com.openinventor.inventor.Inventor

com.openinventor.imageviz.SbStructuredQuadrilateralMesh

All Implemented Interfaces:

SafeDisposable

public class SbStructuredQuadrilateralMesh
extends Inventor
implements SafeDisposable

Structured quadrilateral mesh. Its nodes are ordered and can be accessed by i, j indices. All cells are quadrilateral.

Defines a list of 3d vertices that can be accessed by (i,j) indices.

Constructor Detail

SbStructuredQuadrilateralMesh

public SbStructuredQuadrilateralMesh(long numCellsI,
                                     long numCellsJ)

Constructor requiring the mesh number of cells in row and column.

Method Detail

isDisposable

public boolean isDisposable()

Description copied from interface: SafeDisposable

Returns a boolean flag which indicates if it is safe to call SafeDisposable.dispose() on the object.

Specified by:

isDisposable in interface SafeDisposable

Returns:

true if the object can be disposed in a safe manner

dispose

public boolean dispose()

Description copied from class: Inventor

Explicitly call this method to force object to dispose its unmanaged resources. The object may not be reused in the application code after this call.

Specified by:

dispose in interface SafeDisposable

Overrides:

dispose in class Inventor

Returns:

true if this object native resources were successfully disposed; false if it was already disposed or no native resources has been registered for this object.

getNumCellsJ

public long getNumCellsJ()

Returns the mesh number of cell by column.

setVertex

public void setVertex(long i,
                      long j,
                      SbVec3f vertex)

Sets the position of a vertex. Throws an error if the indices are out of the mesh range.

Parameters:

i - column index of the vertex to modify. i must be in range [0-getNumCellsI()].

j - row index of the vertex to modify. j must be in range [0-getNumCellsJ()].

vertex - new value.

getVertex

public SbVec3f getVertex(long i,
                         long j)

Returns the vertex position. Returns an empty vertex if the indices are out of the mesh range.

Parameters:

i - column index of the vertex to modify. i must be in range [0-getNumCellsI()].

j - row index of the vertex to modify. j must be in range [0-getNumCellsJ()].

getNumCellsI

public long getNumCellsI()

Returns the mesh number of cell by row.
