The invention concerns a device for generating mutual photometric effects. The invention concerns also a server for delivering photometric parameters for generating mutual photometric effects and a system including such a device and such a server. According to the invention the device (1) 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 for these photometric parameters, - 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.
