StlMesh_Mesh Class Reference

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.

Public Member Functions

Standard_EXPORT StlMesh_Mesh ()
 Creates an empty mesh.
.
virtual Standard_EXPORT void AddDomain ()
 Adds a new mesh domain. The mesh deflection is
defaulted to Confusion from package Precision.
.
virtual Standard_EXPORT void AddDomain (const Standard_Real Deflection)
 Adds a new mesh domain.
//! Raised if the deflection is lower than zero
//! Raised if the deflection is lower than Confusion
from package Precision
.
virtual Standard_EXPORT Standard_Integer AddTriangle (const Standard_Integer V1, const Standard_Integer V2, const Standard_Integer V3, const Standard_Real Xn, const Standard_Real Yn, const Standard_Real Zn)
 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.
.
virtual Standard_EXPORT Standard_Integer AddVertex (const Standard_Real X, const Standard_Real Y, const Standard_Real Z)
 Returns the range of the vertex in the current
domain.
.
virtual Standard_EXPORT Standard_Integer AddOnlyNewVertex (const Standard_Real X, const Standard_Real Y, const Standard_Real Z)
 Returns the range of the vertex in the current
domain. The current vertex is not inserted in the
mesh if it already exist.
.
virtual Standard_EXPORT void Bounds (gp_XYZ &XYZmax, gp_XYZ &XYZmin) const
 Each vertex of the mesh verifies the following
relations :
XYZMin.X() <= X <= XYZMax.X()
XYZMin.Y() <= Y <= XYZMax.y()
XYZMin.Z() <= Z <= XYZMax.Z()
.
virtual Standard_EXPORT void Clear ()
virtual Standard_EXPORT Standard_Real Deflection (const Standard_Integer DomainIndex) const
 Returns the deflection of the mesh of the domain
of range <domainindex>.
//! Raised if <domainindex> is lower than 1 or greater
than the number of domains.
.
virtual Standard_Boolean IsEmpty () const
virtual Standard_Integer NbDomains () const
 Number of domains in the mesh.
.
Standard_Integer NbTriangles () const
 Cumulative Number of triangles in the mesh.
.
virtual Standard_EXPORT Standard_Integer NbTriangles (const Standard_Integer DomainIndex) const
 Number of triangles in the domain of range
<domainindex>.
//! Raised if <domainindex> is lower than 1 or greater
than the number of domains.
.
virtual Standard_Integer NbVertices () const
 Cumulative Number of vertices in the mesh.
.
virtual Standard_EXPORT Standard_Integer NbVertices (const Standard_Integer DomainIndex) const
 Number of vertices in the domain of range
<domainindex>.
//! Raised if <domainindex> is lower than 1 or greater
than the number of domains.
.
virtual Standard_EXPORT const
StlMesh_SequenceOfMeshTriangle
Triangles (const Standard_Integer DomainIndex=1) const
 Returns the set of triangle of the mesh domain of range
<domainindex>.
//! Raised if <domainindex> is lower than 1 or greater
than the number of domains.
.
virtual Standard_EXPORT const
TColgp_SequenceOfXYZ & 
Vertices (const Standard_Integer DomainIndex=1) const
 Returns the coordinates of the vertices of the
mesh domain of range <domainindex>. {XV1, YV1,
ZV1, XV2, YV2, ZV2, XV3,.....}
//! Raised if <domainindex> is lower than 1 or greater
than the number of domains.
