Abstract
The present invention is to output the geometric form characteristic, such as the principal curvature of a geometric model constituted in a computer to meet an image of a user to easily modify the form. In order to achieve the foregoing object, there is suggested an apparatus for displaying a geometric form characteristic that includes a form display device for displaying, on a display device such as a CRT, a geometric model input in the computer, a position instruction device for indicating, on the display screen, an arbitrary point on the displayed form by using a pointing device such as a mouse, a geometric form characteristic calculating device for calculating the geometric form characteristic at the arbitrarily indicated point, and a geometric form characteristic display device for displaying the calculated geometric form characteristic in the form of a graph. According to the present invention, a form that meets the image of a user, such as a concave, convex and the plane portion can be displayed as the user directly touches the form using a mouse.
