Interactive visualization of very large volume data has been recognized as a task requiring great effort in variety science and engineering fields. In particular, such usually places considerable demands on run‐time memory space. this paper, we present an effective 3D compression scheme for interactive data, that exploits the power wavelet theory. designing our method, have compromised between two important factors: high ratio fast random access ability.

This paper presents an efficient algorithm called Hermite interpolation, for constructing low-degree algebraic surfaces, which contain, with C 1 or tangent plane continuity, any given collection of points and space curves having derivative information. Positional as well constraints on implicitly defined surface are translated into a homogeneous linear system, where the unknowns coefficients polynomial defining surface.

This paper presents a new 3D RGB image compression scheme designed for interactive real-time applications. In designing our method, we have compromised between two important goals: high ratio and fast random access ability, tried to minimize the overhead caused during run-time reconstruction. Our technique is suitable applications wherein data are accessed in somewhat unpredictable fashion, performance of decompression necessary. The experimental results on three different kinds images from...

In this paper, we extend the well-accepted particle level set method an attempt to integrate dynamic behavior splashing easily into a animation system. Massless marker particles that escape from main body water, spite correction, are transformed represent subcell-level features hard capture with limited grid resolution. These physical then moved air through simulation system...

A plenoptic function is a parameterized describing the flow of light in space, and has served as key idea building some recent image based rendering systems. The paper presents new representation scheme, called spherical field, function, that on spheres. While methods using coordinates are thought to require substantially more computation than those planar or cylindrical coordinates, we show spheres can also be used efficiently representing resampling light. Our algorithm different from...

Abstract Immersive video stored in multiview video-plus-depth format can provide viewers with vivid immersive experiences. However, rendering such real time environments remains a challenging task due to the high resolution and refresh rate demanded by recent extended reality displays.
