摘要： A method and system acquire and display light fields. A continuous light field is reconstructed from input samples of an input light field of a 3D scene acquired by cameras according to an acquisition parameterization. The continuous light is reparameterized according to a display parameterization and then prefiltering and sampled to produce output samples having the display parametrization. The output samples are displayed as an output light field using a 3D display device.

摘要： A method and system for progressively rendering radiance for a volumetric medium is provided. A photon simulation produces a representation of photon beams in a scene. The photon beams are rendered with respect to a camera viewpoint, by computing an estimated radiance associated with the photon beams. A global radius scaling factor is applied to the photon beams. Over multiple iterations of these steps, the global radius scaling factor is progressively decreased, thereby reducing overall error by facilitating convergence. This order can be mixed up. Finally, the renderer can be efficiently implemented on the GPU as a splatting operation, for use in interactive and real-time applications.
