Detailed Description

Defines a cartesian grid volume mesh.

Class to define a mesh represented by a 3D grid with cartesian coordinates. This mesh is defined by a matrix num_x * num_y * num_z points forming (num_x - 1) * (num_y - 1) * (num_z - 1) hexahedrons. Each point with index (i, j,k) in the mesh (except for points along the mesh border) is connected to six points with indices (i+1,j,k), (i,j+1,k), (i-1,j,k), (i,j-1,k), (i,j,k+1), (i,j,k-1). The values on the mesh nodes are defined by the addValuesSet() method, where val argument is an array of num_x * num_y * num_z floats.

Member Function Documentation

◆ getCell()

virtual const PbCell * PbCartesianGrid3D::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.

Implements PbMesh.

Reimplemented in PbParalCartesianGrid3D.

◆ getCoordinates()

void PbCartesianGrid3D::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.

Idem as getXYZGeometry.

Parameters

xnod	: array of x coordinate of the mesh nodes.
ynod	: array of y coordinate of the mesh nodes.
znod	: array of z coordinate of the mesh nodes.
size_xnod	: size of the array xnod ( = num nodes of this mesh)
size_ynod	: size of the array ynod ( = num nodes of this mesh)
size_znod	: size of the array znod ( = num nodes of this mesh)

Reimplemented from PbMesh.

Reimplemented in PbParalCartesianGrid3D.

◆ getGeometry() [1/2]

void PbGrid3D::getGeometry	(	int &	num_x,
		int &	num_y,
		int &	num_z,
		const float *&	x,
		const float *&	y,
		const float *&	z
	)		const

Gets the mesh geometry.

x-y-z must be used like a vector (i.e. x[n]).

◆ getGeometry() [2/2]

void PbCartesianGrid3D::getGeometry	(	int &	num_x,
		int &	num_y,
		int &	num_z,
		const float ***&	xa,
		const float ***&	ya,
		const float ***&	za
	)		const

Gets the mesh geometry.

xa-ya-za can be used like a matrix (i.e. xa[i][j][k])

◆ getNodeCoord() [1/2]

SbVec3f PbCartesianGrid3D::getNodeCoord	(	int	i,
		int	j,
		int	k
	)		const

inlinevirtual

Gets the coordinates of a node defined by its i,j,k indices on the grid.

Implements PbGrid3D.

Reimplemented in PbParalCartesianGrid3D.

Definition at line 138 of file PbCartesianGrid3D.h.

◆ getNodeCoord() [2/2]

virtual SbVec3f PbCartesianGrid3D::getNodeCoord ( int nod_index ) const

virtual

Gets the coordinates of a node defined by its index.

Implements PbGrid3D.

Reimplemented in PbParalCartesianGrid3D.

◆ operator=()

PbCartesianGrid3D & PbCartesianGrid3D::operator= ( const PbCartesianGrid3D & mesh )

Assignment operator.

◆ setCoordinates()

void PbCartesianGrid3D::setCoordinates	(	const float *	xnod,
		const float *	ynod,
		const float *	znod
	)

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.

Reimplemented in PbParalCartesianGrid3D.
