The traditional design method of 3D animation modelings, by which can obtain attractive and precise 3D animation modelings, is to use three-dimensional modeling software such as Maya or 3D Max to draw directly. However, this method is faced with many problems, for instance, the lack of creativity, long design circle, high production costs, etc. For the problem of the lack of creativity, the reason is that animation designers are often subject to the limitation of the existing modelings and design concepts in the design process, therefore, they can not design creative modelings which are attractive and unforgettable enough. [For the problem of long design circle and high production costs, the reason is that although the 3D animation software are powerful, to skillfully master them not only requires users to have knowledge of computer technology and aesthetics at the same time, but also need a long learning process of modeling. Moreover, it takes the designers a lot of time and energy to design, draw and complete each modeling, and this will undoubtedly extend the design circle and increase the costs to some extent. Therefore, how to quickly and automatically generate creative 3D animation modelings has become a research focus of the present computer-aided creative design.

Abstract – Augmented reality (AR) technology facilitates augmentation of current views with digital artifacts, such as information, three-dimensional objects, audio, and video. Mixed reality (MR) represents an enhanced version of AR, where advanced spatial mapping is used to anchor digital artifacts in physical space. Using MR technology, digital artifacts can be more closely integrated into the natural environment, thereby transcending physical limitations and creating enhanced blended learning environments. In this paper, we propose an approach for integration of MR technology into engineering education. Specifically, we propose to integrate Microsoft HoloLens into a first-year course on data structures and algorithms to improve student engagement and learning outcomes. In the pilot study, students were assigned to implement A* algorithm and then given a chance to visualize their implementation using Microsoft HoloLens. The feedback provided by students indicated increased engagement and interest in graph-based path-finding algorithms as well as MR technology.

In Augmented Reality systems, virtual objects are combined with real objects, both three dimensional, interactively and at run-time. In an ideal scenario, the user has the feeling that real and virtual objects coexist in the same space and is unable to differentiate the types of objects from each other. To achieve this goal, research on rendering techniques have been conducted in recent years. In this paper, we present a Systematic Literature Review aiming to identify the main characteristics concerning photorealism in Mixed and Augmented Reality systems to find research opportunities that can be further exploited or optimized. The objective is to verify if exists a definition of photorealism in Mixed and Augmented Reality. We present a theoreticalfundamental over the most used methods concerning realism in Computer Graphics. Also, we want to identify the most used methods and tools to enable photorealism in Mixed and Augmented Reality systems.

Abstract. C-arm X-ray imaging systems are widely applied in surgeries. Overlaying X-ray with optical images during the surgery has been shown to be an efficient approach. Moreover, overlaying needed data from different modalities in an augmented reality (AR) manner can improve the accuracy of surgical procedures, decrease the variability of surgical outcomes, reduce trauma to the critical structures, increase the reproducibility of surgeons’ performance, and reduce radiation exposure. C-Arm geometric calibration and recovering the C-arm pose are essential for surgical navigation and AR applications in operating rooms. Therefore, in this paper, existing researches for calibration and pose estimation of C-arm devices in surgical AR applications are evaluated from photogrammetric point of view. Then, a proposed marker-based method for C-arm pose estimation is introduced. For this purpose, a marker is designed to facilitate tracking and pose estimation in mixed reality based on golden section principle, and perspective invariants such as cross-ratios, collinearity, and intersection. Moreover, a procedure is also proposed for fast determination of these fiducial markers. The experiments show benefits of such a structure which has a limited occlusion with consistency to different conditions such as narrow field of view and at the same time, even in images with high projectivity. It also results that the distortion correction step is important and the effect of distortion of X-ray images can cause inconsistency in the perspective invariants.

Jajanan Pasar is a term for Indonesian traditional snacks, a part of Indonesian culture that has been forgotten by the young generation. Three-dimensional (3D) animation and Augmented Reality (AR) can be used as a medium for introducing this culture to children aged 4 to 6. Because, in AR, visual between real and digital world can be altered, so the visual of 3D models can be enjoyed from various sides. This study focuses on 3D visualization for AR that packaged in 5 set of puzzles. Each piece has an illustration of the ingredients for making 5 kinds of Jajanan Pasar, after all, puzzle pieces of each set get arranged, a new 3D model of traditional snacks will be appeared. The data was collected using literature and existing studies method. The purpose of this study is to create an optimal 3D visualization for AR that will be applicated for mobile devices. Conclusion from this project are the polygon count and target marker’s quality, affect the appearance of the 3D model in AR form.

Color appearance models have been extensively studied for characterizing and predicting the perceived color appearance of physical color stimuli under different viewing conditions. These stimuli are either surface colors reflecting illumination or self-luminous emitting radiations. With the rapid development of augmented reality (AR) and mixed reality (MR), it is critically important to understand how the color appearance of the objects that are produced by AR and MR are perceived, especially when these objects are overlaid on the real world. In this study, nine lighting conditions, with different correlated color temperature (CCT) levels and light levels, were created in a real-world environment. Under each lighting condition, human observers adjusted the color appearance of a virtual stimulus, which was overlaid on a real-world luminous environment, until it appeared the whitest. It was found that the CCT and light level of the real-world environment significantly affected the color appearance of the white stimulus, especially when the light level was high. Moreover, a lower degree of chromatic adaptation was found for viewing the virtual stimulus that was overlaid on the real world.
