let $l$ be a completely regular frame and $mathcal{r}l$ be the ‎ring of continuous real-valued functions on $l$‎. ‎we show that the‎ ‎lattice $zid(mathcal{r}l)$ of $z$-ideals of $mathcal{r}l$ is a‎ ‎normal coherent yosida frame‎, ‎which extends the corresponding $c(x)$‎ ‎result of mart'{i}nez and zenk‎. ‎this we do by exhibiting‎ ‎$zid(mathcal{r}l)$ as a quotient of $rad(mathcal{r}l)$‎, ‎the‎ ‎...

We present a system for rendering 3D animations in the style of line drawings. We use a highly parameterized line model in order to determine the appearance of a line. This model allows us to render characteristic line deviations that remain—in contrast to existing non-photorealistic rendering systems—frame coherent. Other inconsistencies which result from intersection and visibility changes du...

This paper proposes an efficient method for the production of high quality radiosity solutions which makes use of the a-priori knowledge of the dynamic properties of the scene in order to exploit temporal coherence. The method is based on a two-pass strategy that provides user-control on the final frame quality. In the first pass, it computes a coarse global solution of the radiosities along a ...

Splatting is a classical volume rendering technique that has recently gained in popularity for the visualisation of point-based surface models. Up to now, there has been few publications on its adaptation to time-varying data. In this report, we propose a novel frame-to-frame coherent view-aligned sheet-buffer splatting of time-varying data, that tries to reduce as much as possible the memory l...

This article presents an analytic approach to study admissibility conditions related to classical full wavelet systems over finite fields using tools from computational harmonic analysis and theoretical linear algebra. It is shown that for a large class of non-zero window signals (wavelets), the generated classical full wavelet systems constitute a frame whose canonical dual are classical full ...
