Abstract

L'appareil de l'invention comprend une mémoire-tampon tridimensionnelle (438); un bus à pixels (442); plusieurs pipelines de rendu (440); et une unité de commande (454). Chaque pipeline de rendu comprend une première unité à tranches (544); une unité de composition d'images (464); un tampon de composition bidimensionnelle par tranche (474); et une première unité d'interpolation (472 ou 546). Les valeurs des points échantillons sont combinées aux pixels du tampon de composition d'images, le long de plusieurs segments de rayon intertranche (410) qui s'étendent seulement entre une tranche en cours contenue dans l'unité à tranches et une tranche contenue dans le tampon de composition d'images bidimensionnelle par tranche. Les gradients sont également calculés au niveau des positions des voxels, ce qui améliore la précision.
