Perception Interaction and Light Simulation 3D – PrISE-3D

Production of photorealistic images requires to use light simulation, that highlight visual noise. This noise disappears gradually as a function of the convergence rate of the computing methods, but at a very high time cost. This drawback is particularly penalizing when computing 3D images sequences.
The first aim of the PrISE-3D project is a better understanding of the perceptual mechanisms underlying the perception of image quality through the use of various sterescopic devices with various features.
For this, search procedures of visual convergence of the light simulation algorithms will be considered in the case of relief images. These thresholds will then be used to determine the automatic stopping condition of computation in each part of the images.
The second aim of this project will be to study and develop a mixed renderer (photorealistic rendering in the focus areas of the images and real time rendering in the other areas) by using the results of the perceptual thresholds . This mixed rendered will be develop for immersive environnements and by taking into account both actions and behaviour of the user and its limited field of vision, it should be possible to provide him with high fidelity experiences.
