class Mesh from StlMesh inherits TShared from MMgt
---Purpose: Mesh definition. The mesh contains one or several
-- domains. Each mesh domain contains a set of
-- triangles. Each domain can have its own deflection
-- value.
--
uses
XYZ from gp,
SequenceOfMeshDomain from StlMesh,
SequenceOfMeshTriangle from StlMesh,
SequenceOfXYZ from TColgp
raises
NegativeValue from Standard,
NullValue from Standard,
NoSuchObject from Standard
is
Create returns mutable Mesh;
---Purpose: Creates an empty mesh.
AddDomain (me : mutable) is virtual;
---Purpose: Adds a new mesh domain. The mesh deflection is
-- defaulted to Confusion from package Precision.
AddDomain (me : mutable; Deflection : Real)
---Purpose: Adds a new mesh domain.
raises NegativeValue,
---Purpose: Raised if the deflection is lower than zero
NullValue
---Purpose: Raised if the deflection is lower than Confusion
-- from package Precision
is virtual;
AddTriangle (me : mutable; V1, V2, V3 : Integer; Xn, Yn, Zn : Real)
returns Integer
---Purpose: Build a triangle with the triplet of vertices (V1,
-- V2, V3). This triplet defines the indexes of the
-- vertex in the current domain The coordinates Xn,
-- Yn, Zn defines the normal direction to the
-- triangle. Returns the range of the triangle in
-- the current domain.
is virtual;
AddVertex (me : mutable; X, Y, Z : Real) returns Integer is virtual;
---Purpose: Returns the range of the vertex in the current
-- domain.
AddOnlyNewVertex (me : mutable; X, Y, Z : Real) returns Integer
---Purpose: Returns the range of the vertex in the current
-- domain. The current vertex is not inserted in the
-- mesh if it already exist.
is virtual;
Bounds (me; XYZmax, XYZmin : in out XYZ) is virtual;
---Purpose: Each vertex of the mesh verifies the following
-- relations :
-- XYZMin.X() <= X <= XYZMax.X()
-- XYZMin.Y() <= Y <= XYZMax.y()
-- XYZMin.Z() <= Z <= XYZMax.Z()
Clear (me : mutable) is virtual;
Deflection (me; DomainIndex : Integer) returns Real
---Purpose: Returns the deflection of the mesh of the domain
-- of range <DomainIndex>.
raises NoSuchObject
---Purpose: Raised if <DomainIndex> is lower than 1 or greater
-- than the number of domains.
is virtual;
IsEmpty (me) returns Boolean is virtual;
---C++: inline
NbDomains (me) returns Integer is virtual;
---Purpose: Number of domains in the mesh.
---C++: inline
NbTriangles (me) returns Integer;
---Purpose: Cumulative Number of triangles in the mesh.
---C++: inline
NbTriangles (me; DomainIndex : Integer) returns Integer
---Purpose: Number of triangles in the domain of range
-- <DomainIndex>.
raises NoSuchObject
---Purpose: Raised if <DomainIndex> is lower than 1 or greater
-- than the number of domains.
is virtual;
NbVertices (me) returns Integer
---Purpose: Cumulative Number of vertices in the mesh.
---C++: inline
is virtual;
NbVertices (me; DomainIndex : Integer) returns Integer
---Purpose: Number of vertices in the domain of range
-- <DomainIndex>.
raises NoSuchObject
---Purpose: Raised if <DomainIndex> is lower than 1 or greater
-- than the number of domains.
is virtual;
Triangles (me; DomainIndex : Integer = 1) returns SequenceOfMeshTriangle
---Purpose: Returns the set of triangle of the mesh domain of range
-- <DomainIndex>.
---C++: return const &
raises NoSuchObject
---Purpose: Raised if <DomainIndex> is lower than 1 or greater
-- than the number of domains.
is virtual;
Vertices (me; DomainIndex : Integer = 1) returns SequenceOfXYZ from TColgp
---Purpose: Returns the coordinates of the vertices of the
-- mesh domain of range <DomainIndex>. {XV1, YV1,
-- ZV1, XV2, YV2, ZV2, XV3,.....}
---C++: return const &
raises NoSuchObject
---Purpose: Raised if <DomainIndex> is lower than 1 or greater
-- than the number of domains.
