this paper proposes a pen-based interaction system with 2D co-located haptic and visual feedback for physics education. the system combines a 3DOF pen-based planar haptic device and simulated 2D physical world based o...

Existing techniques for animation of object fracture have a basic assumption that the object materials are homogeneous while most materials in real world are heterogeneous. To solve this problem, we introduce a novel ...

Based on globally supported radial basis functions, this paper presents a hierarchical approach to 3D scattered data interpolation. Given a scattered data set distributed along a surface, we first obtain a sparse appr...

Rendering virtual objects into real scenes with real illumination can greatly increase the realism of virtual objects and the consistency between the virtual and the real. the main challenge lies in illumination estim...

In this paper, we introduce a novel 2D-3D hybrid video stabilization method which combines virtues of 2D and 3D video stabilization methods in one routine. It attempts to achieve high-quality camera motions and to ret...

In this paper, we present a novel BVH tracing method on GPU, which can achieve better SIMD utilization than traditional method. In the traditional way, thread usually sticks to a ray until the closest hit is found. Wh...

Traditional retiming processes are mostly MILP based withthe physical interconnect information less correctly reflected, thus could be very CPU intensive and incorrect on the final clock period estimations. Moreover,...

Rendering of volume caustics in participating media is often expensive, even with different acceleration approaches. Basic volume photon tracing is used to render such effects, but rather slow due to its massive quant...

Color mapping plays a critical role in visualization of time-varying data and also sets a challenge for researchers due to the consistency of mapping and great changes in time-varying data. In order to solve this prob...
