“…Velocity, bending, stretching of mass-spring systems play a key role in motion of this deformation. Hyun (33) proposed a sweep surface instead of skeleton. The sweep surface can afford to realize anatomical details such as bone-protrusion, muscle bulge, skin folding.…”

Virtual Reality makes a virtual environment more realistic and, furthermore, it provides a variety of experiences which we cannot have in reality. A drastic growth of GPU performance and increase of computing capability make virtual environment more realistic than ever. One important element of constructing virtual environment is to animate 3D characters. Many researchers have been studying 3D characters animating and a myriad of methods have been proposed to make them more realistic. In this paper, we discuss the technologies and characteristics of 3D character animation. We believe that realistic characters in Virtual Reality will be applied to various fields: education, film and game industry, business and, particularly, medical area such as telemedicine, virtual surgery, etc.Key WordsZZ3D character animation ㆍBlend shape ㆍSkinning.

“…Another approach was a physical deformation which consisted of a mass and spring system, derived from mechanical laws of particles (Vassilev and Spanlang, 2002). Although this approach was less computationally demanding than the anatomical approach, it was still considered to be less suitable for real time application and was mainly for off-line simulation and animation (Hyun et al, 2005). However, the geometric approach was the cheapest in terms of computational need and hence was widely used for various applications e.g.…”

“…The drawbacks of this approach is the more examples poses, the more complex the motion representation would be. Shen and Thalmann (1996) and Hyun et al (2005) proposed a different approach i.e. the sweep based approach, which was characterized by the usage of cross sections to reconstruct and express the deformation.…”

“…the sweep based approach, which was characterized by the usage of cross sections to reconstruct and express the deformation. Hyun et al (2005) adopted this approach by using ellipses which fit tightly to the cross section and sweep them along the link between the joints. These ellipses were then used to govern the deformation by changing its orientation, accordingly to the joint angle changes.…”

Abstract. The human model for ergonomic simulation has improved in terms of its reliability and appearance and yet there seems to be less attention paid to create a realistic and accurate flesh deformation around the joint. This study, a part of ongoing research, proposes a combination of manual and automatic (3D body scanner) measurements to create a database for flesh deformation prediction i.e. flesh deformation area and cross section changes, around the elbow joint. The database consists of two race groups i.e., Caucasian and Asian (23 subjects, 11 males and 12 females), which were carefully chosen to represent a variety of height and body type. The prediction results for both flesh deformation area and cross section changes are discussed as well as their relevance for the next stage of the study.

“…In some recent studies [1]- [3], sweeping has been interpreted from a slightly different point of view. Instead of being used as a modeling tool for generating new objects, sweeps have been employed as control mechanisms for the modification of existing shapes.…”
