Yes - rectangular screens work. But you probably have something else in

There is currently no support for distortion correction in Equalizer. You
can however set up the typical three-pipe Reality Centre configuration.

The long version:
Right now Equalizer supports a wall description for compounds. A wall
defines a rectangular area in meters, relative to the origin (viewer) by
defining the top-left, bottom-left and bottom-right points of the wall.
Support for projector coordinates (origin, field of view, wall distance) is
Movable screens should be easy to support, it is just a matter of finding an
API so that the application can describe the wall parameters for all views
to the server. The frustum computation is already done per-frame, so it is
just a matter of changing the walls.
Are you really moving your screens? I'm just asking because there is already
a head matrix for tracking.
