“…6. Note that the Photoscan software performed the assignment process of a colour value in 2D to a 3D geometry using UV-mapping procedure [32]. In a texture map, u and v coordinates in 2D space are basically connected to 3D (x, y and z) coordinates.…”

This paper presents an Unmanned Aerial Vehicles (UAV) based 3D city modelling approach to be used in managing and planning urban areas. While the urban growth is rapidly increasing in many places of the world, the conventional techniques do not respond to the changing environment simultaneously. For effective planning, high-resolution remote sensing is a tool for the production of 3D digital city models. In this study, it is aimed at designing the remote sensing by UAV through urban terrain. Using all the information produced from UAV imagery, high-accurate 3D city models are obtained. The analysis of XYZ data of the derived from 3D model using UAV photogrammetry revealed similar products as the terrestrial surveys which are commonly used for the last development plans and city maps. The experimental results show the effectiveness of the UAV-based 3D city modelling. The assessed accuracy of the UAV photogrammetry proved that urban planners can use it as the main tool of data collection for boundary mapping, changes monitoring and topographical surveying instead of GPS/GNSS surveying.

“…More and more video games, such as L.A. Noire, The Last of Us, or Assassin's Creed: Unity, and virtual environment applications aim for the highest possible realism of their characters and worlds. 28 However, we are not aware of research on the impact of motion realism in video games. But the influence of motion realism in animated clips and movies has been explored.…”

Real‐time animation controllers are fundamental for animating characters in response to player input in digital games. However, the design of such controllers requires making trade‐offs between the naturalness of the character's motions and the promptness of the character's response. In this paper, we investigate the effects of such trade‐offs on the players' enjoyment, control, satisfaction, and opinion of the character in a simple platform game. In our first experiment, we compare three controllers having the same responsiveness, but varying levels of naturalness. In the second experiment, we compare three controllers having increasing realism at the expense of responsiveness. In our third experiment, we keep motion naturalness and responsiveness constant but vary the avatar. Not surprisingly, our least responsive controller negatively affects players' performance and perceived ability to control the character. However, we also find that players are most satisfied with their own performance using our least natural controller, that differences in animation can significantly alter players' enjoyment with responsiveness being equal, that players do not report increased motion quality with our most natural controller, although viewers outside of the game context do, and that the avatar model affected the perception of the character but not players' enjoyment or perceived realism.

“…The adoption of virtual characters generally has two main functions: first, the virtual characters can draw huge attractions from the audience and bring a public recognizing to the museum; second, the virtual characters can make the visitor gain authentic experience about the situations which might not be existed any more [3]. Virtual characters can play important role in virtual systems because it can enhance communication efficiency via manners of interpersonal communication by well representing the information as well as improving the general publicity [4,5]. Pan examines the categories of virtual characters by studying the story genres and identifying the potential resources for creating new virtual characters: the traditional and contemporary cultural resources [6].…”

Shanghai Expo 2010 is an international event which will demonstrate the scientific, economic and cultural advance of the exhibiting countries. The local government launches a project named on-line Shanghai Expo in order to make the event accessible to people through Internet. Virtual reality technologies, especial intelligent virtual environment (IVE), are exploited to support the Expo. IVE, based on semantic, is the integration of Virtual Environment and Artificial Intelligence. It can improve the interaction between avatar and the virtual world by giving the objects in the environment semantic information. In this paper we employ intelligent virtual environment to build a virtual environment of realistic behavior and intelligent navigation.
