We investigate architechural schemes, generalizing that of existing graphics engines, supporting fast rendering of traingle meshes. A mesh defined on <italic>n</italic> vertices is rendered by sending vertices down a graphics pipeline, after which they are pushed on a stack to by popped when no longer needed. Only individual traingles whose vertices are(More)
Parameterization of 3D mesh data is important for many graphics applications, in particular for texture mapping, remeshing and morphing. Closed manifold genus-0 meshes are topologically equivalent to a sphere, hence this is the natural parameter domain for them. Parameterizing a triangle mesh onto the sphere means assigning a 3D position on the unit sphere(More)
We present a new technique for passive and markerless facial performance capture based on <i>anchor frames</i>. Our method starts with high resolution per-frame geometry acquisition using state-of-the-art stereo reconstruction, and proceeds to establish a single triangle mesh that is propagated through the entire performance. Leveraging the fact that facial(More)
Sensor network applications frequently require that the sensors know their physical locations in some global coordinate system. This is usually achieved by equipping each sensor with a location measurement device, such as GPS. However, low-end systems or indoor systems, which cannot use GPS, must locate themselves based only on crude information available(More)
