Planetariums and smaller personal domes can provide an immersive environment for
science education, virtual reality, and entertainment. Digital projection
into domes, called "full dome projection" in the industry, can be a technically
challenging and expensive exercise, particularly so for installations with
modest budgets. An alternative full dome digital projection system is presented
based upon a single projector and a spherical mirror to scatter the light onto the
dome surface. The approach offers many advantages over the fisheye lens
alternatives, results in a similar quality result, but at a fraction of the cost.
