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.

PbCartesianGrid3D::~PbCartesianGrid3D | ( | ) |
Destructor.
|
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.

Idem as getXYZGeometry.
xnod | : array of x coordinate of the mesh nodes. |

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.
