Abstract:

This paper describes an interactive art installation titled "drop." It is the first artwork using the Waterdrop Projection-Mapping (WPM) system, which animates levitating waterdrops. With this artwork, the anno lab team infuses physical characteristics into computer graphics and materializes them as tangible pixels. WPM consists of a waterdrop generator and an ultra high-speed projector. The team uses an ultra high-speed projector to cast stroboscopic spotlights mapping on waterdrops to create an optical illusion of animating each waterdrop individually. This is a new technique to show computer animation by animating levitating waterdrops. This technique explores a new horizon to create animations with tangible pixels that the viewer can touch physically.

Abstract:

Self-animating image of flow through repeated asymmetric patterns (RAPs) is an innovative approach for creating illusory motion using a single image. In this paper, we present a smooth cyclic variable-speed RAP animation model that emulates orthogonal advancing waves from a geometry-based flow representation. It enables dense, accurate visualization of complex real-world flows using animated streamlines of an elegant placement coupled with visually appealing orthogonal advancing waves. The animation model first performs velocity (magnitude) integral luminance transition on individual streamlines. Then, inter-streamline synchronization in luminance varying along the tangential direction is imposed. Next, tangential flow streaks are constructed using evenly spaced hue differing in the orthogonal direction. In addition, an energy-decreasing strategy is proposed that adopts an iterative yet efficient procedure for determining the luminance phase and hue of each streamline in HSL (hue, saturation, and lightness or brightness) color space. To increase the contrast between flow streaks, adaptive luminance interleaving in the direction perpendicular to the flow is further applied. We demonstrate the effectiveness of the animation model using some synthetic and real flows. Color figures, images, and accompanying animations are available at http://graphics.csie.ncku.edu.tw/flowvis .

Abstract:

This paper introduces a data-driven approach for human locomotion generation that takes as input a set of example locomotion clips and a motion path specified by an animator. Significantly, the approach only requires a single example of straight-path locomotion for each style expressed and can produce a continuous output sequence on an arbitrary path. Our approach considers quantitative and qualitative aspects of motion and suggests several techniques to synthesize a convincing output animation: motion path generation, interactive editing, and physical enhancement for the output animation. Initiated with an example clip, this process produces motion that differs stylistically from any in the example set, yet preserves the high quality of the example motion. As shown in the experimental results, our approach provides efficient locomotion generation by editing motion capture clips, especially for a novice animator, at interactive speed.

Abstract:

Space mean speed cannot be directly measured in the field, although it is a basic parameter that is used to evaluate traffic conditions. An end-to-end convolutional neural network (CNN) was adopted to measure the space mean speed based solely on two consecutive road images. However, tagging images with labels (=true space mean speeds) by manually positioning and tracking every vehicle on road images is a formidable task. The present study was focused on naïve animation images provided by a traffic simulator, because these contain perfect information concerning vehicle movement to attain labels. The animation images, however, seem far-removed from actual photos taken in the field. A cycle-consistent adversarial network (CycleGAN) bridged the reality gap by mapping the animation images into seemingly realistic images that could not be distinguished from real photos. A CNN model trained on the synthesized images was tested on real photos that had been manually labeled. The test performance was comparable to those of state-of-the-art motion-capture technologies. The proposed method showed that deep-learning models to measure the space mean speed could be trained without the need for time-consuming manual annotation.

Abstract:

Text in articles is based on expert opinion of a large number of people including the views of authors. These views are based on cultural or community aspects, which make extracting information from text very difficult. This paper introduced how to utilize the capabilities of a modified graph-based Self-Organizing Map (SOM) in showing text similarities. Text similarities are extracted from an article using Google's PageRank algorithm. Sentences from an input article are represented as graph model instead of vector space model. The resulted graph can be shown in a visual animation for eight famous graph algorithms execution with animation speed control.The resulted graph is used as an input to SOM. SOM clustering algorithm is used to construct knowledge from text data. We used a visual animation for eight famous graph methods with animation speed control and according to similarity measure; an adjustable number of most similar sentences are arranged in visual form. In addition, this paper presents a wide variety of text searching. We had compared our project with famous clustering and visualization project in term of purity, entropy and F measure. Our project showed accepted results and mostly superiority over other projects.

Abstract:

Abstract.The modality principle claims that animations are more effective with narration than with on-screen text. However, the cognitive mechanisms that explain the effect are not entirely clear yet. Two issues were investigated in the current study. Experiment 1 focused on the different channel assumption that narration and on-screen text tax working memory differently. Sixty participants studied an animation on the formation of lightning ( Mayer & Moreno, 1998 ; Moreno & Mayer, 1999 ) with either narrated text or on-screen text. Afterwards, mental effort, retention and transfer were measured. Also, half the participants got a counting task that taxed the phonological loop in working memory. The hypothesis was that the counting task would affect learning in the narrated condition more than in the on-screen text condition. The results did not show such an interaction, with the loading task affecting both conditions equally. Surprisingly, no main effect of modality was found either. Nevertheless, the results do not support the different channel assumption as an explanation for the modality effect. The second experiment tested whether the modality effect could be the result of split attention in the on-screen text condition, aggrevated by a lack of time to integrate screen text and animation. Seventy participants studied the same animation as in Experiment 1, but this time both modality of text and speed of animation were varied. We expected the strongest modality effect in the fast conditions, and a less strong effect in the slow conditions. However, no differences were found on any of the dependent measures. The double failure to replicate the modality effect and the lack of evidence for the different channels explanation raises doubt on its theoretical rationale and limits its practical use as a design principle.

Abstract:

Purpose of the study: This study aims to identify the nature and type of the relationship between watching televised animated cartoons and the information processing speed and Level for sample children in the age group [5-6] Years. The sample consisted of (225) boys and girls watching animation films at an average time of (6.8) and a standard deviation (1.9) in the age group of (5-6) years. The study adopted the descriptive approach and applied the tools to the study samples. The results were analyzed and compared. The study used a data collection form and a scale for measuring information processing speed and level. Methodology: In light of the study hypotheses, the descriptive approach was used. The tools were applied to the study samples and their results were analyzed and compared. Main Findings:The results of study gave rise to findings; the most important of which are that there are statistically significant differences between children with high watching and low watching in terms of the speed and the information processing level for those with high watching ... and there is a statistically significant effect of some of the factors of watching (televised animation – laptop animation - animated cartoons in both types) watching hours on weekends (less than four hours - more than four hours) on the speed and information processing level of the child. Applications of this study: This study can be applied to children in general and can benefit teachers and parents. Novelty/Originality of this study: The animated cartoons play a prominent role in developing the speed and information processing level, in light of the lack of excessive watching hours, particularly on public holidays, and the tendency to practice real activities in the environment. Also, there is a clear impact of animation films in light of watching hours on the speed and information processing level for children, as they provide them with a world full of scenes, beautiful nature, broad imagination and beloved symbols that make them guided by their content and seek to imitate them and process them in their understanding of reality, perception, and processing of the information they receive.

Abstract:

Traditionally, highway engineers use pencil and ruler to lay out lines and curves over contour maps for highway geometry design. Numerous calculations of stopping sight distance, minimum turning radius, and curve alignments are required during the design process to ensure safety, to minimize economic and environmental impact, and to reduce construction costs. Engineers usually perform iterative computations manually during the design process to meet design criteria and environmental constraints. The traditional process of highway geometry design is cumbersome and time consuming. The traditional approach limits engineers from taking a broader perspective in the overall highway geometry design process. Current method of three dimensional (3D) has nothing to do with highway design process. CARD/1 was developed to enhance the learning experience for highway engineers. This tool allows engineers to design the highway efficiently and to modify the design easily. A 3D highway geometry model can be generated by the software at final design to allow engineers to place themselves in the driver’s seat and maneuver through the designed highway at maximum design speed. Some key technologies of highway design with 3D-animaion based on CARD/1 was discussed in this paper.

Abstract:

This article focuses on a new amusement ride that blends several control systems by combining spinning-coaster thrills with interactive special effects. The Exterminator at Kennywood Amusement Park combines a ‘wild mouse’ coaster with the interactivity of a dark ride. ‘Dark ride’ is amusement maker parlance for fun house style frights that pop into view unexpectedly. A proximity sensor, positioned after the coaster and animation went in, begins the action sequence for this figure just as the riders come upon it. Bringing the Exterminator up to speed was a matter of controlling the coaster, controlling the animation, and controlling the interaction between the two independent systems. A process of trial and error, determining the right moment to start an event occurs only after the animation is in place and the carts are riding the rails. A double pneumatic fin brake below the track slows carts as needed before they enter the boiler.

Abstract:

Nature is full of geographical kinetic phenomena; some are tangible such as population emigration, money transfer, goods movement and transportation. Yet others are intangible such as energy, thoughts, reputation and civilization. These phenomena have got specific characteristics while moving such as the movement’s route, speed, locations, strength of the kinetic phenomena and their type and structure. Different geographical kinetic phenomena can be illustrated on maps called “Animation Maps”, which are considered part of the Thematic Maps, based on their nature and function by the motion symbols. This article studies most of the cartographic representation methods that are used in designing Thematic Maps. It also concentrates on motion symbolizing methods. It studies the nature and types of kinetic phenomena and identifies their different characteristics, and presents and analyzes its numerous demonstration ways on maps, using animation symbols. Finally, it reveals the best ways to design and present Animation Maps. This paper aims to study kinetic phenomena and their kinds and characteristics, and to analyze the methods currently used to demonstrate them on Animation Maps. This leads to suggest new methods and ways in this field, in order to assist in demonstrating geographical phenomena on maps accurately and clearly. The study reached a number of results such as determining cartographic representation methods and their fields, and finding the best optimal representation methods of kinetic geographical phenomena, and their different characteristics on Thematic Maps, and thus determining the best methods to design and present Animation Maps.

Abstract:

SummaryThe paper develops a simulation and animation environment for high-mobility rovers based on kinematic modeling. Various kinematic chains starting from the rover body to the wheels are analyzed and aggregated to obtain the model of the rover body motion in terms of the wheel motions. This model is then used to determine the actuations of the joints, wheels speed, and steering motors to achieve a desired motion of the rover over uneven terrain while avoiding loss of balance and tip-over. The simulation environment consists of a number of modules, including terrain and trajectory generation, and kinematic models for rover actuation and navigation. The animation of the rover motion over various terrains is developed, which allows observing the rover from various viewpoints and interacting with the system through a graphical user interface. The performance of the overall system is demonstrated by modeling a high-mobility space exploration rover, and the responses of the rover on uneven terrains are provided, which show the usefulness of the proposed modeling, simulation, and animation scheme.

Abstract:

This paper proposes a practical technique for fast animation of materials such as viscoelastic fluids. A fast animation of such materials is desperately desirable especially for real-time applications such as games. We compute the behavior of viscoelastic fluids approximately instead of the exact simulation by combining two well-established approaches, Smoothed- Particle Hydrodynamics and Shape Matching. This enables fast and stable computations. A combination is done by a simple linear interpolation of velocities. A variety of materials between a fluid and an elastic solid can be represented by changing only a parameter of linear interpolation. We also propose how to bring our approximate method closer to the actual motions of viscoelastic fluids including merging or splitting of objects. We demonstrate a high-speed performance of our method with presenting several interesting results.

Abstract:

The speed with which homes and other human edifices ‘return’ to a state of wilderness is a concern of McGahern's, expressed towards the end of Memoir, and this alignment of the passage of time and ecology will be the focus of this essay. Memoir is a work of memory and navigates the lieux de memoires of McGahern's formative years, as well as much of his adult life. The act of autobiographical remembrance is facilitated by a slowing down of time and slowness enables the percolation of memory through our consciousness, and therefore is, firstly, part of the mechanics of autobiographical authorship. In another way slowness is a tonal quality of McGahern's writing as he takes a Proustian meander through the physical and memorial lanes of his origins. Furthermore, the ecological animation of McGahern's narrative bespeaks a writer who is keenly sensitive to the virtues of ecological dwelling, as McGahern is alert to the interdependencies of human and non-human; he treats of the non-human as more than an inert backdrop to his narration; and his works not only lament the passing of a way of life, but they assert the currency of this decelerated lifestyle in the contemporary moment.

Abstract:

This research focus on the process of creating the world of “Balloon” through low poly visual style in 3D CG animation using an alternative non-photorealistic rendering method that is both efficient and visually astonishing. Low poly are chosen as a visual style because it represent the spirit of courage to explore the world outside the film’s story. By using low poly visual style in most of the environment, it creates a unique contrast between the environment and the character. The character is made using a traditional high poly modeling for 3D character. Through variety of experiments with various pipeline, the chosen method is considered the best to accommodate the filmmaker needs in both production time and the visual result. In order to determine the best technique, the research is conducted by testing the render results of some environment scenes within the film. The writer also experimented using procedural materials in the design of the world to help speed up rendering of the compositing process, in order to achieve good visual quality in a shorter production time. Keywords : low poly, non-photorealistic rendering, 3D CG animation

Abstract:

Mobile games and graphics are popular because un-tethered computing is convenient and ubiquitous entertainment is compelling. However, rendering graphics on mobile devices faces challenges due to limited system resources, such as battery energy, and low memory and disk space. Real time frame rates, low energy consumption and high image quality are all desirable attributes of interactive mobile graphics; however, achieving these objectives is conflicting. For instance, increasing mesh resolutions improves rendered image quality but consumes more battery energy. Therefore, the authors propose a mobile graphics heuristic to minimize energy consumption while maintaining acceptable image quality and interactive frame rates. Over the lifetime of a mobile graphics application, scene complexity, animation paths, user interactivity and other elements all change its CPU and resource demands. In this regard, a heuristic that dynamically changes scene mesh LoDs and amount of CPU timeslices allotted to the mobile graphics application is presented to select optimal operating conditions that balance rendering speed, energy conservation and image quality. Additionally, a workload predict model is proposed so that the heuristic can monitor both application workload and the availability of resources of mobile devices periodically, while adaptively determining how much resources will be allocated to applications.

Abstract:

Aiming at the face photos of film and television animation, this paper proposes a new fast three-dimensional (3D) face modelling algorithm. First of all, based on the LBF algorithm, this paper proposes a multifeature selection idea to automatically detect multiple features of the face. Secondly, in order to solve the shortcomings of slow training speed while achieving large pose face alignment, the regression-based CNN is selected as the algorithm to achieve fast convergence. Then, due to the influence of various factors, the extracted feature points are not completely correct, and Gabor features are used to screen the matching of feature points. Finally, by analysing the principle of 3DMM 3D face reconstruction, a single-view 3D face reconstruction method based on CNN is proposed. The experimental results show that the algorithm in this paper has good reconstruction performance and real-time performance and can realize the rapid modelling of human face.

Abstract:

The use of multifocal-plane, time-lapse recordings of living specimens has allowed investigators to visualize dynamic events both within ensembles of cells and individual cells. Recordings of such four-dimensional (4D) data from digital optical sectioning microscopy produce very large data sets. We describe a wavelet-based data compression algorithm that capitalizes on the inherent redunancies within multidimensional data to achieve higher compression levels than can be obtained from single images. The algorithm will permit remote users to roam through large 4D data sets using communication channels of modest bandwidth at high speed. This will allow animation to be used as a powerful aid to visualizing dynamic changes in three-dimensional structures.

Abstract:

The spatial conflicts in the construction of high-speed railways not only reduce project efficiency, but also lead to serious accidents. To address these key issues, this paper presents a dynamic simulation method for constructions processes based on a virtual geographic environment. This approach can facilitate the identification of conflicts in the construction scheme through accurately expressing and analysing the intricate spatio-temporal relations among railway facility components, construction equipment and the surrounding environment. First, a high-precision virtual geographic scene in which the construction process and methods can be visualized and modelled intuitively is established with terrain, imagery, and engineering 3D models. Then, the overall construction processes can be accurately simulated by a sequential display of the railway components and the behaviour of construction equipment. To simulate the behaviour of construction equipment, the linkage relations between each joint of construction machinery are accurately modelled and animation control parameters are extracted. Finally, a construction simulation of a high-speed railway bridge was performed, and the experimental results show that the proposed method can provide a scientific basis for the optimization of complex engineering construction schemes, safety hazard assessments, and related full life cycle tasks.

Abstract:

The recovery of 3D information of a face from two (or more) images has been extensively studied and many interesting applications have been implemented. This paper proposes a model-based 3D face pose and animation tracker with auto-registration using a binocular EKF kernel for real time application like human computer interface. Compared with previous trackers, this tracker is able to automatically register face model, which eliminates the traditional manual registration process. Another major contribution is to use augmented measurement as a regularization strategy for suppressing variables coupling and over-fitting problem. This work also gives a compact factorized mathematic representation of the tracking kernel, which is easier to implement. Both synthetic and real experimental results show significant advantages of the proposed tracker from the aspects of processing speed and reliability compared with the conventional monocular tracker and Levenberg–Marquardt tracker.

Abstract:

In the past fifteen years avant-garde architectural practice has been developing in the field of parametric design at the phenomenal speed. This success can be attributed to the development of advanced computer software, previously used for animation and rendering. The parametric design method uses advanced computer scripts which transforms mathematic algorithms of relations between parameters into creations of complex geometries, which were almost impossible to produce and even imagine without it.Question remains will these mathematical equations inputed thru scripting language as algorithms will add additional value to the design, or traditional, intuitive way of designing still can be relevant enough in 21st century. There are doubts that without deep intellectual background parametric design process can play for the play’s sake with the shapes of objects, buildings and urban structures.

Abstract:

Abstract Most studies on verticality’s embodiment showed that up positions were related to positive emotions whereas down positions were related to negative ones (Meier & Robinson, 2004). Research on motion perception found that a parabolic motion both induced animation attribution (Tremoulet & Feldman, 2000) and implied negative feelings (Chafi, Schiaratura, & Rusinek, 2012; Podevin, 2009; Podevin, Chafi, Rusinek, & Békaert, 2012). We hypothesized that seeing a parabolic downward motion will increase both the memorization for words and the execution’s speed of a serial subtraction compared to a parabolic upward motion. Results showed that the downward motion had enhancing effects both on the serial subtraction and on the number of recalled words, independently of their valence. These findings are interpreted as marking processes related to an adaptive behavior in response to a negative stimulus.

Leaves falling gently or fluttering are common phenomenon in nature scenes. The authenticity of leaves falling plays an important part in the dynamic modeling of natural scenes. The leaves falling model has a widely applications in the field of animation and virtual reality. We propose a novel modeling method of fluttering leaves based on point cloud in this paper. According to the shape, the weight of leaves and the wind speed, three basic trajectories of leaves falling are defined, which are the rotation falling, the roll falling and the screw roll falling. At the same time, a parallel algorithm based on OpenMP is implemented to satisfy the needs of real-time in practical applications. Experimental results demonstrate that the proposed method is amenable to the incorporation of a variety of desirable effects.

Abstract:

Purpose The purpose of this paper is to achieve the acceleration of 3D object transformation using parallel techniques such as multi-core central processing unit (MC CPU) or graphic processing unit (GPU) or even both. Generating 3D animation scenes in computer graphics requires applying a 3D transformation on the vertices of the objects. These transformations consume most of the execution time. Hence, for high-speed graphic systems, acceleration of vertex transform is very much sought for because it requires many matrix operations (need) to be performed in a real time, so the execution time is essential for such processing. Design/methodology/approach In this paper, the acceleration of 3D object transformation is achieved using parallel techniques such as MC CPU or GPU or even both. Multiple geometric transformations are concatenated together at a time in any order in an interactive manner. Findings The performance results are presented for a number of 3D objects with paralleled implementations of the affine transform on the NVIDIA GPU series. The maximum execution time was about 0.508 s to transform 100 million vertices using LabVIEW and 0.096 s using Visual Studio. Other results also showed the significant speed-up compared to CPU, MC CPU and other previous work computations for the same object complexity. Originality/value The high-speed execution of 3D models is essential in many applications such as medical imaging, 3D games and robotics.
