A Full-Wave Reference Simulator for Computing Surface Reflectance

Mengqi Xia

Computing light reflection from rough surfaces is an important topic in computer graphics. Reflection models developed based on geometric optics fail to capture wave effects such as diffraction and interference, while existing models based on physical opti ...

HybridSDF: Combining Deep Implicit Shapes and Geometric Primitives for 3D Shape Representation and Manipulation

Pascal Fua, Pierre Bruno Baqué, Subeesh Vasu, Nicolas Talabot

Deep implicit surfaces excel at modeling generic shapes but do not always capture the regularities present in manufactured objects, which is something simple geometric primitives are particularly good at. In this paper, we propose a representation combinin ...

Radiative Backpropagation: An Adjoint Method for Lightning-Fast Differentiable Rendering

Wenzel Alban Jakob, Merlin Eléazar Nimier-David, Sébastien Nicolas Speierer

Physically based differentiable rendering has recently evolved into a powerful tool for solving inverse problems involving light. Methods in this area perform a differentiable simulation of the physical process of light transport and scattering to estimate ...

Graph-Based Inpainting of Disocclusion Holes for Zooming in 3D Scenes

Pascal Frossard, Pinar Akyazi

Color plus depth format allows building 3D representations of scenes within which the users can freely navigate by changing their viewpoints. In this paper we present a framework for view synthesis when the user requests an arbitrary viewpoint that is clos ...

Object Shape Approximation and Contour Adaptive Depth Image Coding for Virtual View Synthesis

Pascal Frossard, Yuan Yuan

A depth image provides partial geometric information of a 3D scene, namely the shapes of physical objects as observed from a particular viewpoint. This information is important when synthesizing images of different virtual camera viewpoints via depth-image ...

Graph-Based Interpolation for Zooming in 3D Scenes

Pascal Frossard, Pinar Akyazi

In multiview systems, color plus depth format builds 3D representations of scenes within which the users can freely navigate by changing their viewpoints. In this paper we present a framework for view synthesis when the user requests an arbitrary viewpoint ...

Encoder-Driven Inpainting Strategy in Multiview Video Compression

Pascal Frossard, Thomas Maugey

In free viewpoint video systems, where a user has the freedom to select a virtual view from which an observation image of the 3D scene is rendered, the scene is commonly represented by texture and depth images from multiple nearby viewpoints. In such repre ...

In-Network View Re-Sampling for Interactive Free Viewpoint Video Streaming

Pascal Frossard, Laura Toni

Interactive free viewpoint video offers the possibility for each user to independently choose the views of a 3D scene to be displayed at de- coder. The visual content is commonly represented by N texture and depth map pairs that capture different viewpoint ...

RD optimized auxiliary information for inpainting-based view synthesis

Pascal Frossard, Thomas Maugey

Texture and depth maps of two neighboring camera viewpoints are typically required for synthesis of an intermediate virtual view via depth-image-based rendering (DIBR). However, the bitrate overhead required for reconstruction ofmultiple texture and depth ...

Real-time textured volume reconstruction using virtual and real video cameras

Daniel Thalmann, Stéphane Gobron, Junghyun Ahn

Reconstructing objects in three dimensions (3D) has always been one of the primary tasks in the domain of computer graphics (CG). Succeeding in this task in real-time, including texture reconstruction, and with very low-cost hardware is the challenge prese ...

Mental vision : a computer graphics platform for virtual reality, science and education

Achille Peternier

Despite the wide amount of computer graphics frameworks and solutions available for virtual reality, it is still difficult to find a perfect one fitting at the same time the many constraints of research and educational contexts. Advanced functionalities an ...

ESM-Blur: Handling and Rendering Blur in 3D Tracking and Augmentation

Vincent Lepetit

The contribution of this paper is two-fold. First, we show how to extend the ESM algorithm to handle motion blur in 3D object track- ing. ESM is a powerful algorithm for template matching-based tracking, but it can fail under motion blur. We introduce an i ...

The Mental Vision framework - A platform for teaching, practicing and researching with computer graphics and virtual reality

Daniel Thalmann, Frédéric Vexo, Achille Peternier

Despite the wide amount of computer graphics frameworks and solutions available, it is still difficult to find a perfect one fitting at the same time many constraints, like pedagogical intents and user-friendliness or speed with high rendering quality and ...
