Title
(EN) SERIALISING A REPRESENTATION OF A THREE DIMENSIONAL OBJECT
(FR) SÉRIALISATION D'UNE REPRÉSENTATION D'UN OBJET TRIDIMENSIONNEL
Abstract
(EN) In an example, a method includes receiving, at a processor, data representing at least part of an object to be manufactured in a layer-by-layer manufacturing process. A serialised octree representation of at least part of the object may be generated from the data. In the serialised octree representation, nodes are ordered such that (i) a node representing a volume which includes a layer of the object to be generated earlier in an intended order of object generation precedes a node representing a volume which consists of layer(s) of the object to be generated subsequently; (ii) nodes representing a volume which includes a given layer of the object are ordered based on a level of the nodes within the octree representation, wherein parent nodes appear before descendent nodes; and (iii) nodes representing a volume which includes a given layer of the object and being of the same level within the octree representation are ordered according to a location encoding pattern.
(FR) Dans un exemple, un procédé consiste à recevoir, au niveau d'un processeur, des données représentant au moins une partie d'un objet à fabriquer au cours d'un processus de fabrication couche par couche. Une représentation par arbres d'octants sérialisée d'au moins une partie de l'objet peut être générée à partir des données. Dans la représentation par arbres d'octants sérialisée, des nœuds sont ordonnés de sorte (i) qu'un nœud représentant un volume qui comprend une couche de l'objet à générer plus tôt dans un ordre prévu de génération d'objet précède un nœud représentant un volume qui consiste en une ou plusieurs couches de l'objet à générer par la suite; (ii) que des nœuds représentant un volume qui comprend une couche donnée de l'objet sont ordonnés sur la base d'un niveau des nœuds à l'intérieur de la représentation par arbres d'octants, les nœuds parents apparaissant avant les nœuds descendants; et (iii) que des nœuds représentant un volume qui comprend une couche donnée de l'objet et étant du même niveau à l'intérieur de la représentation par arbres d'octants sont ordonnés selon un motif de codage d'emplacement.
