Currently, most of multi-touch surface tables do not provide any tactile feedback to the users. In this paper, a multi-touch surface table with tactile feedback is proposed. The proposed surface table provides the users with the ability of multi-point tactile feedback with variant patterns and levels of vibrations. A webcam is used to capture all finger-touch images as system inputs using compu...

A long-standing challenge in geometric modeling is providing a natural, intuitive interface for making local deformations to 3D surfaces. Previous approaches have provided either interactive manipulation or physical simulation to control surface deformations. In this paper, we investigate combining these two approaches with a painting interface that gives the user direct, local control over a p...

Surface visualizations of fMRI provide a comprehensive view of cortical activity. However, surface visualizations are difficult to generate and most common visualization techniques rely on unnecessary interpolation which limits the fidelity of the resulting maps. Furthermore, it is difficult to understand the relationship between flattened cortical surfaces and the underlying 3D anatomy using t...

Engineers and scientists from many fields are using three-dimensional reconstruction for visualization and analysis of physical and abstract data. Beyond observing the recreated objects in artificial space, it is desirable to develop methods that allow one to interactively manipulate and alter the geometry in an intuitive and efficient manner. In the case of medical data, a baseline interactive...

Many interactive 3D applications involve capturing, representing and reproducing the appearance of real objects. The surface light field represents the appearance of a solid object under static lighting by sampling the radiance along rays parametrized by surface position and direction. An implementation can represent this data as highresolution surface geometry, coupled with multiple texture ma...

In this paper, we propose a new shape editing algorithm based on the concept of explicit surface flow. The basic idea is: given an input polygonal model, the user interactively defines a distance field around regions of interest of the model, the locally or globally affected regions of the model will then automatically deform according to the userdefined distance field. The deformation behavior...

Particle-based simulation methods are gaining popularity for creating animations of physical phenomena such as fluids and melting solids. Extracting and visualizing an explicit surface corresponding to the volume of particles is however a difficult and time-consuming task, especially with increasing particle set sizes. In this paper, we present a novel interactive rendering algorithm for raster...
