A team of developers at Catopsis plan to introduce a novel new indoor projector system which can transform your walls into one large panoramic viewing screen. When the Immersis LED projector is first positioned in the room it loads a file containing a 3D representation of the room including the floor and ceiling features and then calculates the amount of correction it needs to apply to the projected image so that, from the point of view of the projector, the image looks as though it is being shown on one large screen occupying a hemisphere.

The image can be augmented by a television or monitor so that from one position in the room the edges of the image on the monitor lines up with the image projected on the walls.

According to their Kickstarter page the system uses 3D anamorphic technology: the first step is to create a 3D model of the projection space using a configuration tool that allows you to describe the dimensions of the space. Depending on the room dimensions, the projector position and the use of an optional television, the system makes a calibration file that is used as a basis for the anamorphosis (deformation) of the image. The anamorphosis is processed in real time by the computer and graphics card in the Immersis.

With a system like this there can only be one sweet spot from which the viewed image will be true, the distortion will become more evident the further you move away from this point. Recesses in the wall surface can be compensated for but features projecting into the room (such as a chimney breast) will produce dark shadows in the image when viewed off the centre line. The team have set a goal of $100,000 to fund the project and with 22 days to go they have already hit their target.
