Storing a Compressed Function with Constant Time Access
We consider the problem of representing, in a space-efficient way, a function f : S → Σ such that any function value can be computed in constant time on a RAM. Specifically, ou...

Adaptive sampling of intersectable models exploiting image and object-space coherence
We present a sampling strategy and rendering framework for intersectable models, whose surface is implicitly defined by a black box intersection test that provides the location a...

On the estimation of geodesic paths on sampled manifolds under random projections
In this paper, we focus on the use of random projections as a dimensionality reduction tool for sampled manifolds in highdimensional Euclidean spaces. We show that geodesic paths ...

Using Constraint Programming for Solving Distance CSP with Uncertainty
Many problems in chemistry, robotics or molecular biology can be expressed as a Distance CSP4 . In this paper, we propose a specific methodology for tackling uncertainties in this...
