Ray-Tracing Triangular Trimmed Free-Form Surfaces
This paper presents a new approach to rendering triangular algebraic free form surfaces. A hierarchical subdivision of the surface with associated tight bounding volumes provides ...

Characterizing Indoor Wireless Channels via Ray Tracing, and Validation via Measurements
Abstract—We investigate the reliability of radio channel simulators in capturing the important properties of radio channels throughout a well-specified environment. Indoor envir...

Carving from Ray-Tracing Constraints: IRT-Carving
We present a new algorithm for improving an available (conservative) estimate of the shape of an object using constraints from ray-tracing. In particular, we exploit incoherences ...

Building World Models by Ray-Tracing within Ceiling-Mounted Positioning Systems
Context-aware computing in location-aware environments demands the combination of real world position with a computational world model to infer context. We present a novel approach...

Volumetric Ray Tracing
We introduce a framework for texturing volumetric objects with displacement maps and texture maps, which are introduced as volume modeling tools. In this framework, an implicit-to...
