#BLACKSMITH3D SUBDIVISION SURFACES 2017 PC#
He has served as the PC member of international conferences including Geometric Modeling and Processing, Shape Modeling International and CAD/Graphics. He has published 90+ papers and more than 30 papers were published in international mainstream journals on computer graphics such as ACM TOG, IEEE TVCG, CGF, CAGD, C & G and TVC etc. From 2002 to 2008, he visited the City University of Hong Kong Several times for collaborative research. He became a teacher of the department of mathematics, Guangxi College of Education in 1990. He was a lecturer and then associate professor from 1994 to 1998 in the School of Computer and Information Engineering, Guangxi University, Nanning, China. We are also studying dynamic geometry processing combining geometric, image and video information.ĭigital geometry processing: Include various topics, 3D shape deformation, 3D shape interpolation, subdivision-based modeling, mesh geometry processing, topology editing, and mesh optimization.īefore joining in the School of Computer Science and Engineering, South China University of Technology in 2003, he worked as a postdoctoral researcher in State Key Lab of CAD&CG, Zhejiang University (From Sep., 2001 to Sep. Image and video editing: We have conducted research on image resizing, matting, color transfer, video interpolation and stabilization. We are also interested in shape editing and deformation of meshes based on these representations.

(2001) Institute of Computing Technology, Chinese Academy of Sciences, Beijing, China, June 2001 (Ph.D. The structure that is modeled is the control cage for the subdivided model, it’s not just a modifier that when added just somehow makes the model better.Ph.D. The use of subdivision surfaces is planned, including the subdivision level. There are also severely non-planar polygons Īnd there are non-manifold errors because of two interior faces
Yours has n-gons and triangles that make a different pattern when subdivided Subdivisions are predictable with quadrilateral face structure. When using Catmull-Clark to refine the forms by adding more geometry and approximating the surface again, showing the subdivision on the control cage doesn’t show the actual vertex positions and if not before, building a model structure with that on you eventually end up with a mess because of that. The modifier is set to be visible in edit mode, and also on the control cage. That’s added geometry that doesn’t do anything to improve the form so it’s useless. With that it puts 4x more geometry on each subdivision level (with quadrilateral faces), optimally without changing the surface at all. The modifier is set to simple, which subdivides all faces without deforming it.
