We present a novel approach for real-time rendering of transparent objects with multi-scale rough refraction under all-frequency environmental lighting. In our rendering system, the normal distribution function (NDF) of the surface bumps is expressed via mixtures of von Mises-Fisher (vMF) distributions, while the corresponding perturbation of refracted rays (RDF) can be approximated as a spherical...
We introduce a general technique of dynamically augmenting physical models. Using a handheld projector attached with an RGBD camera, we map the physical model with corresponding textures, and develop a real-time dynamic spatial augmented reality (SAR) system named iSarProjection. Compared to traditional huge and complex tracking system, this technique, based on KinectFusion, supports precise registration...
We propose an interactive sketching tool for exploring image database, called InSide. Our main contribution is a new solution of interactive image exploration that dynamically adapts to users' sketching and provides mixed feedback. A position-aware matching approach is proposed for InSide in order to support translation-free sketch searching. Based on demonstrated results, our method outperforms state-of-the-art...
As commercial projectors become cheaper and smaller, appearance modification technique which employs projection display technologies now impact more areas including culture heritage, product design and architectural relighting. In this paper, we introduced a new method that use superimposed projection to modify the appearance of a non-planar textured object in real-time. Both the geometric and the...
A system for live high quality surface reconstruction using a single moving depth camera on a commodity hardware is presented. High accuracy and real-time frame rate is achieved by utilizing graphics hardware computing capabilities via OpenCLTM and by using sparse data structure for volumetric surface representation. Depth sensor pose is estimated by combining serial texture registration algorithm...
Virtual Labels are used in computer graphics applications to represent textual information arranged on geometric surfaces. Such information consists of names, numbering, or other relevant data that need to be noticed quickly when a user scans the objects in the scene. This paper focuses on the so-called massive models, which have a large number of geometric primitives whose rendering presents a high...
In this paper, we propose a data-driven approach for realistic deformation of articulated meshes: the wide availability of pose data makes such an approach feasible. We use multiple reference models, combined with a fast linear blending skinning (LBS) method in local spaces. By exploiting information from the reference models, realistic deformation is achieved, yet with computational efficiency comparable...
