Title (EN) INDEXING VOXELS FOR 3D PRINTING
(FR) INDEXATION DE VOXELS POUR IMPRESSION 3D
Abstract:
(EN) One example includes a non-transitory machine readable storage medium including voxels organized by an octree and at least one quad-tree index. The octree defines an object to be three-dimensionally printed and includes a list of nodes for each depth of the octree where each node includes nodal content representing at least one voxel. The at least one quad-tree index is to index at least one node of the octree and has a depth less than or equal to a maximum resolved depth. The at least one quad-tree index is to be accessed by computer executable instructions to retrieve nodal content from the octree to control a processor to process the object to be three-dimensionally printed.
(FR) Selon l'invention, dans un exemple, un support de stockage lisible par machine non transitoire comprend des voxels organisés par un arbre d'octants et au moins un indice d'arbre de quadrants. L'arbre d'octants définit un objet à imprimer en trois dimensions et comprend une liste de nœuds pour chaque profondeur de l'arbre d'octants, chaque nœud comprenant un contenu nodal représentant au moins un voxel. Ledit au moins un indice d'arbre de quadrants est destiné à indexer au moins un nœud de l'arbre d'octants et présente une profondeur inférieure ou égale à une profondeur résolue maximale. Des instructions exécutables par ordinateur doivent pouvoir accéder à ou aux indices d'arbre de quadrants pour récupérer le contenu nodal de l'arbre d'octants afin de donner à un processeur l'instruction de traiter l'objet à imprimer en trois dimensions.
