```
Abstract class for all geometry classes in JavaView, and implementation of PgGeometryIf. Users may derive their own geometry classes either from this class resp. its subclasses, or by writing a class implementing the interface PgGeometryIf.

    Panels are not updated if they have not been created yet, or if they are not visible.

```
    Set offset vector in pixel coordinates of label w.r.t. base point. The base point of vertices is the vertex, the base point of elements and edges and polygon edges is the barycenter, i.e. midpoint.
    First two components of attr are pixel coordinates determining the offset with respect to the base point. For example, an offset pair (1,-2) locates label center 1 to the right and 2 pixels up of the base point (since the upper left corner of the display is (0,0) in screen coordinates).
    Third component of attr is PgGeometryIf.LABEL_HEAD or PgGeometryIf.LABEL_CENTER or PgGeometryIf.LABEL_TAIL and indicates whether head, tail, or center of label is located at base+offset.
    Fourth component of attr is PgGeometryIf.LABEL_TOP or PgGeometryIf.LABEL_MIDDLE or PgGeometryIf.LABEL_BASE and indicates whether top, middle, or base of label is located at base+offset. Not implemented yet.
    Fifth component of attr indicates font. For possible fonts see PsConfig.
    Note, it is currently not possible to set the label attribute, say, of a single vertex unless you have a geometry with just one vertex.

    Convert 3D world coordinates into 3D model coordinates of current geometry by multiplication of world coordinates with the inverse model matrix.
    If geometry has no model matrix then no operation is performed.
    
    Parameters:
    geom - geometry whose model matrix is used, if it exists
    baseWorld - 3D world coordinates of view point
    dirWorld - 3D world coordinates of view direction
    baseModel - 3D model coordinates of view point
    dirModel - 3D model coordinates of view direction
  - intersectionWithLine
```
public PvPickEvent intersectionWithLine(PdVector base,
                               PdVector dir)
```
    Method used for picking, should be overridden by subclasses.
    
    Specified by:
    
    intersectionWithLine in interface PgGeometryIf
  - blend
```
public boolean blend(double s,
            PgGeometry a,
            double t,
            PgGeometry b)
```
    Blend between two geometries, used in interpolation and computing the associate surfaces this = s*a + t*b.
    
    Specified by:
    
    blend in interface PgGeometryIf
    
    Parameters:
    s - weight of vertices of first elementSet
    t - weight of vertices of second elementSet
    a - first source geometry used for blending
    b - second source geometry used for blending
    
    Returns:
    true on success
  - merge
```
public boolean merge(PgGeometryIf geomIf)
```
    Add another of same geometry of same type to this geometry. If types of geometries are different then nothing is done.
    Method applies model and ambient matrices to argument geometry if such local transformation matrices exist.
    
    Specified by:
    
    merge in interface PgGeometryIf
    
    Parameters:
    geomIf - geometry merged into the current geometry
    
    Returns:
    true on success
  - getCenterOfElement
```
public static PdVector getCenterOfElement(PdVector center,
                          PdVector[] vertex,
                          int[] vertInd)
```
    Compute the barycenter of a geometry element like face or polygon edge.
    
    Parameters:
    center - existing vector of dimension m_dim which will be filled and returned
    vertex - vertex array to which the index vector refers
    vertInd - index vector with indices in the vertex array
    
    Returns:
    Argument center is filled with the position of the barycenter
  - reflect
```
public PgGeometry reflect(PdMatrix mat,
                 boolean bOrient,
                 boolean bVector)
```
    Generate a cloned geometry and transform vertices by a matrix. For example, this method is called to calculate mirror images of a geometry. Orientation of geometry affects surface vectors.
    
    Specified by:
    
    reflect in interface PgGeometryIf
    
    Parameters:
    mat - 3*3 or 4*4 transformation matrix
    bOrient - flag whether to keep the orientation of the geometry
    bVector - flag whether to keep the orientation of vectors
    
    Returns:
    new reflected copy of the geometry
  - getTextureImageName

public java.lang.String getTextureImageName()
```
    Get name of texture image, a full URL or a relative file name.
    
    Specified by:
    
    getTextureImageName in interface PgGeometryIf
  - setTextureImageName
```
public void setTextureImageName(java.lang.String name)
```
    Set name of texture image, a URL or a relative file name.
    
    Specified by:
    
    setTextureImageName in interface PgGeometryIf
  - getTextureImage
```
public java.awt.Image getTextureImage()
```
    Get image of texture.
    
    Specified by:
