A Trajectory-Preserving Synchronization Method for Collaborative Visualization (2006)
Journal Article
Li, L., Li, F., & Lau, R. (2006). A Trajectory-Preserving Synchronization Method for Collaborative Visualization. IEEE Transactions on Visualization and Computer Graphics, 12(5), 989-996. https://doi.org/10.1109/tvcg.2006.114

In the past decade, a lot of research work has been conducted to support collaborative visualization among remote users over the networks, allowing them to visualize and manipulate shared data for problem solving. There are many applications of colla... Read More about A Trajectory-Preserving Synchronization Method for Collaborative Visualization.

Efficient Rendering of Deformable Objects for Real-time Applications (2006)
Journal Article
Cheung, G., Lau, R., & Li, F. (2006). Efficient Rendering of Deformable Objects for Real-time Applications. Computer Animation and Virtual Worlds, 17(1), 69-81. https://doi.org/10.1002/cav.71

Deformable objects can be used to model soft objects such as clothing, human faces and animal characters. They are important as they can improve the realism of the applications. However, most existing hardware accelerators cannot render deformable ob... Read More about Efficient Rendering of Deformable Objects for Real-time Applications.

Multi-server support for large scale distributed virtual environments (2005)
Journal Article

VSculpt : a distributed virtual sculpting environment for collaborative design (2003)
Journal Article
Li, F., Lau, R. W., & Ng, F. (2003). VSculpt : a distributed virtual sculpting environment for collaborative design. IEEE Transactions on Multimedia, 5(4), 570-580. https://doi.org/10.1109/tmm.2003.814795

A collaborative virtual sculpting system supports a team of geographically separated designers/engineers connected by networks to participate in designing three-dimensional (3-D) virtual engineering tools or sculptures. It encourages international co... Read More about VSculpt : a distributed virtual sculpting environment for collaborative design.

Incremental polygonization of deforming NURBS surfaces. (1999)
Journal Article
Li, F., & Lau, R. (1999). Incremental polygonization of deforming NURBS surfaces. Journal of graphics tools (2012), 4(4), 37-50. https://doi.org/10.1080/10867651.1999.10487514

Nonuniform rational B-splines (NURBS) are a powerful tool to model deformable objects. Their shapes can be easily modified by moving the control points. A common method used to render these objects is polygonization. However, the polygonization proce... Read More about Incremental polygonization of deforming NURBS surfaces..
