Claim:
1. An imaging method for generating output information that depicts a scene from a virtual viewpoint, the method comprising the acts: receiving first data, the received first data representing image data captured of the scene by a first camera system from a first viewpoint; receiving second data, the received second data representing image data captured of the scene by a second camera system from a second viewpoint; based at least in part on the received first data, generating first projected disk data corresponding to positions and energies of plural projected first disks, the first projected disk data taking into account a point spread function for the first camera system, each of the plural projected first disks having a different spatial orientation, but all of said plural projected first disks facing the first viewpoint; based at least in part on the received second data, generating second projected disk data corresponding to positions and energies of plural projected second disks, the second projected disk data taking into account a point spread function for the second camera system, each of the plural projected second disks having a different spatial orientation, but all of said plural projected second disks facing the second viewpoint; defining an array of image cells comprising the output information, each image cell having a boundary and defining an area, each of the image cells corresponding to a region of the scene; and for each of said cells, defining a value thereof by integrating across its area: (a) contributions from one or more first projected disks that fall within its boundary, and (b) contributions from one or more second projected disks that fall within its boundary; wherein the contribution from at least one of said projected disks that falls within the boundary of a cell is reduced in accordance with a reflectivity function, that is dependent on a spatial orientation of the projected disk relative to said virtual viewpoint.
