PROBLEM TO BE SOLVED: To increase the degree of freedom for drawing a virtual space by generating an image showing the virtual space when the line-of-sight direction forming a visual point element is viewed from the visual point position forming an input visual point element and plating generated image on a display screen. SOLUTION: A visual point element input means 15 contains a manipulator such as a mouse, etc., opens a menu screen on a display screen 14a and clicks an icon via the operation of the mouse to display a camera set as a submenu. The icon of the camera set is clicked to show a camera set screen where the position and direction are set for a camera that projects a virtual space on the display screen. Then the prescribed position and direction are successively inputted in numerical value through a keyboard, so that a visual point element consisting of the camera position and direction is inputted to a two-dimensional image generation means 12. Based on this input visual point element, a two-dimensional image of the virtual space is generated and plotted. |
