Presented here is a low cost immersive projection
system requiring a single data projector and a low cost
spherical mirror. The final projection surface can be any
reasonable shape, for example, a partial cylinder
enveloping the gamer, a hemispherical dome, or a
rectangular room. For this and indeed for any immersive
projected environment, game developers need to start
thinking beyond single perspective projections. On option
discussed here is to implement the cubic map multipass
rendering pipeline
