Abstract :
Light fields are an image-based representation that represents objects using sets of digital images. Light fields are usually comprised of 4D radiance data that can be used for 3D rendering or 4D display on autostereoscopic and certain types of volumetric displays. We present a modeling and rendering system for spherical isotropic light fields. These are made of images captured with cameras placed on a sphere´s surface looking inwards. The system implements a multiresolution representation for both the spatial and the directional domains of the light field. This representation supports continuous levels of detail and adaptive frame rate control.
