During the last years, the topic of accessibility of cultural heritage is getting so important all around the Europe. For disseminating a research data and information, it is important to use a simple language and an effective communication. The data research produced by specialists has three formal levels： The third one of communication system aims to break barriers to reach a wide audience. The present study wants to demonstrate the role of images in the process of deductive inference by three dimensional （3D） reconstruction of cultural heritage. The case study of Federico da Montefeltro office shows how inter-disciplinary works and technological resource can help society to understand history and meaning of heritage.

The contemporary powerful mathematical software enables a new approach to handling and manipulating complex mathematical expressions and other mathematical objects. Particularly, the use of symbolic computation leads to new contribution to constructing and analyzing numerical algorithms for solving very difficult problems in applied mathematics and other scientific disciplines. In this paper we are concerned with the problem of determining multiple zeros when the multiplicity is not known in advance, a task that is seldom considered in literature. By the use of computer algebra system Mathematica, we employ symbolic computation through several programs to construct and investigate algorithms which both determine a sought zero and its multiplicity. Applying a recurrent formula for generating iterative methods of higher order for solving nonlinear equations, we construct iterative methods that serve (i) for approximating a multiple zero of a given function f when the order of multiplicity is unknown and, simultaneously, (ii) for finding exact order of multiplicity. In particular, we state useful cubically convergent iterative sequences that find the exact multiplicity in a few iteration steps. Such approach, combined with a rapidly convergent method for multiple zeros, provides the construction of efficient composite algorithms for finding multiple zeros of very high accuracy. The properties of the proposed algorithms are illustrated by several numerical examples and basins of attraction. (C) 2016 Elsevier B.V. All rights reserved.

Many vocational schools and universities offer lectures on non-stereoscopic 3D computer graphics (3DCG) animation production, as well as practical 3DCG software operation, modeling, and animation production. However, relatively few of these educational institutions provide lectures on stereoscopic 3D (S3D). To address this gap, we developed two 15-week syllabuses with educational materials, which focused on both knowledge based and skills-based education about 3DCG animation and S3D computer graphics (S3DCG) animation production, considering the potential employment of students in animation studios. Our investigation confirmed that the knowledge and skills of the subjects improved in this study, so we presented a report on the effectiveness of the educational materials for S3DCG animation production education at the Education Symposium of SIGGRAPH Asia 2015. By developing these educational materials, we reaffirmed the importance of camerawork skills education, which may be regarded as the cornerstone of 3DCG animation and S3DCG animation production. However, camerawork skills education in 3DCG animation classes remains limited in vocational schools and universities at present. We hypothesized that one of the reasons for the paucity of camerawork skills education is the lack of suitable educational materials for practical classes in the use of 3DCG software. Indeed, educational materials that allow teachers to begin camerawork skills education for 3DCG and S3DCG animation production without preparation are greatly lacking. Furthermore, modeling and character animation are regarded as essential before camerawork practice. Camerawork practice can be started immediately if sufficient educational materials are provided. The educational materials that we developed are suitable for S3DCG but also for 3DCG camerawork practice. In this study, we present the camerawork skills education and evaluation methods involved in the educational materials developed for the S3D lectures

Application of 3 D and computer graphics in film and TV animation design is analyzed in depth with discussions in this paper. In the process of the film and television animation, drama, characters and scenes are the most important elements, and they depend on each other and restrict each other. Plot is the backbone of animation creation, the role is the main body, scene design provides the showcase for characters and the plots, through the scene design will foil the plot development, animation background of time and space. The main feature of digital media art is the use of computer art, to achieve digital painting art. Digital media art major is to use digital technology and digital media to create visual art, the use of digital technology to create or performance art form, which is the core of the digital media art. This core realizes the combination of computer technology and art design, thus displaying digital media or electronic media. Under this basis, this paper presents the novel perspective on the film and TV animation design.

The computer graphics community has successfully exploited our knowledge about the human visual system and its limitations for years. The perceptual computer graphics domain is a rich research area, and the understanding of human vision mechanisms and their integration in the computer graphics processes are becoming increasingly crucial in most applications. This special issue represents a good sample of the huge diversity of challenges in the perceptual computer graphics area: aesthetics evaluation, user gaze analysis, shape perception, and the wide scope of targeted applications.
