BIOBILIOGRAPHY

Chunhui Mei was born in April, 1977, Wuhu, Anhui Province P.R.China. He received Master degree from the Mechanics Department of Zhejiang University in 2001. And then he continued his study in Computer Science and Engineering Department of Zhejiang University. In June, he got his Ph. D degree at State Key Lab of CAD&CG , Zhejiang University , under the supervision of Pro Jiaoying Shi .

RESEARCH & PUBLICATION

I major in Computer Graphics and Virtual Reality. Since 2002, I participated a chinese NSF project, Image-based Modelling and Rendering in Virtual Reality, which began at 2001 and still carries on. I have finished some work on Image-based Rendering technique for walkthrough system. And some work on the Bi-directional Texture Function was accomplished afterwards, which gives the realistic rendering result in real-time. Another job completed is an improved surface reconstruction algorithm from unorganized sampling points. I also have done some work on the physically based modelling, which simulates the deformation and movement of soft objects for VR application. The projects proceeding are image-based simplification and acceleration of rendering, and Precomputed Radiance Transfer.

Precomputed Radiance Transfer

PRT is real-time global illumination rendering method developed recently for rendering static scene under dynamic lighting. We proposed a new PRT method for real-time rendering soft shadows and inter-reflections in dynamic scene.

Image-based Simplification and Acceleration of Rendering

The simplification is based on Billboard Clouds, which is an extreme image-based simplification method.

Bidirectional Texture Function

We focus on the representation, synthesis, and rendering of BTF. A new efficient BTF model is introduced for synthesizing real-world texture surfaces onto virtual objects.

Texture Synthesis on Arbitrary Surface

The seamless texture generation on suface is an interesting project. We proposed a fast synthesis method.

Image-based Rendering

Demo Movie 4.1MB (Microsoft mpeg4 AVI)

We introduce a new IBR technique based on 3D Plenoptic Function for walkthrough system rendering. This method cooperates with rough scene geometry model, so it can reduces sampling data amount and corrects large distortion in depth.

Surface Reconstruction

We reconstruct the surface from dense sampling points with an improved Co-Cone structure based method.

Physically based Modeling

Improved Physically-based modeling techniques based on Boundary Element Method are proposed for simulation of soft object deformation and movement. These methods can reduce calculation load by adaptive Level of Detail technique, and simulate large deformation realistically by approximate nonlinear Boundary Element Method.
