Space-Time Prism Model

DEFINITION During the last decade, the proliferation of location-aware devices, such as GPS and smartphones, has given rise to the collection of huge amounts of moving object data in the form of finite sequences of time-stamped geographical locations. These sequences of space-time points encode (a sample of) the trajectories of moving objects. The location of the moving objects is unknown betwe...

Prism Geometry: Simple and Efficient 3-D Spatial Model

With the recent increase of demands for 3D information, we need a robust data model of 3D spatial objects to meet the requirements from diverse applications. For this reason, several studies have been done out by ISO/TC211 and OGC, among which the data model of ISO 19107[2] and the data model for KML[6] are the most important ones. The data model of ISO 19107 provides a strong expressive power ...

An Efficient Volumetric Method for Building Closed Triangular Meshes from 3-D Image and Point Data

We present a volumetric method that can e ciently create triangular meshes from 3-D geometric data. This data can be presented in the form of images, pro les or unordered points. The mesh model can be created at di erent resolutions and can also be closed to make a true volumetric model.

Post - Rendering 3 D Image Warping : Visibility ,

William R. Mark POST-RENDERING 3D IMAGE WARPING: VISIBILITY, RECONSTRUCTION, AND PERFORMANCE FOR DEPTH-IMAGE WARPING (Under the direction of Dr. Gary Bishop) The images generated by real-time 3D graphics systems exhibit enormous frame-to-frame coherence, which is not exploited by the conventional graphics pipeline. I exploit this coherence by decoupling image rendering from image display. My sy...
