Title
(EN) ITERATING DIFFERENT CAMERA REPRESENTATIONS IN THREE-DIMENSIONAL MODEL
(FR) ITÉRATION DE DIFFÉRENTES REPRÉSENTATIONS DE CAMÉRA DANS UN MODÈLE TRIDIMENSIONNEL
Abstract
(EN)
The evaluation of multiple virtual camera representations at the same point-of-view within a three-dimensional environment without recalculating a light travel transform that represents how light travels and reflects within the three-dimensional environment. These virtual camera representations may include a light capture transform that represents a transform from camera input to camera output. The virtual camera representation may also include a vision algorithm for interpreting the camera output. Thus, different virtual camera representations at the same point-of-view may be used to obtain a variety of representations of the three-dimensional environment at the same point-of-view.
(FR)
La présente invention a trait à l’évaluation de multiples représentations de caméra virtuelles au même point de vue dans un environnement tridimensionnel sans recalculer une transformée de déplacement de lumière qui représente la manière selon laquelle la lumière se déplace et se réfléchit dans l’environnement tridimensionnel. Ces représentations de caméra virtuelles peuvent comprendre une transformée de capture de lumière qui représente une transformée de l’entrée de la caméra à la sortie de la caméra. La représentation de caméra virtuelle peut également comprendre un algorithme de vision pour interpréter la sortie de la caméra. Ainsi, différentes représentations de caméra virtuelles au même point de vue peuvent être utilisées pour obtenir un grand nombre de représentations de l’environnement tridimensionnel au même point de vue.
