In the early stage of creation, the architect tests his work hypotheses by making many adjustments while designing. During the sketching phase, the existing modeling tools are not compatible with the iterative nature of this process. So the challenge lies in the definition of a model which will allow the whole creative process with its various trying and going back during the phase of conception....
This paper presents a method to reconstruct the surface reflectance of objects from images. For objects with spatially-varying materials, we assume that each point can be represented as a weighted sum of several basic materials. First, a cluster algorithm is applied to automatically compute the number of basic materials. Then, the weight map and parameters of the reflectance model are iteratively...
We report on the design and experimental validation of a distributed Brillouin-based optical fiber sensor embedded into concrete structures for temperature and strain measurement. A composite-made wave-like coating designed by finite-element analysis ensures the sensor is transferring optimally temperature and strain fields from the concrete to the optical fiber, where Brillouin scattering takes place...
