PROBLEM TO BE SOLVED: To fast draw the contact feeling between both objects when an image is generated or the texture of a contact part with some reality. SOLUTION: This method/device has a storage means 11 which stores the shape data on every object to be drawn in the computer graphics, the shape data showing a contact part between an object and another in every moving direction (+X and -X axis directions, etc.) of the object, and the line type data which point the type of an edging line 14 of the contact part between both objects, a drawing means 12 which takes the contact shape data showing the contact part of both objects and the line type data (notched lines) corresponding to both objects out of the means 11 against the calculation result obtained when an object A (rectangular parallelepiped) moves to an object B (floor) and both objects A and B touch with each other and then produces a display signal to show a visible range in an edge line of the contact part by the line 14, and a display means 13 which shows the edging based on the display signal. |
