Abstract
(EN)
A programmable pipeline for synthesis of multi-material 3D printed objects supports procedural evaluation of geometric detail and material composition, using program modules allowing models to be specified easily and efficiently. A streaming architecture enables only a small fraction of the final volume to be stored in memory. Output is fed to the printer with little startup delay. A variety of multi-material objects are described. Procedural control over surface and volume stages as well as dithering is provided, together or independent of each other.
(FR)
Un pipeline programmable servant à la synthèse d'objets imprimés en 3D composés de plusieurs matériaux prend en charge une évaluation procédurale des détails géométriques et de la composition des matériaux, à l'aide de modules de programme permettant de spécifier facilement et efficacement des modèles. Une architecture de flux continu permet de ne stocker en mémoire qu'une petite fraction du volume final. La sortie est fournie à l'imprimante avec un léger retard de démarrage. Un grand nombre d'objets composés de plusieurs matériaux sont décrits. La présente invention permet une commande procédurale sur des phases de surface et de volume ainsi qu'un tramage, conjointement ou indépendamment l'un à l'autre.
