Abstract

Procédé de rendu 3d, comprenant la réception d'un groupe de triangles 3d définissant un maillage d'une surface, chaque triangle 3d du groupe ayant des sommets 3d avec des coordonnées 3d respectives, et transformant chaque triangle 3d en un triangle 2d ayant des sommets 2d correspondant respectivement au sommets 3d, chaque sommet 2d ayant des coordonnées de pixels 2d respectives et un triplet d'attributs de pixels correspondant aux coordonnées 3d d'un sommet 3d correspondant. Chaque triangle 2d est transmis à un processeur graphique, qui traite le triplet d'attributs de pixel de chaque sommet 2d comme des valeurs interpolables. Le processeur graphique calcule des triplets respectifs d'attributs de pixels interpolés pour des pixels dans chaque triangle 2d par interpolation entre les attributs de pixel des sommets 2d, et une image 3d de la surface est rendue en convertissant les attributs de pixels interpolés calculés par le processeur graphique en coordonnées voxel. Dans l'image 3d.
