public class PgPointSet
extends PgGeometry
```
Base class for most geometric objects with points resp. vertices, for example point sets, polygons, element set, and other simplicial complexes.
The class has an array of n-dimensional points where each point is an instance of type PdVector containing the n coordinate components. Additionally, there exist instance variables for vertex normals, vertex colors, vertex texture coordinates, and other vertex properties. Note, that such vertex properties are not stored with each vertex but each property is stored in an additional array of same length as the array of vertices. If a property is not available then the corresponding array is null.
The dimension of all points is determined as argument of the constructor and cannot be changed later. The dimension is the same for all points of the point set. There exist several utility functions to allocate and modify the number of points, for example,
```
        setNumVertices(int)
 
```
allocates num vertices. Internally, there exists a cache to reduce the number of actual memory allocations. The size of the cache is managed by protected methods.
Whenever the number of vertices is changed, the class automatically adjusts the size of those vertex properties which are currently in use, i.e. whose array is not null.
Applications may modify the coordinates of vertices and of vertex properties by direct method calls such as
```
        setVertex(int, PdVector)
 
```
which sets the vertex with index ind equal to the vertex v by copying the coordinates. Alternatively, if an application modifies a larger number of vertices then the application may prefer to obtain the coordinate array from the point set and directly modify the array
```
        PdVector [] vertex = pointSet.getVertices();
        for (int i=0; i<pointSet.getNumVertices(); i++)
                vertex[i].copy(v);
 
```
The same choice is available for arrays containing vertex properties. Note, that subclasses, such as PgElementSet, may not reference all vertices, e.g. if the currently active elements consists of a subset of all vertices. Also note, that the actual size of the vertex array may differ from m_numVertices for efficiency reasons. Therefore, do not use vertex.length but use getNumVertices().
A good start to obtain further insight are methods like computeTorus (if source code access to JavaView is available), or the tutorial applets of JavaView.

                2. either geometry has local colors.
