Good quality antialiasing is achieved in spite of unavoidable approximations. Compared to an ordinary z-buffer, only a little extra memory space and processing time are required. In particular, this fast method can be beneficial when used on a raster graphics system equipped with a hardware-implemented z-buffer. Our approach, however, offers appropriate treatment for certain problems left unsolved by previous methods.10.2312/egtp.19871037
