One of the three logical operations AND, OR, and NOT, first used by George Boole, fundamental to doing searching in databases.
A Boolean object combines two objects by performing a Boolean operation on them. In the software, a Boolean object is made from two overlapping objects. The original two objects are the operands (A and B) and the Boolean object itself is the result of the operation. For geometry, the Boolean operations are: Union: The Boolean object contains the volume of both original objects. The intersecting or overlapping portion of the geometry is removed. Intersection: The Boolean object contains only the volume that was common to both original objects (in other words, where they overlapped). Subtraction (or difference): The Boolean object contains the volume of one original object with the intersection volume subtracted from it.
A 3D modeling method where one object is modeled by adding or subtracting another object from its surface. The common commands are Boolean union, Boolean subtraction, and Boolean intersection.
an operation that follows the rules of boolean algebra; each operand and the result take one of two values
a combination of comparison expressions
An operation by which bit settings are combined according to one of the 16 boolean constants that can be the argument to the Common Lisp function boole.
A boolean object is created using two objects, these can be added, subtracted, etc. from each other.
Any operation in which each of the operands take on the result of one or two possible values, TRUE or FALSE (ie: and, or, xor, exor).
Any operation where each of the operands and the result take one of two values.
Named after the logician George Boole. Boolean Operators are used in search engines and are variables which can either have a value of true or false. They are AND, OR, NOT and you can include them in your search phrases. For example, instead of expressing a wish to find out about 'the planets' you would say 'planets NOT music'.
In polygonal and NURBS modeling, a modeling method where one shape can act upon another as a volumetric tool. Boolean operations include the union, difference, and intersection logic operations, which can be applied to two solid objects to combine, remove, or keep only the intersections of their volumes. For example, a cylinder can be subtracted from a cube using the difference operation to create a cube with a hole.
