论文摘要
查询和与大型材料微观结构模型进行互动，需要微观结构的按需局部生成，因为全尺度存储和检索是成本较高的。当微结构有效地表示为非线性空间变形下的规范结构的图像以使其能够符合弯曲形状时，另一个挑战是将映射的微结构的查询与其规范结构相关联。本文提出了一种有效的算法，可以将映射的微结构向后拉到规范域结构的分区中，仅激活其图像可能与平面相交的框。活跃的盒子被组织成一片森林，其树木首先穿过深度，以生成仅在活动盒中的映射微结构。遍历的支持，例如在增材制造中生成3D打印片。
Querying and interacting with models of massive material micro-structure requires localized on-demand generation of the micro-structure since the full-scale storing and retrieving is cost prohibitive. When the micro-structure is efficiently represented as the image of a canonical structure under a non-linear space deformation to allow it to conform to curved shape, the additional challenge is to relate the query of the mapped micro-structure back to its canonical structure. This paper presents an efficient algorithm to pull back a mapped micro-structure to a partition of the canonical domain structure into boxes and only activates boxes whose image is likely intersected by a plane. The active boxes are organized into a forest whose trees are traversed depth first to generate mapped micro-structure only of the active boxes. The traversal supports, for example, 3D print slice generation in additive manufacturing.
