Detailed Description

MeshViz Defines a quadrangle cell of a surface mesh.

A quadrangle cell is not necessarily a square, it can be a rectangle or a lozenge.

Nodes and edges are numbered as following :

                3-----------2   edge 0 = 01
                |           |   edge 1 = 12
                |           |   edge 2 = 23
                |           |   edge 3 = 30
                |           |
                |           |
                0-----------1

Member Function Documentation

virtual float PbQuadrangleCell::getArea (  )  const [virtual]

Gets the area of a cell.

Implements PbCell.

void PbQuadrangleCell::getDerivs ( const SbVec3f pcoord,
float *  derivs 
) const

Gets the derivs of a point defined by its parametric coordinates.

virtual float PbQuadrangleCell::getLongestEdgeLength (  )  const [virtual]

Gets the length of the longest edge of the cell.

Implements PbCell.

virtual void PbQuadrangleCell::getNodesIndexOfEdge ( int  edge,
PbArrayOfInt nodes_index 
) const [virtual]

Gets the array of 2 index mesh's nodes that belongs to a given edge of this cell.

(edge must be >=0 and < 4)

Implements PbCell.

virtual void PbQuadrangleCell::getNodesIndexOfFacet ( int  facet,
PbArrayOfInt nodes_index 
) const [virtual]

Gets the array of index mesh's nodes that belongs to a given facet of this cell.

(facet must be == 0).

Implements PbCell.

virtual void PbQuadrangleCell::getNodesLocalIndexOfEdge ( int  edge,
PbArrayOfInt nodes_index 
) const [virtual]

Gets the array of 2 nodes index that belongs to a given edge of this cell.

edge must be >=0 and < 4. Each index is >=0 and < 4

Implements PbCell.

virtual void PbQuadrangleCell::getNodesLocalIndexOfFacet ( int  facet,
PbArrayOfInt nodes_index 
) const [virtual]

Gets the array of node index that belongs to a given facet of this cell.

facet must be == 0. Each index is >=0 and < 4.

Implements PbCell.

virtual float PbQuadrangleCell::getVolume (  )  const [inline, virtual]

Returns always 0.

Implements PbCell.

virtual void PbQuadrangleCell::getWeight ( const SbVec3f pcoord,
float *  weight 
) const [virtual]

Gets the 4 weights of a point defined by its parametric coordinates.

Implements PbCell.

virtual int PbQuadrangleCell::locatePoint ( const SbVec3f coord,
float  tolerance,
SbVec3f pcoord 
) const [virtual]

Returns 1 if the point is inside the cell, 0 otherwise.

Gets also the parametric coordinate of the point and its weights

Implements PbCell.

PbQuadrangleCell& PbQuadrangleCell::operator= ( const PbQuadrangleCell cell  ) 

Assignment operator.

Reimplemented from PbCell.
