Implementation of Fuzzy Boolean operations. Such operations allow to perform Boolean operations on the shapes with near-coincidence between the entities of these shapes, i.e. between shapes in which some entities from one shape are intended to be coincide with some entities from the other, but the coincidence is not precise. API for Boolean operations has been improved to have a possibility to add new options. Modified entities: 1. New option of setting additional tolerance have been added to the following classes: class BOPAlgo_ArgumentAnalyzer class BOPAlgo_BOP class BOPAlgo_Builder class BOPAlgo_MakerVolume class BOPAlgo_PaveFiller class BOPDS_DS class BRepAlgoAPI_BooleanOperation class BRepAlgoAPI_Check class BRepAlgoAPI_Common class BRepAlgoAPI_Cut class BRepAlgoAPI_Fuse class BRepAlgoAPI_Section 2. Following draw commands have been modified to support new functionality: BOP commands: bop b1 b2 [tol] bcommon r b1 b2 [tol] bcut r b1 b2 [tol] bfuse r b1 b2 [tol] bsection r s1 s2 [-n2d/-n2d1/-n2d2] [-na] [tol] mkvolume r b1 b2 ... [-c] [-ni] [-s] [tol] bfillds [-s -t] [tol] Check commands: bopcheck Shape [level of check: 0 - 9] [-t -s] [-tol tol] bopargcheck [-F/O/C/T/S/U] [/R|F|T|V|E|I|P|C|S]] [#BF] [-tol tol] 3. Two new classes have been added to API to provide the root interface for algorithms class BRepAlgoAPI_Algo class BRepAlgoAPI_BuilderAlgo Fix to eliminate the warning. Test-cases for issue #25477

deferred class BooleanOperation from BRepAlgoAPI
|
|
inherits BuilderAlgo from BRepAlgoAPI
|
|
|
|
---Purpose: The abstract class BooleanOperation is the root
|
|
-- class of Boolean Operations (see Overview).
|
|
-- Boolean Operations algorithm is divided onto two parts.
|
|
-- - The first one is computing interference between arguments.
|
|
-- - The second one is building the result of operation.
|
|
-- The BooleanOperation class provides execution of both parts
|
|
-- of the Boolean Operations algorithm. The second part
|
|
-- (building the result) depends on given type of the Boolean
|
|
-- Operation (see Constructor).
