Title
(EN) SUB-VOLUME OCTREES
(ZH) 子体积八叉树
Abstract
(EN) In an example, a method includes receiving a first data model of an object to be generated in additive manufacturing, at a processor. Using the processor, a second data model may be determined. Determining the second data model may include generating for each of plurality of contiguous, non-overlapping sub-volumes of a volume containing the object, a sub-volume octree characterising the sub-volumeand having a root node. Determining the second data model may further include generating a volume octree characterising the volume containing the object, the volume octree characterising in its lowest nodes the root nodes of the sub-volume octrees.
(ZH) 在示例中,一种方法包括在处理器处接收要在增材制造中生成的对象的第一数据模型。使用所述处理器,可以确定第二数据模型。确定所述第二数据模型可以包括针对包含所述对象的体积的多个连续的非重叠子体积中的每一个,生成表征所述子体积并具有根节点的子体积八叉树。确定所述第二数据模型可以进一步包括生成表征包含所述对象的所述体积的体积八叉树,所述体积八叉树在其最低节点中表征所述子体积八叉树的所述根节点。
