A method of forming 3D graphics for interactive digital broadcasting and a system of forming 3d graphics using the method are provided to improve processing speed by removing a back face of a 3D object, selecting a second information composing a visual screen and computing the second information. A method of forming 3d graphics for interactive digital broadcasting includes the steps of: judging whether a 3D object is transparent or not; if the 3D object is transparent, performing rendering on the basis of a first information composing the 3D object; if the 3D object is not transparent, performing rendering on the basis of a second information composing a visible screen of the 3D object; and reading out a back face of the 3D object, and removing the back face to determine the visible screen. |
