POST-DOC

Rendering of stylized mountain panorama maps

In this project, our goal is to design a process to produce panoramas starting from cartographic and topographic data as can be provided by IGN or OpenStreetMap. For that, we collaborate with Arthur Novat in order to understand and formalize the various steps of the drawing of a panorama. Arthur is the son of Pierre Novat who founded The Atelier Novat in the 60’s that became the French standard for mountain panoramas. ...   »More information

Efficient and realistic rendering of image-based models

Our goal is to improve the realism of Image Synthesis, by including real-world, complex objects. Through a cooperative project, we have access to high-quality image-based models. In this post-doc, we will focus on rendering them, inside classical geometrical scenes.

Our work will focus on efficient and realistic rendering of image-based models, including lighting, shadowing and re-lighting effects. We will focus our research in three major directions:

  1. efficient rendering of image-based models, with a rendering cost proportional to the visual complexity of the model, not to the image resolution;
  2. self-shadowing and masking effects: just like parts of the models are hiding each other in the acquisition process, they are also hiding each other in the rendering process. This has an influence both on the picture of the model (masking effects) and on the illumination of the model (self-shadowing effects);
  3. re-lighting of the models: the image-based model was acquired under specific lighting conditions. For a realistic rendering under different lighting conditions, we need to model the influence of lighting on the image-based model, including both direct and indirect lighting.

Postdoc: MIRO: Methods for the legible and Interactive Rendering Of 3D complex data

In this project, we are interested in using NPR for the interactive and legible rendering of complex 3D scenes. Many examples in scientific visualization prove that photorealism does not always offer meaningful images. For example in medical books, the representation of organs is more frequently based on sketches and annotations than on photographs. The postdoc will on these topics, in the context of archeology, museography, medical simulation, all applications that require specialized visualizations. This postdoc will take place 12 months in Grenoble (ARTIS team) and 6 months en Bordeaux (IPARLA team) and is funded by INRIA. ...   »More information

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

Acquisition de propriétés de matériaux dans un contexte de réalité augmentée

Le processus classique en synthèse d’images consiste à créer un modèle géométrique des objets, puis à y a jouter des propriétés de matériaux, et enfin à calculer la simulation de l’éclairage sur ce modèle. Ce processus limite le réalisme, notamment en ce qui concerne les modèles issus du monde réel.

Notre objectif est de permettre l’acquisition des propriétés de réflectance d’objets issus du monde réel, afin de permettre leur placement dans des mondes virtuels. Les applications concernent aussi bien les effets spéciaux dans le cinéma que le réalisme dans les jeux vidéos.

Cette thèse, financée par la région Rhône-Alpes, est réalisée en collaboration avec le laboratoire LIRIS, et le doctorant sera à 50 % de son temps au LIRIS.

Rendu Temps-Réel de Modèle Complexes

Nous nous plaçon dans un projet coopératif, où nous avons accès à des modèles complexes, dont la géométrie est acquise par exemple par scanners 3D.

Ces modèles sont trop complexes pour pouvoir être utilisés dans des applications de rendu temps-réel. Il est donc nécessaire de les simplifier et d'inventer de nouvelles représentations, dites représentations alternatives, qui permettront une représentation en temps-réel tout en conservant les détails géométriques fins que donne l'acquisition.

Dans une deuxième étape de travail, nous voulons simuler l'éclairage sur ces représentations alternatives, en commençant par l'éclairage direct et les ombres, puis l'éclairage indirect.

Notre objectif est de pouvoir inclure ces objets dans des scène en Image de Synthèse, en conservant leur aspect réaliste.

Simulation de l'éclairage en temps-réel pour jeux vidéos

Le projet GENAC (Génération Automatique de Contenus) porte sur le développement d'outils pour le jeu vidéo : animation et rendu temps-réel. Ce projet, porté par les équipes ARTIS et EVASION de l'INRIA Rhône-Alpes, en commun avec les industriels Eden Games et Widescreen Games et le LIRIS, a été labellisé par le pôle de compétitivité Imaginove, et est financé par le Fonds de Compétitivité des Entreprises, la Région Rhône-Alpes et le Grand Lyon.

Les algorithmes de recherche développés dans le cadre de ce projet seront intégrés à une plate-forme de jeux vidéos fournie par Eden Games.

Dans le cadre de ce projet, l'INRIA Rhône-Alpes recrute un Doctorant, qui travaillera dans l'équipe ARTIS, sur la simulation en temps-réel des effets d'éclairage global.

But de la thèse : Développer un algorithme d'éclairage global en temps-réel, capable de répondre aux contraintes du jeu vidéo : affichage en temps-réel, scènes de grande taille, structure de scène imposée par le moteur de jeu, scènes animées. Cet algorithme sera intégré dans le moteur de jeu vidéo fourni par les partenaires industriels, le travail d'intégration étant effectué, en partie, par l'ingénieur recruté également dans le cadre du projet. Le travail est décomposé en sous-tâches : simulation de l'éclairage indirect reçu par un object animé au sein d'un environnement statique, placement automatique des points d'échantillonnage, simulation des variations de l'éclairage liées aux saisons.

Modelling Complex Light Sources for Image Synthesis

PhD position at GRAVIR/IMAG - Grenoble - France
Context: Image Synthesis and PhotoRealistic Rendering
In this thesis, we want to model complex light sources, such as fire, car headlights or a cristal chandelier... We envision a situation where the exact geometry of the light sources is either unknown (as in the case of fire) or too complex for a complete numerical simulation (as in the case of the cristal chandelier). We want to measure the lighting from these light sources and to store them in a compact model that expresses all the effects of the light source, either at close range or for long distances. For light sources with a spatial extension, illumination at close range will have a spatial dependancy.
We attach a great importance to the spectral content of the lighting, which we also want to store. Most light sources will also have a temporal variability. The models obtained through this study and modelling will be used in real-time rendering, global illumination simulations and virtual reality applications.
Candidates must be eligible for being granted a Marie Curie fellowship. In the following,European citizens include all people from European member states and from associated states. - See Eligibility Criteria -.

Variable Extraction in BRDFs of Composite Materials

Composite materials made of glass fibers are commonly used to create ceiling panels (the white squares in most buildings). The geometrical organisation of fibers within the gluing material, their diameter and optical properties may influence the resulting light interaction properties (e.g. the reflectance, or BRDF) to various degrees. The goal of this work is to model light interaction in such materials and try to build a set of variables that noticeably influence the BRDF. Ultimately, an analytical model may be derived to link the physical and optical characteristics of composite materials with their macro-scale reflectance properties. This work happens in collaboration with Owen's Corning (Chambery). While being hosted in INRIA Montbonnot, the candidate may have a significant level of interaction with the Owen's Corning company. This subject may be continued on a PhD in Sept. 2023....   »More information

CNN Extraction of BRDFs from Photographs

Convolutional neural networks (CNNs) have long proved their superiority in the generation/completion/compression of images. In this work we propose to use CNNs in a different context, to link a high dimensional tabulated reflectance function (BRDF) to the appearance of a material in real light conditions. An existing BRDF interpolation system will be adapted in order to generate a sufficient amount of training data. Ultimately, the resulting CNN will be used to extract BRDFs from photographs. Some experience with both C++, Cuda and CNNs is advised. This subject may be continued on a PhD in Sept. 2023. ...   »More information

Various projects for the rendering of stylized panorama maps

Panoramas are a specific type of map that transcends the boundary between cartography and art. They are excellent pictorial devices for visualizing landscapes, especially ski areas, for which the panorama has become a cartographic standard. However, very few artists or cartographers are able to draw visually pleasant and efficient panoramas. Indeed, a realistic view, or even a photograph, of a landscape does not provide the same legibility as a map. Therefore, drawing a panorama requires specific skills: the ability to understand and represent a landscape in 3D in a style that lies in between a painting and a 2D map. With the availability of full GIS (geographic information systems), we now have access to cartographic data that can be used to produce panoramas using a computer. The recent progress in computer graphics research allows the production of realistic renderings of 3D landscapes. However, the specific style of the best panoramists is still not fully reproduced by the scientific community. In this project, our goal is to design a process to produce panoramas starting from cartographic and topographic data as can be provided by IGN or OpenStreetMap. For that, we collaborate with Arthur Novat in order to understand and formalize the various steps of the drawing of a panorama. Arthur is the son of Pierre Novat who founded The Atelier Novat in the 60’s that became the French standard for mountain panoramas....   »More information

BRDF model for dry powders

We are interested in BRDF models for dry powders. These dry powders are frequently used as pigments, for example in cave paintings. They are also frequent in spatial exploration: the surface of Mars is mostly made of dry powders, as well as many asteroids. There are currently no valid BRDF models that explain the reflectance of dry powders (we have BRDF models for liquids and for solids, but not for powders). Our project here is to measure the reflectance of existing dry powders, and extract a model that connects the physical properties, such as the material and the size of the grain, with the observed properties, such as the size of the specular peak and the backscattering peak. This project will be carried in cooperation with Institut de Planétologie et d’Astrophysique de Grenoble, where there is a gonio-reflectometer for measuring dry powders, along with their spectral response. Our plan is to start with a single material, with a well measured index of refraction, to limit the sources of uncertainty, then extend to a larger range of materials

Real-time global illumination using a Latent Variable Model

The goal of the internship is to experiment with the interpolation of global illumination using a Gaussian Process latent variable model. The latent variables will be chosen so as to optimize the quality of the interpolation. Global illumination usually requires a costly calculation (as opposed to direct illumination). Based on the intuition that the two are linked by a low dimensional operator (despite the infinite dimension of the space direct and global illumination potentially belong to), we want to find low dimensional approximations of this relationship. Since linear parameterizations (using e.g. PCA) have some limits (in particular because they cause visual artifacts) we aim for non linear parameterizations. This naturally leads to looking into Gaussian processes. The student will essentially need to * get familiar with the mathematical principles of global illumination and Gaussian processes; * get familiar with the existing Maverick’s rendering platform; * implement the precomputation of images as well as the Gaussian process training in image space; * implement the real-time rendering loop in image space; * create a nice proof-of-concept demo in a non trivial geometric scene; * (optional) implement an object-space–videogame compatible–version where the light is stored into textures * (optional) discuss and experiments the advantages of different function bases to generate coefficients for direct illumination; The internship requires to be fluent in C++ and very comfortable with the acquisition of new mathematical concepts. Do not hesitate to come talk with me. If you have your own ideas about global illumination and what can be done, I'm open as well. mail: cyril.soler@inria.fr....   »More information

Inverse Procedural Textures

Procedural texture are images generated by a tree of mathematical operations/objects such as random noise, clamping, masking, normal maps, shading, etc. They are used to create stationary textures that show some structure. Existing tools such as substance (Allegorithmics, https://www.allegorithmic.com/) to design procedural textures allow a huge variety of results. The goal of this internship is to create an algorithm for recovering a procedural graph that can generate an image that is as close a possible to an input picture. This is a very difficult problem, which we will segment into simpler tasks, and leverage the recent advances in deep learning, for image comparison and image classification....   »More information

Parameterization of the Indirect Illumination Manifold

The simulation of global illumination consists in numerically solving an integral equation that expresses the equilibrium of light energy in a scene. For practical reasons, one usually separates the direct illumination, that denotes light directly comes from the light sources and bounces on a single object before reaching the camera, from the indirect illumination, which may bounces an arbitrary number of times in the scene before reaching the camera. The distribution of indirect illumination depends very smoothly on the positions of the light sources, and therefore only occupies a restricted sub-space of the full span of possible distributions of light energy in a scene, when illumination conditions are changed. Consequently, we believe that it is possible to compute a low dimensional parameterization of the manifold of indirect illumination distributions. We would like to use this parameterization to perform real-time calculations of global illumination in video games that react to the players position and actions, as well as performing relighting tasks into static images. ...   »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

Connecting Chemical / Physical Properties and Material Appearance

The aspect of a material depends on its surface characteristics and on its chemical composition. The dependency on surface characteristics, such as surface roughness, is relatively well known. The connection with the chemical composition is less well known. When a material is reduced in a powder, its color changes due to Mie scattering. Overall color depends on grain size as well as chemical composition. When the powder in included in a solvant (for oil painting), color also depends on solvant properties and concentration. Physical models explain the connection between grain size, concentration and color. The model is (obviously) non-linear. It is also computationally expensive. The goal in this project is to predict the visual properties of a mixture of hematite powder and solvant, based on the physical properties of the mixture (grain size, chemical composition, solvant). This project will be done in cooperation with Institut Néel, allowing access to the actual properties of the materials, along with its color....   »More information

Interactivel Change of Materials in Images

Our goal is to build a tool to consistently replace materials on objects in static images, where the term material denotes the properties of surfaces that define how the surface interacts with light (Typical use case: take a picture of a car, replace the car paint). The challenge in this project is to be able to extract a consistent pair of geometric properties and incident illumination in a single image from the unique knowledge of the material properties of objects in the images. This type of problem generally falls into the shape from shading category, which is known to be ambiguous. However, in our situation, we do not seek the real geometry of the objects nor the real distribution of incident light but only a consistent pair that would allow to replace the material properties while keeping the same viewing and illumination conditions. The project has already started, and we have a working pipeline for convex objects. In real life cases however, objects are not convex and require to also compute which parts of incident half-sphere of directions each pixel actually sees. We propose to compute this visibility information, in order to increase the accuracy of the extracted information. ...   »More information

Textures 3D pour l'animation aquarelle

Un des chalenges du Rendu Non Photorealsite (NPR) est de reproduire l'apparence de mediums traditionnels comme l'aquarelle, le fusain, la peinture... Une des méthodes employées consiste a reproduire certaines des caractéristiques du medium avec des textures : texture de pigments et papier pour l'aquarelle, texture de coups de pinceaux pour la peinture...

Dans le cadre d'une animation NPR, la difficulté consiste a faire bouger ces textures en accord avec les mouvements de l'animation, tout en conservant l'aspect plat et homogène du medium traditionnel. Le sujet de ce stage est d'étendre la méthode de « dynamic canvas » [2] a l'animation d'objets 3D. Dynamic canvas permet d'animer une texture de papier 2D selon les mouvements d'une camera. Le but du stage serait d'appliquer un mécanisme similaire a des textures volumiques selon le mouvements d'objets 3D. Pour cela une des pistes de recherche serait d'utiliser les recents travaux en synthese de texture [3] pour generer des textures volumique (papier, pigment, coup de pinceaux) qui respectent les contraintes de Dynamic Canvas.

Paramétrisation 3D/2D avec cohérence temporelle de lignes pour rendu expressif

Dans un rendu expressif construit de lignes à partir d'une scène 3D, les effets sont paramétrés le longs de ces lignes. Mais lors d'une animation, il est difficile de garder une paramétrisation cohérente à cause des déformations 3D des lignes mais aussi des occlusions. Le sujet de ce stage est de définir comment paramétrer une lignes issue d'un modèle 3D (silhouette par exemple) pour lui affectée une stylisation. L'idée principale est que les différents type d'effet que l'on peut appliquer à une ligne ont une paramétrisation plus appropriée que d'autre (2D/3D/autre ...). Il faut aussi définir comment faire évoluer les paramétrisations au cours de l'animation de manière cohérente. Une fois ces paramétrisations identifées, l'étudiant devra mettre en place un suivit temporelle des différentes paramétrisations et dévolopper un moteur de rendu expressif de scnène 3D avec ces paramétrisations. ...   »More information

Simulation de Peinture Animée

La peinture animée est traditionnellement effectué en photographiant une plaque de verre sur laquelle l'artiste peint à l'acrylique (généralement avec les doigts) chacune des images constituant l'animation. Le sujet proposé est la mise en place d'une simulation de ce procédé. Le rendu sera guidé par un film en entrée, vidéo ou 3D (accompagné de renseignements complémentaires tel que le flux optique) et l'utilisateur contrôlera le style du rendu en définissant les action à accomplir pour peindre l'animation. Il s'agit donc de définir un ensemble d'action que l'on peut faire pour modifier une image en s'inspirant de ce qu'un artiste peut faire à la main : ajouter de la peinture, étaler la peinture, mélanger les couleurs. Et de trouver comment combiner ces actions pour représenté le film en entrée.
