1.The algorithm builds BoxTreees of arbitrary non convex polyhedra using a hierarchical adaptive space subdivision scheme,and speeds up collision detection by traversing the BoxTrees in parallel.该算法面向动态复杂场景采用层次的自适应空间剖分方法建构物体的平衡包围盒树,然后通过并行遍历包围盒树来加速碰撞...
The hierarchical bounding box - tree was built by dividing the polyhedron into tetrahedron. The collision detection can be completed by the method searching the bounding box-tree from top to bottom or from bottom to top. The algorithm quickly eliminated the possibility of collision between objects ...

The tree of subdivision gets bushier and time is wasted on exploring paths which do not contribute to the result. The theorem which is being used implicitly here is that every point in the convex hull is also in the bounding box. This is simply proved by observing that every point in ...
You can create a bounding box feature in an assembly that contains geometry. The bounding box is calculated by using the same methods as the part-level bounding box.An assembly can contain only one Bounding Box feature. In the FeatureManager® design tree, you can right-click the bounding ...

将分割的label图转换为目标检测boundingbox标注文件(VOC格式)。 注: 1.分割样本里一张图片只有同一类别的多个目标。 2.转换为boundingbox标注通过连通域实现,所以重叠的目标处理不了,会标为1个。 数据集格式 其中,语义分割数据集格式如下: 原图片在JPEGImages文件夹中,命名格式为ImageID.jpg ...
Each node v in the tree corresponds to a subset Sv (Sv⊆S) of S. 2. The bounding box b(Sv) of the set Sv is also associated with each node v. 3. The root node corresponds to the bounding box b(S) of the complete set S and S. 4. Each inner node (nonleaf node) in the...
