Modeling and real-time rendering complex virtual scene of hydraulic engineering;

Research on real-time rendering algorithm in ship visual scenes;

Cloud simulation and real-time rendering for flight simulation;

Per Vertex Lighting has been employed many years in common for real time rendering.

To investigate real time rendering of terrain surface, improve the speed of rendering and the fidelity of simplification, the algorithm taking the distance from vertex to average plane as the error metric and progressive meshes based dynamic simplification was used, which provided view dependent simplification of the model.

The efficient visibility culling method is one of the important research aspects of real time rendering of complexle dynamic scene.

But there is little research on fluid artistic style in non-photorealistic rendering(NPR).

Realistic rendering of 3D terrain scenes is always a challenging subject.

Efficient method of real-time realistic rendering is urgently required by increasing applications, such as virtual reality, dynamic simulation, real-time visualization, etc.

Since 1990 s,Non-photorealistic rendering have become one of the hot spots of the computer graphics research.

The animation rendering technology can be approximately divided into two categories: photorealistic rendering technology and non-photorealistic rendering (NPR) technology.

Techniques of programmable vertex shader and pixel shader have been integrated in newly developed graphics hardware armed with powerful Graphics Processing Unit(GPU) in recent years, and as a result, real-time volume rendering can be implement.
