Detailed Description

Defines a volume mesh of polyhedrons.

Class to define an indexed 3D mesh. Each cell of this type of mesh is a polyhedron with 4, 5, 6 or 8 nodes. Each polyhedron is defined by a list of node indices.

The nodes coordinates are defined by 3 arrays x_nod, y_nod, z_nod of num_nodes floats. The cells are defined by the array cell_type (size num_cells) and cell_index. cell_type[n] defines the number of nodes in the n-th cells: if cell_type[i] = 4, the i-th cell is a tetrahedron, if cell_type[i] = 5 it is a pyramid, if cell_type[i] = 6 it is a prism, and if cell_type[i] = 8 it is an hexahedron. cell_index is an array of S integers, where S = cell_type[0] + cell_type[1] + ... + cell_type[num_nodes - 1]. cell_index contains the num_cells lists of node indices which define each cell topology.

Each facet of a cell may have 2 references in the mesh, that is, one facet is common to 2 cells. 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 * PbIndexedMesh3D::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 (ie flat tetrahedron). Attention! this method returns always the same adress of an internal private cell. This private cell is updated each time getCell is called.

Implements PbMesh.

Reimplemented in PbHexahedronMesh3D, and PbTetrahedronMesh3D.

◆ getCoordinates()

void PbIndexedMesh3D::getCoordinates	(	const float *&	xnod,
		const float *&	ynod,
		const float *&	znod,
		int &	size_xnod,
		int &	size_ynod,
		int &	size_znod
	)		const

inlinevirtual

Get the current coordinates of the nodes of this mesh.

Parameters

xnod	array of x coord
ynod	array of y coord
znod	array of z coord
size_xnod	size of the array xnod
size_ynod	size of the array ynod
size_znod	size of the array znod

Reimplemented from PbMesh.

◆ getGeometry()

void PbIndexedMesh3D::getGeometry	(	int &	num_nodes,
		const float *&	x_nod,
		const float *&	y_nod,
		const float *&	z_nod,
		int &	num_cells,
		const int *&	cell_index,
		const int *&	cell_type
	)		const

Gets the current mesh geometry.

◆ getNodeCoord()

virtual SbVec3f PbIndexedMesh3D::getNodeCoord ( int nod_index ) const

inlinevirtual

Gets the coordinates of a node.

Implements PbMesh.

Definition at line 158 of file PbIndexedMesh3D.h.

◆ getNodeOwnerCellsInd()

virtual void PbIndexedMesh3D::getNodeOwnerCellsInd	(	int	nod_index,
		PbArrayOfInt &	owner_cells
	)		const

virtual

Gets the list of index of cells that own the node "nod_index".

Implements PbMesh.

◆ getNodes()

void PbIndexedMesh3D::getNodes	(	int &	num_nodes,
		const float *&	x_nod,
		const float *&	y_nod,
		const float *&	z_nod
	)		const

Gets the mesh nodes coordinate arrays.

◆ operator=()

PbIndexedMesh3D & PbIndexedMesh3D::operator= ( const PbIndexedMesh3D & mesh )

Assignment operator.

◆ setCoordinates()

void PbIndexedMesh3D::setCoordinates	(	const float *	x_nod,
		const float *	y_nod,
		const float *	z_nod
	)

virtual

Set new node coordinates without modifying the mesh topology.

For performance reasons, this method should be called instead of setGeometry when doing a mesh deformation animation. It allows to update the coordinates of a existing level surface, skin, cross section etc, without rebuilding them totally.

Reimplemented from PbMesh.

◆ setGeometry()

void PbIndexedMesh3D::setGeometry	(	int	num_nodes,
		const float *	x_nod,
		const float *	y_nod,
		const float *	z_nod,
		int	num_cells,
		const int *	cell_index,
		const int *	cell_type
	)

Sets a new geometry.
