boolean operations
Finally, the 3D integrated model was established by Boolean operations between 3D geological objects and engineering objects.
      
One challenge is to generate valid models at various LODs after an arbitrary rearrangement of features using a certain LOD criterion, because composite Boolean operations consisting of union and subtraction are not commutative.
      
Nicolog compiles a very general class of built-in constraints into equivalent sets of PCs, allowing an arbitrary mixture of integer (easily extensible to real) and Boolean operations.
      
Arithmetic expressions for switching functions are introduced through the replacement of Boolean operations with arithmetic equivalents.
      
In particular we settle two open questions of [1] concerning the derivability of inference rules for Boolean operations on the right side of multivalued dependencies.
      
Closures of linear context-free languages under Boolean operations are investigated.
      
By closing these closures under further Boolean operations we obtain several new language families.
      
One class can be characterized either as having a well-defined surface which can be approximated by planar or parametric patches or as having volume described by boolean operations on patonic solids.
      
Interactive sub systems ensure Boolean operations and compare property shapes through the 3D grid.
      
The common method for generating the octrees of complex objects, is based upon generating the octrees of several pre-defined primitives and applying Boolean operations on them.
      
With this method there is no need to generate the octrees of the primitives comprising the object nor to perform Boolean operations on them.
      
Boolean operations for solids with free-form surfaces through polyhedral approximation
      
This paper describes a new implementation method for Boolean operations between solids with free-form surfaces.
      
Boolean operations consist of two processes-topological modification and geometric modification-which are performed separately in our method.
      
Boolean operations can then be performed on this model.
      
We present a method for distributing entities of solid models in an array of processors for intersection tests in evaluating boolean operations.
      
Polygonal boundary approximation for a 2D general sweep based on envelope and boolean operations
      
We present a multiscale editor which enables Boolean operations on this domain decomposition and simply algebraic operations on the basis functions.
      
and presents interesting properties and applications like point-in-polyhedron inclusion test, computation of Boolean operations, or 3D location.
      
Boolean operations on binary images are applied when one desires to combine the information contained in several binary images.
