Detailed Description

Defines a cartesian grid surface mesh.

Class to define a mesh represented by a grid with cartesian coordinates. This mesh is defined by a matrix num_x * num_y points forming (num_x - 1) * (num_y - 1) quadrangles. Each point with index (i, j) in the mesh (except for points along the mesh border) is connected to four points with indices (i+1,j), (i,j+1), (i-1,j), (i,j-1). x, y and z are array of num_x * num_y floats.

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

Member Function Documentation

virtual const PbCell* PbCartesianGrid2D::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 PbQuadrangleCell 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 PbParalCartesianGrid2D.

void PbCartesianGrid2D::getGeometry	(	int &	num_x,
		int &	num_y,
		const float **&	xa,
		const float **&	ya,
		const float **&	za
	)			const

Gets the mesh 3D geometry.

xa-ya-za can be used like a matrix (i.e xa[i][j]) Attention! For a 2D mesh, za is NULL.

void PbCartesianGrid2D::getGeometry	(	int &	num_x,
		int &	num_y,
		const float **&	xa,
		const float **&	ya
	)			const

Gets the mesh 2D geometry.

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

virtual SbVec3f PbCartesianGrid2D::getNodeCoord	(	int	i,
		int	j
	)			const [virtual]

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

Implements PbGrid2D.

Reimplemented in PbParalCartesianGrid2D.

virtual SbVec3f PbCartesianGrid2D::getNodeCoord

(

int

nod_index

)

const [virtual]

Gets the coordinates of a node defined by its index on the grid.

Implements PbGrid2D.

Reimplemented in PbParalCartesianGrid2D.

PbCartesianGrid2D& PbCartesianGrid2D::operator=

(

const PbCartesianGrid2D &

mesh

)

Assignment operator.

Reimplemented from PbGrid2D.

Reimplemented in PbParalCartesianGrid2D.
