| Title: |
Projection System |
| Abstract: |
A projection system having a set of projectors that cast images: (i) onto
the concave surface of a hemispherical dome, as is usual in planetariums
and (ii) onto the surface of a centrally located sphere. The images thus
cast may be coordinated by a controlling computer program, so that
changes in the content or orientation of the images on the sphere result
in corresponding changes in the images on the dome and vice versa.
