| Abstract: | The depth-of-field effect can improve the realistic sense of a computer-generated image,and thus rendering of this effect has become one of the important research topics in computer graphics.Aiming at the problem for rendering the depth-of-field effect,in this paper we first study optical imaging principles which various kinds of camera lens models featuve,and compare their characteristics and capabilities of modeling the depth-of-field effect;then the taxonomy of rendering techniques for the depth-of-filed effect is presented.Relevant fundamental principles and typical algorithms are concluded,and their advantages and disadvantages are compared in detail.Lastly applications of rendering techniques for the depth-of-filed effect are presented and future research trends are foreseen. |
