Abstract: A real-time rendering method of a three-dimensional object comprising the following phases: performing the rendering of the substantially opaque elements by realizing at least one first image, performing a plurality of sequential steps, wherein the transmissive elements are rendered from the furthest to the closest to the virtual video/photo-camera according to a predetermined ordered list by realizing a respective plurality of second images, where in the first step transmissive elements furthest away from the virtual video/photo-camera are rendered using the at least one first image to determine the spectrum of the light directed towards the virtual video/photo-camera coming from the transmissive elements to be rendered, and where in each step i one or more transmissive elements are rendered using the second image obtained in the immediately preceding step to determine the spectrum of the light directed towards the virtual video/photo-camera coming from the transmissive elements to be rendered.

Abstract: Method for shooting and editing a film comprising at least one image of a 3D computer-generated animation created by a cinematographic software according to mathematical model of elements that are part of the animation and according to a definition of situations and actions occurring for said elements as a function of time, said method being characterized by comprising the following: computing of alternative suggested viewpoints by the cinematographic software for an image of the 3D computer-generated animation corresponding to a particular time point according to said definition; and instructing for displaying on a display interface, all together, images corresponding to said computed alternative suggested viewpoints of the 3D computer-generated animation at that particular time point.
