Title (EN) METHOD FOR EVALUATING DYNAMIC PERSPECTIVE DISTORTION OF TRANSPARENT BODY AND METHOD FOR SUPPORTING DESIGNING OF THREE-DIMENSIONAL SHAPE OF TRANSPARENT BODY
(FR) PROCEDE D'EVALUATION D'UNE DISTORTION PERSPECTIVE DYNAMIQUE D'UN CORPS TRANSPARENT, ET PROCEDE DE PRISE EN CHARGE DE LA CONCEPTION D'UNE FORME TRIDIMENSIONNELLE DU CORPS TRANSPARENT
Abstract: front page image
(EN)A method comprising the steps of creating a three-dimensional curved surface geometric model of a transparent body, determining an eye point and a virtual evaluation pattern, viewing the virtual evaluation pattern through the transparent body from the eye point so as to determine the intervals between adjacent perspective evaluation points, determining one of the intervals as a reference value, and calculating the ratio of each interval to the reference value so as to evaluate the dynamic perspective distortion of the transparent body.
(FR)L'invention concerne un procédé qui consiste à créer un modèle géométrique tridimensionnel à surface arrondie d'un corps transparent; à déterminer un point de vue et un modèle d'évaluation virtuelle pouvant être visualisé à travers le corps transparent à partir dudit point de vue, de manière à déterminer les intervalles entre des points d'évaluation de la perspective adjacents; à définir un des intervalles comme valeur de référence; et à calculer le rapport de chaque intervalle à la valeur de référence de façon à évaluer la distortion perspective dynamique du corps transparent.
