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
| 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.

| int & | size_xnod, | |||
| int & | size_ynod, | |||
| int & | size_znod | |||
| ) | const [inline, virtual] |
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)

| int & | num_z, | |||
| const float *& | xa, | |||
| const float *& | ya, | |||
| const float *& | za | |||
| ) | const [inline] |
Gets the mesh geometry.
xa-ya-za must be used like a vector (i.e. xa[n])

| 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])
| SbVec3f PbCartesianGrid3D::getNodeCoord | ( | int | i, | |
| int | j, | |||
| int | k | |||
| ) | const [inline, virtual] |
Gets the coordinates of a node defined by its i,j,k indices on the grid.
Implements PbGrid3D.
Reimplemented in PbParalCartesianGrid3D.
| virtual SbVec3f PbCartesianGrid3D::getNodeCoord | ( | int | nod_index | ) | const [virtual] |
Gets the coordinates of a node defined by its index.

| 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.
