PhD Thesis

Dimensional Analysis of Light Transport

This PhD aims at exploring light transport through the transversal view of light transport operators between the infinite dimensional function spaces of light fields (imagine, e.g., reflectance as an operator that transforms a distribution of incident light into a distribution of reflected light). In addition to be linear in these spaces, these operators are also very sparse. As a side effect, the sub-spaces of light distributions that are actually relevant during the computation of a solution always boil down to a low dimensional manifold embedded in the full space of light distributions. Reflectance over ''smooth'' materials for instance, converts incident illumination into a low dimensional set of reflected light distributions. Rather than using linearity to compress precomputed radiance transfer (PRT), we want to leverage recent ad-hoc dimensionality reduction methods: Compressive sensing, Gaussian processes, Monte-Carlo eigenanalysis and unsupervised machine learning from huge volume of generated data. Expected results are two-fold: (1) a theoretical understanding of the dimensionality and structure of light transport operators (examples include scattering, reflectance, global transport in glossy scenes). Possible applications will cover re-lighting, material acquisition and efficient simulation of complex light transport problems. (2) We also envision that controlled approximations of the low dimensional operators will open the way to efficient approximations of light transport which may also be suitable for real time applications such as interactive lighting for video games. The PhD candidate should have a solid background in mathematics and programmation. Knowledge in GPU programming is a plus. ...   »More information

Exploring Difficult Manifolds for Light Transport

To produce photorealistic pictures, we seek all paths connecting light source and camera, after multiple bounces on the scene geometry.
Explicitly finding all paths is difficult, especially with multiple refractive interfaces. Manifold Exploration is the idea that the set of good paths forms a manifold in path space, and once we have a point on this manifold, we can explore path space while staying on it.
Manifold exploration is great for exploring difficult paths, but we have to find a point on the manifold first. With two specular interfaces (especially refractive), this becomes difficult. Our goal in this project is to extend manifold exploration to these difficult cases. ...   »More information

Adapting the Combined Diffraction-MicroFacet Model for designers

The realism of photorealistic pictures depends a lot on the realism of the materials used to depict the scene. The micro-facet model is widely used in research and industry for its simplicity and versatility. It covers materials from diffuse to specular, and connects to physical parameters (material chemical composition, roughness). In Summer 2017, we introduced a new model that extends the micro-facet model by taking into account diffraction effects in the microgeometry of the surface. The new model is better at representing the observed behaviour of actual materials. While the new model is good at representing actual materials, it was not designed for artists and designers. The goal in this research project is to adapt it for practical users: professional artists and designers: simplification, intuitive parameters, filtering......   »More information

Ageing and Reverse-Ageing for Cultural Artifacts

The realism of photorealistic pictures depends a lot on the materials used to depict the scene. When we depict actual objects, it is good to have a connection with the physical properties: chemical composition, surface roughness, etc. It is especially interesting when we deal with cultural artifacts, such as paintings, sculptures, metallic artifacts. What we have is how they look now, and their current chemical composition. What we would like to have is how they looked when they were new (reverse-ageing). Some ageing effects are related to oxidation; the effects can be just a change in the chemical properties of the material, like tin transforming into tin oxide. In more extreme cases, there is also a change in the surface geometry, like iron transforming into rust. Our goal in this project is to take models of ancient cultural artefacts, such as tin vases or bronze swords, and reverse the effects of time to produce photorealistic pictures of the artefacts as they were when they were new. ...   »More information
