Detailed Description

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.

Member Function Documentation

◆ getCell()

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.

◆ getGeometry() [1/2]

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])

◆ getGeometry() [2/2]

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

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...)
