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…
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.
Discrete Line Fields on Surfaces
Tiago Novello, João Paixão, Carlos Tomei +1
Vector fields and line fields, their counterparts without orientations on tangent lines, are familiar objects in the theory of dynamical systems. Among the techniques used in their…
