| | Eugene Zhang is an assistant professor in the School of Electrical Engineering and Computer Science at Oregon State University. He was also a recipient of the National Science Foundation CAREER award in 2006. Eugene’s research areas include computer graphics, scientific visualization, and geometric modeling. In particular, he has worked in the areas of mesh simplification and parameterization, geometry remeshing, and nonphotorealistic rendering. Recently, he has become more interested in the concepts of tensors and symmetry and how they interface with shapes. This has led to a number of publications in the areas of vector and tensor field design, as well as rotational symmetry field analysis. Eugene received his PhD degree in computer science in 2004 from Georgia Institute of Technology. In 1994, he obtained an MS degree in mathematics from Ohio State University.

Topology-oriented incremental algorithm for the robust construction of the Voronoi diagrams of disks
Lee M., Sugihara K., Kim D. ACM Transactions on Mathematical Software 43(2): 1-23, 2016. Type: Article
Voronoi diagrams are important in many applications that range from theoretical computing to computational geometry, to computer graphics and computer vision. The relatively new problem of computing the Voronoi diagram for a set of geo...

Field-aligned mesh joinery
Cignoni P., Pietroni N., Malomo L., Scopigno R. ACM Transactions on Graphics (TOG) 33(1): 1-12, 2014. Type: Article
The computer graphics field has become more physical in recent years. While images are still considered the end goal by many, there is growing interest in the graphics community to create physical objects that can be touched and held. ...

An efficient scheme for curve and surface construction based on a set of interpolatory basis functions
Zhang R., Ma W. ACM Transactions on Graphics (TOG) 30(2): 1-11, 2011. Type: Article
Curve and surface modeling based on splines or other types of basis functions is a common practice in industry. It is desirable for the basis functions interpolating the control points to be smoothly continuous, and not oscillating, an...

Investigating the role of body shape on the perception of emotion
McDonnell R., Jörg S., McHugh J., Newell F., O’Sullivan C. ACM Transactions on Applied Perception 6(3): 1-11, 2009. Type: Article
Virtual characters are used extensively in movies and games, but the effect of both motion and body shape on the portrayal of basic human emotions remains poorly understood. Some suggest that the more anthropomorphic a virtual characte...

Participating media illumination using light propagation maps
Fattal R. ACM Transactions on Graphics (TOG) 28(1): 1-11, 2009. Type: Article
Realistic rendering of semi-transparent objects, such as smoke and marble, needs to address the absorption and scattering of light as it travels through the media. This is described by the radiative transport equation, which is difficu...

Rational hypersurfaces with rational convolutions
Lávička M., Bastl B. Computer Aided Geometric Design 24(7): 410-426, 2007. Type: Article
In computer-aided design and manufacturing (CAD/M), rational hypersurfaces, such as hypersurfaces with rational parameterizations, have many desirable properties. However, convolution of two general rational hypersurfaces does not guar...

Volume conserving finite element simulations of deformable models
Irving G., Schroeder C., Fedkiw R. ACM Transactions on Graphics (TOG) 26(3): 13-es, 2007. Type: Article
The simulation of deformable objects has received much attention, thanks to a wide range of applications in animation and shape modeling. A challenging issue is how to maintain the volume of objects such as soft tissues during deformat...
