obtains object structure data (three-dimensional structure data) from object structure data storage corresponding to the extracted parameters. Further, a three-dimensional position determining means 3 determines the three-dimensional position of the object. Further, a two-dimensional image generating means 4 generates a two-dimensional image from the object structure data. After a loop ends, the generated image is drawn by an image drawing means 5 and outputted on a display 6.
