A PDE Approach to Data-driven Sub-Riemannian Geodesics in SE(2) [PDF]
We present a new flexible wavefront propagation algorithm for the boundary value problem for sub-Riemannian (SR) geodesics in the roto-translation group $SE(2) = \mathbb{R}^2 \rtimes S^1$ with a metric tensor depending on a smooth external cost $\mathcal{

Spacelike surface families interpolating common asymptotic curves in Minkowski 3-space
In this paper, we propose a method for constructing families of spacelike surfaces in Minkowski 3-spaceE13 that share Bertrand curves as asymptotic curves.

A Stable Higher Order Space-Time Galerkin Scheme for Time Domain Integral Equations
Stability of time domain integral equation (TDIE) solvers has remained an elusive goal for many years. Advancement of this research has largely progressed on four fronts: (1) Exact integration, (2) Lubich quadrature, (3) smooth temporal basis functions ...

An Overview of Rendering from Volume Data --- including Surface and Volume Rendering [PDF]
Volume rendering is a title often ambiguously used in science. One meaning often quoted is: `to render any three volume dimensional data set'; however, within this categorisation `surface rendering'' is contained.

Multi-cultural visualization : how functional programming can enrich visualization (and vice versa) [PDF]
The past two decades have seen visualization flourish as a research field in its own right, with advances on the computational challenges of faster algorithms, new techniques for datasets too large for in-core processing, and advances in understanding ...

Deterministic Global 3D Fractal Cloud Model for Synthetic Scene Generation
This paper describes the creation of a fast, deterministic, 3D fractal cloud renderer for the AFIT Sensor and Scene Emulation Tool (ASSET). The renderer generates 3D clouds by ray marching through a volume and sampling the level-set of a fractal function.

Classification-based point cloud denoising and 3D reconstruction of roadways
ObjectiveThe point cloud denoising and 3D reconstruction of roadways serve as a key step in the digital modeling and analysis of roadways. However, the conventional algorithm based on single filtering fails to effectively remove the noise at varying ...

Immersive VR Visualizations by VFIVE. Part 1: Development
We have been developing a visualization application for CAVE-type virtual reality (VR) systems for more than a decade. This application, VFIVE, is currently used in several CAVE systems in Japan for routine visualizations.

A parallel Heap-Cell Method for Eikonal equations [PDF]
Numerous applications of Eikonal equations prompted the development of many efficient numerical algorithms. The Heap-Cell Method (HCM) is a recent serial two-scale technique that has been shown to have advantages over other serial state-of-the-art ...
