The purpose of this study is to devise a suitable method of the rendering for better man-machine communication in the manipulation of pictures by computers. With this method, one can easily get an impression of 3-D shapes by pictures. In this paper, a method of the tone set-ting dither was devised. This method has the advantage of a prevention of the Mach effect which is observed in displaying a continuous tone with a low color resolution graphic display. Consequently it is able to display a curved surface with smooth shading by this method, even when a low color resolution graphic display is used. Further, the painting method is classified so as to make data input easy for picture painting. To achieve this, the partial modification method of a picture with shading on a graphic display is considered. As a result, one can interactively paint a color continuous tone. The paint system 'CARP' (Computer Aided Rendering for Presentation) that has these functions is created. Some pictures with shading were drawn using the CARP. Thus, the CARP is available not only for drawing some pictures but also many display-fields.
