for Smoothed Particle Hydrodynamic Fluid Simulation,”
(Unpublished, Submitted to VisPacific 2009)
Abstract:
Animating fluid like water, smoke and fire by
physics-based simulation is increasingly important in visual effects and is
starting to make an impact on real-time games. On one hand, simulating the
realistic behavior of fluid requires a lot of computational resources. And
particle-based approaches, like Smoothed Particle Hydrodynamics (SPH), can
provide a relatively accurate fluid model in reasonable time and become more and
more popular recently. On the other hand, the fast development of GPU enables
tremendous acceleration for a large number of physical simulations. In this
paper, we present a GPU-based approach for fast particle-based SPH fluid
simulation, to leverage the highly parallelized computing technology of
programmable graphics hardware. And the experimental result shows that we gain
remarkable acceleration by using GPU.

Hangzhou, China, 2008, pp. 741-744.
Abstract:
A stereo panorama consists of a pair of panoramic images, where one panorama is
for the left eye, and the other panorama is for the right eye. The disparity
between two panoramas provides parallax which enables stereo sense to the
viewer. A stereo panoramic pair provides a stereo sensation up to a full 360
degrees. A typical stereo panorama can be created by mosaicing images from a
rotating camera. However, the conventional image mosaicing process is often done
offline. And once the mosaicing stage is finished, the disparity between two
panoramas is fixed, which means that the baseline between two eyes cannot be
changed. In order to support a dynamic baseline, the mosaicing process should be
performed in run-time. In the paper, we discuss the theory of stereo sensation,
and the algorithm of carrying out runtime panorama image mosaicing to support
baseline change and parallax real-time adjustment.

Video Card With A Single PC", (to appear in DEA 2008)
Abstract:
Stereo panorama
roaming is a technology of virtual reality. Based on pictures taken from
different prospective, it can exhibit reliable circumstance information,
generate parallax, formulate stereoscopic sense, provides perfect man-machine
interaction and immersive user experience. To display stereo panorama needs two
or more display devices which require special software and hardware support.
However, along with the development of video card technology, multi-head video
cards begin to become popular. In this paper, we present a Direct3D based
software/hardware solution which leverage multi-head video card to display
stereo panorama. We also developed a prototype of stereo panorama system using
the technology in this paper.

XAML format”, Bachelor Graduate Thesis, Tongji University 2007
Abstract:
Along with the release of .Net Framework 3.0, Microsoft
introduced a new software development model and a new mark up
language, XAML (Extensible Application Markup Language). XAML
tags are used to describe user interfaces, 2D or 3D graphics; it
separates the user interface from the implementation behind it.
In future, XAML will be extensively used in desktop application
or web application. So there is need to convert the existed 2D
or 3D data model format in the XAML format, to make the
development of application or web publish to be more convenient.
In this paper, we propose automatic approaching to convert an
AutoCAD drawing into XAML code. Using ObjectArx to develop an
AutoCAD application and extend AutoCAD to leverage the WPF
API(s) to export the AutoCAD drawing's primitives into XAML tags
in order to use them directly in desktop or web application
development.
