Detailed Description

Geo interface to a camera.

I wanted to hide the normal vtkCamera API so I did not make this a subclass. The camera is a helper object. You can get a pointer to the camera, but it should be treated like a const.

View up of the camera is restricted so there is no roll relative to the earth. I am going to keep view up of the camera orthogonalized to avoid the singularity that exists when the camera is pointing straight down. In this case, view up is the same as heading.

The state of the view is specified by the vector: (Longitude,Latitude,Distance,Heading,Tilt). Longitude in degrees: (-180->180) Relative to absolute coordinates. Latitude in degrees: (-90->90) Relative to Longitude. Distance in Meters Relative to Longitude and Latitude. above sea level ???? should we make this from center of earth ???? ???? what about equatorial bulge ???? Heading in degrees: (-180->180) Relative to Logitude and Latitude. 0 is north. 90 is east. ???? what is the standard ???? 180 is south. -90 is west. Tilt in degrees: (0->90) Relative to Longitude, Latitude, Distance and Heading.

Transformation: Post concatenate. All rotations use right hand rule and are around (0,0,0) (earth center). (0,0,0,0,0) is this rectilinear point (0, EarthRadius, 0) pointing (0,0,1), view up (0,1,0).

Rotate Tilt around x axis, Rotate Heading around -y axis Center, Translate EarthRadius in y direction. Rotate Latitude around x axis by Latitude, Rotate Longitude around z axis (earth axis),
