Title (EN) SYSTEM AND METHOD FOR EFFICIENTLY DETERMINING A BLEND VALUE IN PROCESSING GRAPHICAL IMAGES
(FR) SYSTEME ET PROCEDE PERMETTANT DE DETERMINER EFFICACEMENT UNE VALEUR DE MELANGE DANS LE TRAITEMENT D'IMAGES GRAPHIQUES
Abstract:
(EN) A system for generating blend values (18) for three-dimensional graphic rendering includes a first register (12), a second register (14), a third register (15), and index creation unit (16), a blend value generation unit (18) and a blending unit (20). The first register receives and stores color pixel data, the second register receives and stores a depth perspective component, and the third register receives and stores fog color data.
(FR) L'invention porte sur un système de génération de valeurs de mélange (18) pour le rendu graphique en trois dimensions, comprenant un premier registre (12), un deuxième registre (14) et un troisième registre (15), une unité de création d'indices (16), une unité de génération de valeurs de mélange (18), et une unité de mélange (20). Le premier registre reçoit et stocke les données relatives aux pixels de couleur, le deuxième reçoit et stocke un composant de profondeur de perspective, et le troisième reçoit et stocke les données relatives aux lointains en couleur.
