  2. Open Cascade Technology - Wikipedia

    en.wikipedia.org/wiki/Open_Cascade_Technology

    The Open CASCADE IFC Import SDK provides applications with the capability of reading building information modeling (BIM) data from files in Industry Foundation Classes (IFC) format. It supports versions IFC2×3 and IFC4 that used by most modern applications. [26] This allows visualizing and manipulating building geometries and CAD designs.

  3. Minimum bounding rectangle - Wikipedia

    en.wikipedia.org/wiki/Minimum_bounding_rectangle

    A series of geometric shapes enclosed by its minimum bounding rectangle. In computational geometry, the minimum bounding rectangle (MBR), also known as bounding box (BBOX) or envelope, is an expression of the maximum extents of a two-dimensional object (e.g. point, line, polygon) or set of objects within its x-y coordinate system; in other words min(x), max(x), min(y), max(y).

  4. R-tree - Wikipedia

    en.wikipedia.org/wiki/R-tree

    The key idea is to use the bounding boxes to decide whether or not to search inside a subtree. In this way, most of the nodes in the tree are never read during a search. Like B-trees, R-trees are suitable for large data sets and databases, where nodes can be paged to memory when needed, and the whole tree cannot be kept in main memory. Even if ...

  5. Minimum bounding box algorithms - Wikipedia

    en.wikipedia.org/wiki/Minimum_bounding_box...

    In computational geometry, the smallest enclosing box problem is that of finding the oriented minimum bounding box enclosing a set of points. It is a type of bounding volume. "Smallest" may refer to volume, area, perimeter, etc. of the box. It is sufficient to find the smallest enclosing box for the convex hull of the objects in question. It is ...

  6. Minimum bounding box - Wikipedia

    en.wikipedia.org/wiki/Minimum_bounding_box

    A sphere enclosed by its axis-aligned minimum bounding box (in 3 dimensions) In geometry, the minimum bounding box or smallest bounding box (also known as the minimum enclosing box or smallest enclosing box) for a point set S in N dimensions is the box with the smallest measure (area, volume, or hypervolume in higher dimensions) within which all the points lie.

  7. Quadtree - Wikipedia

    en.wikipedia.org/wiki/Quadtree

    Build a quadtree on the input points. Ensure the quadtree is balanced. For every leaf, if there is a neighbour that is too large, subdivide the neighbour. This is repeated until the tree is balanced. We also make sure that for a leaf with a point in it, the nodes for each leaf's extended cluster are in the tree.

  8. Bounding volume - Wikipedia

    en.wikipedia.org/wiki/Bounding_volume

    Unfortunately, intersection tests become quickly more expensive as the bounding boxes become more sophisticated. A bounding box or minimum bounding box (MBB) is a cuboid, or in 2-D a rectangle, containing the object. In dynamical simulation, bounding boxes are preferred to other shapes of bounding volume such as bounding spheres or cylinders ...

  9. Compactness measure - Wikipedia

    en.wikipedia.org/wiki/Compactness_measure

    Alternatively, the shape's area could be compared to that of its bounding circle, [1] [2] its convex hull, [1] [3] or its minimum bounding box. [3] Similarly, a comparison can be made between the perimeter of the shape and that of its convex hull, [3] its bounding circle, [1] or a circle having the same area. [1]
