In computer graphics and computational geometry, a bounding volume for a set of objects is a closed volume that completely contains the union of the objects in the set. Bounding volumes are used to improve the efficiency of geometrical operations by using simple volumes to contain more complex objects. Normally, simpler volumes have simpler ways to test for overlap.

rdfs:comment	Ein Hüllkörper (englisch bounding volume) ist in der algorithmischen Geometrie ein einfacher geometrischer Körper, der ein komplexes dreidimensionales Objekt oder einen komplexen Körper umschließt. (de) Dans les domaines de la synthèse d'image et de la géométrie algorithmique, un volume englobant pour un ensemble d'objets est un volume fermé qui contient entièrement l'union de l'ensemble des objets. Les volumes englobants sont utilisés pour améliorer l'efficacité des opérations géométriques en utilisant des volumes simples, qui contiennent des objets beaucoup plus complexes. Normalement, plus un volume est simple plus le test de chevauchement est simple. (fr) 在计算机图形学与计算几何领域，一组物体的包围体就是将物体组合完全包容起来的一个封闭空间。将复杂物体封装在简单的包围体中，就可以提高几何运算的效率。通常简单的物体比较容易检查相互之间的重叠。一组物体的包围体也是包含一个物体及周围相关环境的封闭空间，因此可以用它来表示一个非空、有限的单一物体。 (zh) In computer graphics and computational geometry, a bounding volume for a set of objects is a closed volume that completely contains the union of the objects in the set.

(en) Bryła brzegowa (ang. Bounding Volume, objętość ograniczająca, BV) – bryła w uproszczony sposób przedstawiająca jak najmniejszą przestrzeń, w której całkowicie mieszczą się określone obiekty. Używa się ich, np. aby uprościć wykrywanie kolizji oraz sprawdzić widoczność na ekranie zawartych w nich obiektów, dlatego że wykorzystując uproszczone bryły można dużo szybciej i prościej wykonać potrzebne sprawdzenia. (pl) Обмежувальна коробка (англ. bounding box) — це паралелепіпед зі сторонами, паралельними осям координат, що обмежує деякий геометричний об'єкт в просторі. При обертанні об'єкта паралелепіпед зберігає свою орієнтацію, однак може змінювати свої розміри. Активно використовується в програмуванні (наприклад в фізичних рушіях різних ігор) для пошуку перетинань, зіткнень різних об'єктів між собою. (uk)

has abstract	Ein Hüllkörper (englisch bounding volume) ist in der algorithmischen Geometrie ein einfacher geometrischer Körper, der ein komplexes dreidimensionales Objekt oder einen komplexen Körper umschließt. (de) In computer graphics and computational geometry, a bounding volume for a set of objects is a closed volume that completely contains the union of the objects in the set. Bounding volumes are used to improve the efficiency of geometrical operations by using simple volumes to contain more complex objects. Normally, simpler volumes have simpler ways to test for overlap. A bounding volume for a set of objects is also a bounding volume for the single object consisting of their union, and the other way around. Therefore, it is possible to confine the description to the case of a single object, which is assumed to be non-empty and bounded (finite). (en)
