Foreword to the special section on the Spring Conference on Computer Graphics 2015 (SCCG'2015)

[Excerpt] It is our pleasure to present this special section of Computers & Graphics (C&G), featuring the selected best papers presented at the 31st Spring Conference on Computer Graphics 2015 (www. sccg.sk), which was held April 22–24, 2015 in Smolenice, Slovakia. The venue is probably the oldest regular annual meeting of computer graphics in Central Europe, covering all relevant innovative ideas in computer graphics, image processing and their applications. The philosophy of SCCG is to bring together top experts and young researchers in CG in order to support a good and sustained communication channel for East–West European exchange of prospective ideas.

Rendering of Japanese Artcraft

We present several methods for simulation of Japanese lacquer ware, a prominent Far East Asian handicraft art. We consider two most popular kinds of Japanese lacquer ware made by the makie and nashiji techniques

Animation of Biological Organ Growth Based on L-systems

In contrast with the growth of plants and trees, human organs can undergo signi cant changes in shape through a variety of global transformations during the growth period, such as bending or twisting. In our approach, the topology of a human organ is represented by a skeleton in the form of a tree or cycled graph. The length of skeleton growth can be simulated by an algebraic L-system that also produces discrete events. The paper shows how to include global transformations into the formalism of L-systems to obtain a continuous process. The shape of the organ is approximated by a number of ellipsoidal clusters centredatpoints on the skeleton. The proposedgrowth model of the organ continually responds to the positional changes of surrounding organs, thereby changing the organ shape locally. In our study, the stomach of a human embryo is used for the demonstration of organ development, and the methodology employed is also applicable to the animation of animal organs and their development. 1
