The device comprises a receiver for receiving and demultiplexing the visual data sets and photometric parameters respectively associated with the data sets, a module for defining the mutual photometric effects to be generated for these photometric parameters, a compositor and a rendering module for positioning the visual data sets in the common support space and applying the effects defined for the photometric parameters from at least one of the visual data sets to at least one other of the visual data sets so that at least one visual data set influences one other visual data set in the common support space.
1. Device to generate mutual photometric effects between a plurality of visual data sets, comprising means to position the visual data sets in a common support space characterized in that it comprises:
means for receiving and demultiplexing said visual data sets and photometric parameters respectively associated with said data sets,
means for defining said mutual photometric effects to be generated from these photometric parameters on the basis of at least one rendering modi, said rendering modi defining by which visual data sets a given visual data set is influenced and how said given visual data set is influenced,
composition and rendering means for positioning said visual data sets in said common support space and applying said effects defined for said photometric parameters from at least one of said visual data sets to at least one other of said visual data sets so that at least one visual data set influences one other visual data set in said common support space.
2. Device according to claim 1 wherein the means for defining the effects of said photometric parameters manage at least one of their storage, their numerical precision, their spatial resolution and their rendering together with visual data sets.
3. Device according claim 1 wherein the photometric parameters are illumination and reflection properties, the illumination properties being selected from among the spatial intensity distribution of light, the position of light sources, the shape and the color of light sources and the reflection properties being selected from among the surface color, the specular color, the reflection geometry and the polarization.
