```
public void makeNonConforming()
```
    Modify vertex indices of a boundary after elementSet has been made non-conforming.
    Method assumes that boundary has been setup for a conforming element set before, and, additionally, that the element set is already non-conforming. Number of boundary vertices is reduced by one.

    PnConjugate.makeConforming(jv.geom.PgElementSet), PnConjugate.makeNonConforming(jv.geom.PgElementSet)

    Method assumes that boundary has been setup for an element set before.
  - makeElementInd
```
public boolean makeElementInd()
```
    After the vertexInd have been assigned, this method fills the elementInd vector by asking the triangulation for edges. Additionally, the vertices are assigned.
    Method does not work for non-conforming element sets.
    The currently used algorithm performs a linear run over all elements to find the element index of the first edge. For all other boundary vertices, only their neighbourhood is checked. In case of non-manifold vertices, however, another linear run over all elements is performed.
    
    Returns:
    false if missing element set or edge not found, else true.

    Parameters: PgBndPolygon a, pointer on structure of bnd_curve PgBndPolygon b, pointer on structure of bnd_curve Returnvalue: int 0: paste didn't work 1: paste succeeded Description: paste two bnd's of a triang2d structure paste b at the end of a

```
public int bnd_cmp_logic(PgBndPolygon b,
                double maxDist)
```
    Parameters: PgBndPolygon a, pointer on structure of bnd_curve PgBndPolygon b, pointer on structure of bnd_curve Returnvalue: int 0: boundaries are not equal 1: bnd's are equal with m_vertexInd.m_data[0] = b.m_vertexInd.m_data[0] -1: bnd's are inverse equal with m_vertexInd.m_data[0] = b.m_vertexInd.m_data[nop-1] Description: compare boundaries of one triang2d structure, they may have different number of vertices.
  - isShowingIndividualMaterial
```
public boolean isShowingIndividualMaterial()
```
    Get flag if this boundary polygon uses its own material properties instead of inheriting material properties of the base geometry.
    
    Returns:
    true if individual material of this boundary polygon is used
    Since:
    
    JavaView 2.49.005
  - showIndividualMaterial
```
public void showIndividualMaterial(boolean flag)
```
    Set flag if this boundary polygon uses its own material properties instead of inheriting material properties of the base geometry.
    
    Parameters:
    flag - true if individual material of this boundary polygon is used
    Since:
    
    JavaView 2.49.005
  - merge
```
public boolean merge(PgBndPolygon b)
```
    Merge boundary polygon with current object into 'this' and identify last vertex of 'this' with first vertex of argument curve.
    
    Parameters:
    b - PgBndPolygon to be merged into 'this'
    
    Returns:
    true if merge was successfull
  - blend
```
public boolean blend(double s,
            PgGeometry ag,
            double t,
            PgGeometry bg)
```
    Blend between two polygon using this = s*a + t*b.
    
    Specified by:
    
    blend in interface PgGeometryIf
    
    Overrides:
    
    blend in class PgPolygon
    
    Parameters:
    s - weight of vertices of first boundary polygon
    ag - first boundary polygon used for blending
    t - weight of vertices of second boundary polygon
    bg - second boundary polygon used for blending
    
    Returns:
    true on success
  - constrain
```
public boolean constrain()
```
    Project boundary vertices of element set onto curves determined by boundary constraints. Then update vertices of boundary polygon too.
