class ShellFaceClassifier from TopOpeBRepBuild

inherits CompositeClassifier from TopOpeBRepBuild
|
|
|
|
---Purpose:
|
|
-- Classify faces and shells.
|
|
-- shapes are Shells, Elements are Faces.

Create(BB : BlockBuilder) returns ShellFaceClassifier;
|
|
---Purpose: Creates a classifier in 3D space, to compare :
|
|
-- a face with a set of faces
|
|
-- a shell with a set of faces
|
|
-- a shell with a shell

---Purpose: classify shell <B1> with shell <B2>
|
|
returns State from TopAbs;

|
|
---Purpose: classify face <F> with shell <S>

|
returns State from TopAbs;

|
|
---Purpose: prepare classification involving shell <S>
|
|
-- calls ResetElement on first face of <S>
|
|
|
|
ResetElement(me : in out; F : Shape);
|
|
---Purpose: prepare classification involving face <F>
|
|
-- define 3D point (later used in Compare()) on first vertex of face <F>.
|
|
|
|
CompareElement(me : in out; F : Shape)
|
|
returns Boolean from Standard;
|
|
---Purpose: Add the face <F> in the set of faces used in 3D point
|
|
-- classification. Returns FALSE if the face <F> has been already
|
|
-- added to the set of faces, otherwise returns TRUE.
|
|
|
|
|
|
State(me : in out) returns State from TopAbs;
|
|
---Purpose: Returns state of classification of 3D point, defined by
|
|
-- ResetElement, with the current set of faces, defined by Compare.
