The usage of projected displays in everyday office environments is still uncommon due to deficiencies in nowadays projection systems. An automatic calibration routine for multi-projector setups should adopt to the existing room geometry while not restricting the users' workflow to specific applications or by modifying their desktop environment.

We present a geometry-adaptive calibration and rendering application for multi-planar surfaces which applies warping and alpha blending to an unmodified X desktop, implemented as plugin for an existing 3D hardware-accelerated compositing window manager. The transformations are performed transparently to X applications and require negligible computational resources.
