Common properties and methods shared by all geometric objects. Geometries are objects that define a spatial location and and associated geometric shape.
com.github.davidmoten.rtree.geometry.Geometry
A geometrical region that represents an Entry spatially. It is recommended that implementations of this interface implement equals() and hashCode() appropriately that entry equality checks work as expected.

Geometry defines a leaf node of the scene graph. The leaf node contains the geometric data for rendering objects. It manages all rendering information such as a {@link Material} object to define how the surfaceshould be shaded and the {@link Mesh} data to contain the actual geometry. @author Kirill Vainer

The base class for all geometric objects.

Binary Predicates
Because it is not clear at this time what semantics for spatial analysis methods involving GeometryCollections would be useful, GeometryCollections are not supported as arguments to binary predicates (other than convexHull) or the relate method.
Set-Theoretic Methods
The spatial analysis methods will return the most specific class possible to represent the result. If the result is homogeneous, a Point, LineString, or Polygon will be returned if the result contains a single element; otherwise, a MultiPoint, MultiLineString, or MultiPolygon will be returned. If the result is heterogeneous a GeometryCollection will be returned.
Because it is not clear at this time what semantics for set-theoretic methods involving GeometryCollections would be useful, GeometryCollections are not supported as arguments to the set-theoretic methods.
Representation of Computed Geometries
The SFS states that the result of a set-theoretic method is the "point-set" result of the usual set-theoretic definition of the operation (SFS 3.2.21.1). However, there are sometimes many ways of representing a point set as a Geometry.
The SFS does not specify an unambiguous representation of a given point set returned from a spatial analysis method. One goal of JTS is to make this specification precise and unambiguous. JTS will use a canonical form for Geometrys returned from spatial analysis methods. The canonical form is a Geometry which is simple and noded:
- Simple means that the Geometry returned will be simple according to the JTS definition of isSimple.
- Noded applies only to overlays involving LineStrings. It means that all intersection points on LineStrings will be present as endpoints of LineStrings in the result.
This definition implies that non-simple geometries which are arguments to spatial analysis methods must be subjected to a line-dissolve process to ensure that the results are simple.
Constructed Points And The Precision Model
The results computed by the set-theoretic methods may contain constructed points which are not present in the input Geometry s. These new points arise from intersections between line segments in the edges of the input Geometrys. In the general case it is not possible to represent constructed points exactly. This is due to the fact that the coordinates of an intersection point may contain twice as many bits of precision as the coordinates of the input line segments. In order to represent these constructed points explicitly, JTS must truncate them to fit the PrecisionModel.
Unfortunately, truncating coordinates moves them slightly. Line segments which would not be coincident in the exact result may become coincident in the truncated representation. This in turn leads to "topology collapses" -- situations where a computed element has a lower dimension than it would in the exact result.
When JTS detects topology collapses during the computation of spatial analysis methods, it will throw an exception. If possible the exception will report the location of the collapse.
#equals(Object) and #hashCode are not overridden, so that when two topologically equal Geometries are added to HashMaps and HashSets, they remain distinct. This behaviour is desired in many cases. @version 1.7

Geometry is an abstract class that specifies the geometry component information required by a Shape3D node. Geometry objects describe both the geometry and topology of the Shape3D nodes that reference them. Geometry objects consist of four generic geometric types:
- Compressed Geometry
- GeometryArray
- Raster
- Text3D
Each of these geometric types defines a visible object or set of objects. A Geometry object is used as a component object of a Shape3D leaf node.
