Direct Known Subclasses:

PbCartesianGrid3D, PbRegularCartesianGrid3D

public class PbGrid3D
extends PbMesh3D

Defines an abstract grid volume mesh. This class defines a mesh of which topology is a regular grid made of num_x * num_y * num_z nodes. Each node 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 PbMesh.addValuesSet() method, where argument val is an array of num_x * num_y * num_z floats.

Method Detail

getNodeCoord

public SbVec3f getNodeCoord(int i,
                            int j,
                            int k)

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

getNodeIndices

public int[] getNodeIndices(int nod_index)

Calculates indices i,j,k that verify (i*num_y + j)*num_z + k.

getDim

public int[] getDim()

Gets the dimensions num_x, num_y, num_z of the grid.

getCellIndices

public int[] getCellIndices(int cell_index)

Calculates indices i,j,k that verify cell_index = (i*(num_y-1) + j)*(num_z-1) + k.

setGeometry

public void setGeometry(int num_x,
                        int num_y,
                        int num_z,
                        float[] x,
                        float[] y,
                        float[] z)

Defines a volume mesh geometry. The size of the x array depends on the derived class that calls this method. It is either num_x or num_x * num_y * num_z. Idem for y and z array.
