A method and system (10) for generating a plurality of images of a three-dimensional scene from a database and a specified eye point and field of view. The method includes the steps of rendering an image frame, and warping the image frame by changing the eye point and field of view. The warping process is continued on the same image frame in accordance with a predetermined criteria, such as an evaluation of the distortion between the initial image displayed and the last image displayed for this image frame. The warping step utilizes convolution to change the eye point and field of view. The database includes a traversal vector for enabling the eye point and field of view to be determined, and a plurality of voxel elements of at least two different type.

Procédé et système (10) permettant de générer une série d'images d'une vue en trois dimensions à partir d'une base de données, d'un point de visée et d'un champ de vision spécifiques. Le procédé inclut les étapes consistant à restituer une image et à gauchir cette image en changeant le point de visée et le champ de vision. Le processus de gauchissement s'effectue de manière continue sur la même image, selon des critères prédéterminés, tels qu'une évaluation de la distortion entre l'image initiale affichée et la dernière image affichée pour cette image. Le gauchissement fait appel à la convolution pour modifier le point de visée et le champ de vision. La base de données comprend un vecteur de traversée permettant de déterminer le point de visée et le champ de vision, ainsi qu'une série d'éléments voxels d'au moins deux types différents.
