We describe a project to create a three-dimensional digital model of Michelangelo’s Florentine Pietà. The model is being used in a comprehensive art-historical study of this sculpture that includes a consideration of historical records and artistic significance as well as scientific data. A combined multi-view and photometric system is used to capture hundreds of small meshes on the surface, ea...

This paper describes initial work carried out to advance the use of vision metrology and three dimensional visualization techniques in structural testing and monitoring. A description is given of a methodology for semi-automatically generating dynamic three dimensional computer graphics models, which is employed to provide a three dimensional spatial framework for conventional engineering instr...

This paper presents a model of a virtual laboratory for an introductory computer science course. The proposed model aims at solving a number of problems involved in the educational procedure of such a course. The model architecture consists of seven modules, each one corresponds to a specific topic of the course. Every module provides several different services in order to assist students to as...

This paper describes three varieties of realism that need to be considered in evaluating computer graphics images and defines the criteria that need to be met if each kind of realism is to be achieved. The paper introduces a conceptual framework for thinking about realism in images, and describes a set of research tools for measuring image realism and assessing its value in graphics applications.

Visibility computation is one of the fundamental problems in 3D computer graphics, and due to ever-increasing data-sets its relevance is likely to increase. One of the harder problems in visibility is occlusion culling, the process of removing objects that are hidden by other objects from the viewpoint. This paper gives an overview of occlusion culling algorithms and the data structures they op...

This paper explores the use of multi-instance enrollment as a means to improve the performance of 3D face recognition. Experiments are performed using the ND-2006 3D face data set which contains 13,450 scans of 888 subjects. This is the largest 3D face data set currently available and contains a substantial amount of varied facial expression. Results indicate that the multi-instance enrollment ...

We propose a vector representation (called a 3D signature) for 3D face shape in biometrics applications. Elements of the vector correspond to fixed surface points in a face-centered coordinate system. Since the elements are registered to the face, comparisons of vectors to produce match scores can be performed without a probe to gallery alignment step such as an invocation of the iterated close...
