The Eighth International Immersive Projection Technology Workshop, May 13-14, 2004, Ames, Iowa, USA
We present a multi-projector stereoscopic display which incorporates a high-resolution inset image, or fovea. The system uses four projectors, and the image warping required for on-screen image alignment and foveation is applied as part of the rendering pass. We discuss the problem of ambiguous depth perception between the boundaries of the inset in each eye and the underlying scene, and present a solution where the inset boundaries are dynamically adapted as a function of the scene geometry. An efficient real-time method for boundary adaptation is introduced. It is applied as a post-rendering step, does not require direct geometric computations on the scene, and is therefore practically independent of the size and complexity of the model.
