BinauralVAE: Spatial Audio Reconstruction For World Models
Luis Vitor Zerkowski, Luiz Velho
Embodied artificial intelligence has historically very much relied on visual perception, leading to a proliferation of multiple vision-centric world models. However, this reliance…
A simple and complete discrete exterior calculus on general polygonal meshes
Lenka Ptackova, Luiz Velho
Discrete exterior calculus (DEC) offers a coordinate-free discretization of exterior calculus especially suited for computations on curved spaces. In this work, we present an exten…
Neural Implicit Morphing of Face Images
Guilherme Schardong, Tiago Novello, Hallison Paz +4
Face morphing is a problem in computer graphics with numerous artistic and forensic applications. It is challenging due to variations in pose, lighting, gender, and ethnicity. This…
Multiresolution Neural Networks for Imaging
Hallison Paz, Tiago Novello, Vinicius Silva +5
We present MR-Net, a general architecture for multiresolution neural networks, and a framework for imaging applications based on this architecture. Our coordinate-based networks ar…
Neural Implicit Surface Evolution
Tiago Novello, Vinicius da Silva, Guilherme Schardong +3
This work investigates the use of smooth neural networks for modeling dynamic variations of implicit surfaces under the level set equation (LSE). For this, it extends the represent…
Exploring Differential Geometry in Neural Implicits
Tiago Novello, Guilherme Schardong, Luiz Schirmer +3
We introduce a neural implicit framework that exploits the differentiable properties of neural networks and the discrete geometry of point-sampled surfaces to approximate them as t…
Neural Implicit Mapping via Nested Neighborhoods
Vinícius da Silva, Tiago Novello, Guilherme Schardong +3
We introduce a novel approach for rendering static and dynamic 3D neural signed distance functions (SDF) in real-time. We rely on nested neighborhoods of zero-level sets of neural…
Can We Use Neural Regularization to Solve Depth Super-Resolution?
Milena Gazdieva, Oleg Voynov, Alexey Artemov +3
Depth maps captured with commodity sensors often require super-resolution to be used in applications. In this work we study a super-resolution approach based on a variational probl…
Real-time rendering of complex fractals
Vinícius da Silva, Tiago Novello, Hélio Lopes +1
This chapter describes how to use intersection and closest-hit shaders to implement real-time visualizations of complex fractals using distance functions. The Mandelbulb and Julia…
Proceduray -- A light-weight engine for procedural primitive ray tracing
Vinícius da Silva, Tiago Novello, Hélio Lopes +1
We introduce Proceduray, an engine for real-time ray tracing of procedural geometry. Its motivation is the current lack of mid-level abstraction tools for scenes with primitives in…
Ray-VR: Ray Tracing Virtual Reality in Falcor
Vinicius da Silva, Luiz Velho
NVidia RTX platform has been changing and extending the possibilities for real time Computer Graphics applications. It is the first time in history that retail graphics cards have…
Design and visualization of Riemannian metrics
Tiago Novello, Vinícius da Silva, Luiz Velho
Local and global illumination were recently defined in Riemannian manifolds to visualize classical Non-Euclidean spaces. This work focuses on Riemannian metric construction in $\ma…
How to see the eight Thurston geometries
Tiago Novello, Vinícius da Silva, Luiz Velho +1
In this expository paper, we present a survey about the history of the geometrization conjecture and the background material on the classification of Thurston's eight geometries. W…
Global Illumination of non-Euclidean spaces
Tiago Novello, Vinicius da Silva, Luiz Velho
This paper presents a path tracer algorithm to compute the global illumination of non-Euclidean manifolds. We use the 3D torus as an example.
Latent-Space Laplacian Pyramids for Adversarial Representation Learning with 3D Point Clouds
