A Framework for the Acquisition, Processing and Interactive Display of High Quality 3D Models


Organizer: H.-P. Seidel, MPI Informatik

High quality 3D models are quickly emerging as a new multimedia data type with applications in such diverse areas as e-commerce, online encyclopaedias, or virtual museums, to name just a few. This tutorial presents new algorithms and techniques, developed by the speakers and others, for the acquisition and real-time interaction with virtual 3D objects. These algorithms and techniques are presented in a complete framework for the acquisition, processing, and interactive display of high quality 3D models.

Realistic appearance of 3D models necessitates the modeling of physical properties of an object. An object's reflectance behavior is crucial for photorealistic rendering quality and requires the measurement of accurate material properties. Recent work on the image-based reconstruction of spatially varying BRDFs enables the generation of high quality models of real objects from a sparse set of input data. This together with advanced interactive rendering techniques realistically reproduces the appearance of the original object under arbitrary viewing and lighting conditions. Beyond changes to viewing and lighting conditions, a wider class of interactions with virtual 3D object is desirable. Modeling of an object's interaction behavior requires the measurement of physical properties which govern this behavior. This tutorial will briefly introduce the University of British Columbia active measurement facility (ACME), a novel type of scanner of object interaction behavior. In particular, the scanning of the deformation behavior of soft objects is discussed in detail.
