Title:
METHOD AND DEVICE FOR ARRANGING GRAPHIC BY THREE-DIMENSIONAL COMPUTER GRAPHICS
Document Type and Number:
Japanese Patent JP3206209
Kind Code:
B2
Abstract:
PURPOSE: To easily arrange many graphics in a determined area of a graphic by arranging a graphic in a closed area at a position based upon the probability density in the closed area.
CONSTITUTION: An input device 120 inputs the graphics to be arranged in the closed area, and coordinate values and density in the closed area, a circumscribed rectangle generating device 121 generates the circumscribed rectangle from the closed area, and a random number generating device 122 generates two-dimensional random numbers in the circumscribed rectangle. An inside/ outside decision device 128 for the closed area decides whether the generated random numbers are inside or outside the closed area and inputs data in the area to a graphic arranging device 126. Further, a depth information storage device 125 stores distances to the graphics projected on a screen, pixel by pixel. Then the graphic arranging device 126 arranges the graphics in three dimensions by referring to height information corresponding to two-dimensional position information for arranging the graphics in the depth information storage device 125, thereby displaying the respective graphics as three-dimensional computer graphics by using a display device 127.
