increasing. This paper presents an augmented reality system that renders the virtual elements from models
based on the light fields. The use of these models allow us to obtain higher level of photorealism than representations
that render polygons. Using light fields also allows us to keep constant the rendering time. The
presented system has been implemented using the Open Source library ARToolKit and a spherical model of
the light field based on the direction-and-point parameterization (DPP) with some associated depth information.
The system has been validated using different light fields, and it has been compared its performance with
a classic version of the ARToolKit library based on VRML files. The presented augmented reality system can
be applied to the visual inspection of synthetic objects of great complexity or based on real images.
