Class Summary |
| SpatialConstraint |
Spatial Constraint class
The Constraint is really a cone on the sky-sphere. |
| SpatialConvex |
The SpatialConvex class encapsulates all the code for intersection
and lookup. |
| SpatialDomain |
A SpatialDomain manages a list of SpatialConvexes. |
| SpatialEdge |
Spatial Edge class
The Edges are needed at construction time of the spatial index. |
| SpatialGeneral |
Define some constants like Pi, Pi/180, default levels and epsilon |
| SpatialIndex |
The Spatial Index is a quad tree of spherical triangles. |
| SpatialLayer |
SpatialLayer structure - used internally by SpatialIndex. |
| SpatialMarkup |
The Spatial Markup just keeps track of the state of each node in the
Index tree during an intersection with a domain. |
| SpatialQuadNode |
SpatialQuadNode is used as an internal structure in SpatialIndex. |
| SpatialSign |
The sign class is inherited by Constraint and Convex. |
| SpatialVector |
The SpatialVector is a standard 3D vector class with the addition
that each coordinate (x,y,z) is also kept in ra,dec since we expect
the vector to live on the surface of the unit sphere, i.e. |
