	Bounding Box (Site not responding. Last check: 2007-10-20)
		The bounding box of a PostScript image -- the printable figures and text on a page -- is the tightest rectangle which includes the image when the PostScript file is printed.
		The bounding box is described by 4 numbers; the x-y coordinates of the lower-left corner of the image, followed by the x-y coordinates of the upper-right corner of the image.
		Thus for images on an 8.5"×11" page, the x -coordinates of the bounding box always lie between 0 and 612, while the y -coordinates of the bounding box always lie between 0 and 792.

	Generation of 3D Anatomy Based Dose Points in Brachytherapy
		The ratio of the number of points inside the structure to the number of points inside the associated bounding box, which is maximal for minimum bounding boxes, is equal to the ratio of the structure volume to the bounding box volume.
		The dimension of the bounding box along an axis (eigenvector) is given by the extreme values of the projection of the points on the corresponding axis.
		Since the actual minimum bounding box volume for the implants is not known we used a test set of points with a known minimum bounding box.

	Journal of Manufacturing Systems: Bounding Box Techniques to Initialize Optimization of Primitive Geometry Fitting
		One of the fundamental assumptions of using bounding boxes for initial estimates of primitives is that the point cloud covers the extent of the entire primitive.
		The minimum bounding box method for initial guessing is applied with the same assumptions as the axis-aligned bounding box, except for the last assumption that the point cloud be principally aligned.
		A bounding box is the box that is inscribed by the point cloud-that is, each of the faces of the box is located at a maximum or minimum of the point cloud coordinates, in the direction normal to that face.

	Bounding Box Approach
		The bounding box insertion method selects proposed cohesive edges by first categorizing the system by three main regions (Figure 2.22): a non-cohesive region where no cohesive element is present, a passive cohesive region where cohesive elements are present but have not undergone any failure, and an active cohesive region where cohesive elements are failing.
		The region between the original and new bounding boxes is the passive cohesive region where failure is expected to occur in the near future.
		The bounding box method is quite capable of determining the appropriate cohesive regions although this method is not self-starting.

		The fit is generally better than a bounding sphere (especially if the object you are bounding is a box itself).
		However, once you rotate the object a little, the bounding box may not be nearly as efficient, as you can see in Figure 2.
		Calculating a bounding box for a model with many vertices is a fairly expensive process.

		The origin of a bounding box may not be at the lower left corner of the bounding box because some letters in a Latin font, like 'g', 'j', 'Q', etc., have "descenders" extending below the baseline.

	Alexandria Digital Library Project - [#GAZ-31] incorrect encoding of GML bounding box (Site not responding. Last check: 2007-10-20)
		In internal bounding box descriptions, within our database and in our middleware software, we distinguish east from west, so it's possible to describe a bounding box that crosses the +/-180 meridian: just make east less than west.
		Thus a GML bounding box is incapable of crossing the +/-180 meridian (pretty lame, IMHO, but there you have it).
		So if an internal bounding box crosses the +/-180 meridian, the only choice is to convert it to a whole-world band (i.e., -180..180).

	Bounding Containers
		It is often useful to have a bounding container (BC), such as a bounding box or ball, for a finite geometric object.
		A " box " is a rectangular region whose edges are parallel to the coordinate axes, and is thus defined by its maximum and minimum extents for all axes.
		The bounding box is the computationally simplest of all linear bounding containers, and the one most frequently used in many applications.

		A drawback of using an axis-aligned bounding box is that it can’t fit rotating geometry very tightly.
		On the other hand, an oriented bounding box can be rotated with the objects, fitting the geometry with less volume than an AABB.
		The boxes A and B are disjoint if none of the 6 principal axes and their 9 cross products form a separating axis.

	Postscript Bounding Box
		Specify whether the bounding box generated by Dataplot Postscript output will be "fixed" or "floating".

		Since encapsulated assumes that each graph will be in a separate file, it already sets the bounding box according to the orientation.

		After a model is read, the bounding box is computed from the extent of surfaces and cell bounding boxes based on the cell descriptions.
		When the geometry is being created or modified, the bounding box is increased to accommodate new and changes in surfaces, bodies, and cells.
		Some cases require explicit definition of the bounding box before a cell can be polygonalized, such as a cell bounded by a cone and a P, PXY, PXZ, or PYZ plane.

		The line bounding box" for the elements of the graphic.
		In the following example, the SVG file is establishing the boundaries of the image, by stating that in a rectangular space, the upper lefthand x, y coordinates are to be set as 0, 0 and the width and height of the viewing area are 300 and 200.
		By making the bounding box area smaller, the image can be "cropped" or "pre-zoomed." If the above numbers were changed to 100 75 100 50, the image would look like this:

	Bounding Box (Site not responding. Last check: 2007-10-20)
		Every well-formed PostScript file has a comment describing where on the page the graphic is located, and how big that graphic is. This information is given in terms of the lower left and upper right corners of a box just enclosing the graphic, and is thus referred to as a bounding box.
		the file is still probably Encapsulated PostScript, but the bounding box (that dvips needs to position the graphic) is at the end of the file and should be moved to the position of the line above.
		If the document does not have such a bounding box, or if the bounding box is given at the end of the document, please complain to the authors of the software package that generated the file; without such a line, including PostScript graphics can be tedious.
