摘要： The invention concerns a method for compressing digital data of a sequence of computer synthesised images describing a scene subject of a script, comprising a processing step (1, 11) for modelling the scene on the basis of mathematical data, a step of image rendering for creating a synthesised image from this modelling and storyboarding in blocks of images of this synthesised image (2, 12), a differential coding of the current image block from a block of at least one synthesised image defined on the basis of at least one motion vector for supplying a residual block (4i). The invention is characterised in that the motion vector is computed from mathematical data derived from the synthesised script and defining the apparent motion of the different objects constituting the scene subject of the sequence. The invention is useful for synthesising images in production. For video games, it is useful for interaction or for producing virtual reality.

摘要： The image generating process is carried out by calculating deplacements vectors representing the evolution of an image (Z, D) to the next directly from coordinates and coefficients of geometrical transformation of points associated in the scene in 3D. The applications concern the generation of monocular sequences by temporal interpolation and stereoscopic sequences by extrapolation.

摘要： The process for generating synthesis images comprises the projection of facets of the scene in 3D on a sphere (7) whose center is the observation point and whose surface has been cut particularly in elementary areas associated to the pixels of the image (10), said cutout being carried out in such a way that the orthogonal projections of said areas on a reference plane passing through the observation point and perpendicular to the scene view axis have the same value. The applications concern the generation of distance or visibility images, the radiosity.
摘要翻译：用于产生合成图像的过程包括在其中心是观察点并且其表面已被切割的球体（7）上的3D场景的投影特别是在与图像（10）的像素相关联的基本区域中，所述球体进行切割，使得通过观察点并垂直于场景视轴的参考平面上的所述区域的正交投影具有相同的值。应用涉及距离或可见度图像的产生，辐射度。
