Abstract: A visual simulator for a spectacle lens including: a lens design data acquirer that acquires lens design data on design items of a spectacle lens including a prescription for a spectacle wearer's naked eye; a lens designer that designs the spectacle lens based on the lens design data; an original image data acquirer that acquires an original image data for the simulation; an image processor that processes the original image data acquired by the original image data acquirer and generates image data representing an image viewed through a lens processed based on the frame data; a display that comprises a screen that displays the image based on the image data generated by the image processor; a partial enlargement information acquirer that acquires partial enlargement information of a visual field, the partial enlargement information including a distance from a spectacle lens wearer to the screen of the display and a dimension of the screen, wherein a processing mode of the image processor includes: an entire dis

Abstract: A graphics system improves the efficiency in measurement operations of three-dimensional objects by enabling a user to easily and accurately specify the measurement point of the three-dimensional objects on a screen. A user can obtain the display of horizontal and vertical distances between surfaces of three-dimensional objects by specifying a point on the screen displaying the sectioned three-dimensional objects. Also, the graphics system can display three-dimensional objects whose parts are readily distinguishable by color from each other.
