Editorial

Dear colleagues, This special issue of CGG electronic journal is devoted to the ideas originally presented in the scope of GraphiCon'2004 conference (www.graphicon.ru/2004) and further selected by the international juries to be extended and presented here. Certainly, the papers were greatly improved due to feedback received at the conference, so we hope you will find them even more interesting. Although we have five best papers included in this issue, they appear to be a joint result of authors from many different countries including China, Russia, Netherlands, Japan and Finland. They also present quite large diversity of topics including biomechanics and character animation, intellectual image data processing, 3D modeling and geometry optimization for fast rendering. We hope you will enjoy reading the papers, Dr. Denis Ivanov, GraphiCon'2004 Co-Chair
