Detailed Description

Defines a mesh of hexahedrons.

Class to define an indexed 3D mesh made up of hexahedrons. This mesh is defined by a list of hexahedrons. Each hexahedron is defined by 8 indices of nodes.

The nodes coordinates are defined by 3 arrays x_nod, y_nod, z_nod of num_nodes floats. The hexahedrons are defined by the array hexahedron_index of num_hexahedrons*8 integers. hexahedron_index[(n*8)+p] is the p-th node index of the n-th hexahedron of the mesh (0 <= p <= 7). Each hexahedron must be numbered by repecting the following rule : the 4 first indices define a facet of the hexahedron and orient it towards the interior of the hexahedron.

Each facet of a hexahedron may have 2 references in the mesh, that is, one facet is common to 2 hexahedrons. 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

virtual const PbCell* PbHexahedronMesh3D::getCell

(

int

cell_index

)

const [virtual]

Gets the cell which index is cell_index.

Returns NULL if the cell does not exist, otherwise returns always a PbHexahedronCell 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.

SoDEPRECATED void PbHexahedronMesh3D::getGeometry	(	int &	num_nodes,
		const float *&	x_nod,
		const float *&	y_nod,
		const float *&	z_nod,
		int &	num_hexahedrons,
		const int **&	hexahedron_index
	)			const

Gets the current mesh geometry.

hexahedron_index must be used like a matrix. (i.e. hexahedron_index[cell_index][n], with 0 <= n <= 7)

Deprecated:

Deprecated since Open Inventor 8000
No longer used.

void PbHexahedronMesh3D::getGeometry	(	int &	num_nodes,
		const float *&	x_nod,
		const float *&	y_nod,
		const float *&	z_nod,
		int &	num_hexahedrons,
		const int *&	hexahedron_index
	)			const

Gets the current mesh geometry.

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

virtual void PbHexahedronMesh3D::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.

PbHexahedronMesh3D& PbHexahedronMesh3D::operator=

(

const PbHexahedronMesh3D &

mesh

Assignment operator.

Reimplemented from PbIndexedMesh3D.

void PbHexahedronMesh3D::setGeometry	(	int	num_nodes,
		const float *	x_nod,
		const float *	y_nod,
		const float *	z_nod,
		int	num_hexahedrons,
		const int *	hexahedron_index
	)

Sets a new geometry.
