This work introduces a new technique for highly detailed, interactive liquid simulations. Similar to the mode-splitting method (used e.g. in oceanography), we separate the simulation of the low-frequency liquid flow and the high-frequency free surface ...

Visual simulation of natural erosion on terrains has always been a fascinating research topic in the field of computer graphics. While there are many algorithms already developed to improve the visual quality of terrain, the recent simulation methods ...

At the moment the noise functions available in a graphics programmer's toolbox are either slow to compute or they involve grid-line artifacts making them of lower quality. In this paper we present a real-time noise computation with no grid-line ...

The paper introduces a new approximate method for rendering translucent materials. We represent the surface around a point to be rendered in Monge's form using principal curvatures. The subsurface reflectance equation in the dipole diffusion ...

For wireless network based graphics applications, a key challenge is how to efficiently transmit complex 3D models over bandwidth-limited wireless channels. Recently, several view-dependent 3D progressive mesh transmission schemes have been proposed, ...

In this work, we analyse the effect of network parameters on the judged usability of a collaborative virtual environment. Participants were trained to find the exit of a virtual maze by a trainer, which guided the exploration of the virtual space. An ...

A number of popular global illumination algorithms uses density estimation to approximate indirect illumination. The density estimate is performed on finite points -- particles -- generated by a stochastic sampling of the scene. In the course of the ...

In this paper we present a method to combine several micro-facet based surface layers into a single unified, expressive BRDF model that is easy to use. The restriction to micro-facet based layers constitutes no loss of generality, since both perfectly ...

We revisit the assumptions behind traditional image compositing techniques. By analysing the process we separate the colour operations from those for coverage and show that this usefully leads to a more general compositing equation than previously used. ...

Developments in the graphics discipline called realistic image synthesis are in many ways related to the historical development of theories of light. And theories of light will probably continue to inspire the ongoing search for realism in graphics. To ...

Because of their geometric complexity, high resolution 3D models, either designed in high-end modeling packages or acquired with range scanning devices, cannot be directly used in applications that require rendering at interactive framerates. One clever ...

A motion trend analysis method is proposed to reconstruct human motion from un-calibrated monocular video. In this paper, relocation of human subject is the main concern, which is one of the most difficult parts in motion reconstruction and critically ...

In this paper, we present a new method for surface-based shape reconstruction from a set of silhouette images. We propose to project the viewing cones from all viewpoints to the 3D space and compute the intersections that represent the vertices of the ...

This paper describes an interactive method for generating a model of a scene from image data. The method uses the camera parameters and point cloud typically generated by structure-and-motion estimation as a starting point for developing a higher level ...

In blendshape-based facial animation, two main approaches are used to create the key expressions: manual sculpting and statistically-based techniques. Hand-generated expressions have the advantage of being intuitively recognizable, thus allowing ...

In this paper, we present a novel user interface design for mobile games using its built-in camera. It is motivated by the problem of limited number of keys on the small keypad of mobile devices. We implement two different ways, with and without the use ...
