Two problems in 3-D realistic graphical techniques are discussed in detail in this paper: texturing; and the fractal method and its application to Computer Graphics. Texturing is the process of simulation of the surface details of objects on the basis of 3-D shaded pictures. There are two kinds of texturing. The first is applied to smooth surface while the second is applied to rough one. The fractal method is a new method of describing the irregular object. The writer's opinion on it is presented in the paper. The method of simulating the terrian and the processing results are given as well.
