Detailed Description

MeshViz Defines a mesh of tetrahedrons.

Class to define an indexed 3D mesh made up of tetrahedrons. This mesh is defined by a list of tetrahedrons. Each tetrahedron is defined by 4 indices of nodes.

The nodes coordinates are defined by 3 arrays x_nod, y_nod, z_nod of num_nodes floats. The tetrahedrons are defined by the array tetrahedron_index of num_tetrahedrons*4 integers. tetrahedron_index[(n*4)+p] is the p-th node index of the n-th tetrahedron of the mesh (0 <= p <= 3). Each tetrahedron must be numbered by repecting the following rule : the 3 first indices define a facet of the tetrahedron and orient it towards the interior of the tetrahedron.

Each facet of a tetrahedron may have 2 references in the mesh, that is, one facet is common to 2 tetrahedrons. The facets which are referred to once in the mesh define the mesh skin.

The values on the mesh nodes are defined by the PbMesh::addValuesSet(set_index,val) method, where val argument is an array of num_nodes floats.


Constructor & Destructor Documentation

PbTetrahedronMesh3D::PbTetrahedronMesh3D ( SbBool  isDataDuplicate = TRUE  ) 

Constructor of a default simple mesh.

See also PbMesh for more explanations about data duplication.

PbTetrahedronMesh3D::PbTetrahedronMesh3D ( const PbTetrahedronMesh3D mesh  ) 

Copy constructor.

PbTetrahedronMesh3D::PbTetrahedronMesh3D ( int  num_nodes,
const float *  x_nod,
const float *  y_nod,
const float *  z_nod,
int  num_tetrahedrons,
const int *  tetrahedron_index,
SbBool  is_data_duplicate = TRUE 
)

Constructor of a volume mesh.

Member Function Documentation

virtual const PbCell* PbTetrahedronMesh3D::getCell ( int  cell_index  )  const [virtual]

Gets the cell which index is cell_index.

Returns NULL if the cell does not exist or if it is incorrect (flat), otherwise returns always a PbTetrahedronCell object. Attention! this method returns always the same adress of an internal private cell. This private cell is updated each time getCell is called.

Reimplemented from PbIndexedMesh3D.

virtual SoDEPRECATED void PbTetrahedronMesh3D::getGeometry ( int &  num_nodes,
const float *&  x_nod,
const float *&  y_nod,
const float *&  z_nod,
int &  num_tetrahedrons,
const int **&  tetrahedron_index 
) const [virtual]

Gets the current mesh geometry.

tetrahedron_index must be used like a matrix. (i.e. tetrahedron_index[cell_index][n], with 0 <= n <= 3)

Deprecated:

Deprecated since Open Inventor 8000
No longer used.
virtual void PbTetrahedronMesh3D::getGeometry ( int &  num_nodes,
const float *&  x_nod,
const float *&  y_nod,
const float *&  z_nod,
int &  num_tetrahedrons,
const int *&  tetrahedron_index 
) const [virtual]

Gets the current mesh geometry.

tetrahedron_index must be used like a vector (i.e. tetrahedron_index[n])

virtual void PbTetrahedronMesh3D::getNodesOwnerCellsInd ( const PbArrayOfInt nod_indices,
PbArrayOfInt owner_cells 
) const [virtual]

Gets the list of index of cells that own the list of node "nod_indices" (for example nod_indices can be the list of indices of a facet, an edge.

..)
