Affine variables, which have the virtue of preserving the positive-definite character of matrix-like objects, have been suggested as replacements for the canonical variables of standard quantization schemes, especially in the context of quantum gravity. We develop the kinemat-ics of such variables, discussing suitable coherent states, their associated(More)
Two technologies for reconstruction of environments have emerged in recent years: active scanning with a laser rangefinder, and passive photogrammetry. While these techniques have taken great strides in realism in recent years we believe the best solution for 3D capture ultimately lies in the integration of these two methodologies. To this end we have(More)
