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…
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…
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…
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.
