Abstract
A method for rendering a view from a lightfield includes identifying a ray associated with a portion of the view and selecting a set of camera views from a plurality of camera views representing the lightfield based on an intersection point of the ray with a plane. Each camera view has an associated contribution region disposed on the plane. The associated contribution region overlaps contribution regions associated with other camera views of the set of camera views at the intersection point. The method also includes determining a characteristic of the ray based on a contribution factor for each camera view of the set of camera views. The contribution factor is determined based on the relative position of the intersection point within the associated contribution region.
