| This thesis presents a new multi-projector front-projection display system that can be used for an immersive environment. The implementation of such a system faces new challenges that were avoided by design in CAVE-like systems. These include removing the perspective warping from misaligned projectors and adjusting the intensity to create a uniformly lit display in regions where projectors overlap. Also, when the display is in use, occluding objects between the projector and the display surface cause shadows on the display that must be removed. These three issues have been addressed in this work based in part on algorithms from the field of computational geometry and on techniques from existing projector systems. |
