Title
(EN) SERIALISING A REPRESENTATION OF A THREE DIMENSIONAL OBJECT
(ZH) 使三维对象的表示序列化
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) nodesrepresenting 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.
(ZH) 在示例中,一种方法包括在处理器处接收表示要在逐层制造过程中制造的对象的至少一部分的数据。可以从所述数据生成所述对象的至少一部分的序列化八叉树表示。在所述序列化八叉树表示中,节点被排序为使得(i)表示包括要按照对象生成的预定顺序较早地生成的所述对象的层的体积的节点在表示由要随后生成的所述对象的(一个或多个)层构成的体积的节点之前;(ii)表示包括所述对象的给定层的体积的节点基于所述八叉树表示内的所述节点的级被排序,其中父节点出现在后代节点之前;以及(iii)表示包括所述对象的给定层并在所述八叉树表示内具有相同级的体积的节点根据位置编码图案被排序。
