    Most existing visualization tools utilize only the visual channel to represent information. Several studies have demonstrated that sonification, the use of sound as an alternative or additional channel for data representation, can help increase the dimensionality of the visual representation and aid in the interpretation of information. We introduce a new sonification module for a visual data expl... View full abstract»

    This paper proposes a toon shading technique that can depict morphological features of an object precisely. We have applied two algorithms to conventional toon shading technique. The first is to express the shape of important areas by increasing and decreasing local contrast proportional to the degree of visual importance of an area by using virtual local lights while maintaining cartoon effect. T... View full abstract»

    The arrangement of atoms at the surface of a solid accounts for many of its properties: hardness, chemical activity, corrosion, etc. are dictated by the precise surface structure. Hence, finding it, has a broad range of technical and industrial applications. The ability to solve this problem opens the possibility of designing by computer materials with properties tailored to specific applications.... View full abstract»

  • Considerations for Believable Emotional Facial Expression Animation

    Publication Year: 2009 , Page(s): 61 - 66
    Cited by:  Papers (2)
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (909 KB) |  | HTML iconHTML  

    Facial expressions can be used to communicate emotional states through the use of universal signifiers within key regions of the face. Psychology research has identified what these signifiers are and how different combinations and variations can be interpreted. Research into expressions has informed animation practice, but as yet very little is known about the movement within and between emotional... View full abstract»

  • Creating Realistic Human Motions with PBSO

    Publication Year: 2009 , Page(s): 67 - 71
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (300 KB)  

    It is a difficult task to create a realistic human animation because of the high complexity of human motion. To address this problem, a new method is presented for producing physically valid motion with example motions. The core of our method is physics-based space-time optimization (PBSO). PBSO introduces physical constraints into conventional space-time optimization and then ensure the physical ... View full abstract»

    This paper reports a study that aimed to determine whether character geometric model (i.e. segmented vs. seamless) has an effect on how animated signing is perceived by viewers. Additionally, the study investigated whether the geometric model affects perception at varying degrees of linguistic complexity-specifically handshape complexity. We modeled and animated two polygonal 3D characters: Torren... View full abstract»

    Fluid simulation, proposed here, runs on an unrestricted octree data structure which uses mesh refinement techniques to enable higher level of detail and solves Navier Stokes equations for multiple fluids. We also show our solution for floating objects and unmoving obstacles by setting up the boundary conditions and solving the velocity of objects using a simple rigid body solver. We propose techn...
