Ever since the development of Computer Graphics in the industrial and academic worlds in the seventies, public knowledge and expertise have grown in a tremendous way, notably because of the increasing fascination for Computer Animation. This specific field ...
In combination with the rapid technical improvements of computers, building large virtual scenes has become a popular field in computer graphics for education, films or games. Often, virtual humans populate scenes such as real reconstructed city, disappear ...
Facial expression recognition is a hard and ambiguous problem in computer vision. It is hard due to the wide variety of faces and the wide variety of ways of representing the same expression. And it is ambiguous because, even though common approaches treat ...
The paper proposes virtual input devices based on collision detection for easy construction of interactive 3D graphics applications which use a motion capture system as a real time input device. Each virtual input device is composed from several collision ...
This thesis presents how to visualize a large crowd of virtual human characters in real time on a standard issue personal computer. The virtual humans are distributed into rendering fidelities such that the humans closer to the viewer are detailed and expr ...
We present a method for modeling and animating a wide spectrum of volumetric objects, with material properties anywhere in the range from stiff elastic to highly plastic. Both the volume and the surface representation are point based, which allows arbitrar ...
In this paper, we extend our previous work (Proc. Computer Animation and Simulation, pp. 125-135, Aug. 2000) and propose a muscle model that is suitable for computer graphics based on physiological and anatomical considerations. Muscle motion and deformati ...
We have developed a learning platform to simplify and improve teaching and practice of computer graphics for beginners and advanced students. Our goal is to offer a set of tools to help students having a better mental vision of the abstract notions introdu ...
Migrating computer graphics to the Web poses several problems, but with new standards and technology advances, graphics applications can balance latency and bandwidth constraints with image quality. The paper discusses Web graphics standards, distributed v ...
Computer Graphics came into the medical world especially after the arrival of 3D medical imaging. Computer Graphics techniques are already integrated in the diagnosis procedure by means of the visual tridimensional analysis of computer tomography, magnetic ...
