AnimDiff: Comparing 3D Animations for Revision Control

The process of animating a complex 3D character can be a time consuming activity which may take several iterations and several artists working in collaboration, each iteration improving some elements of the animation but potentially introducing artifacts in others. At present there exists no formal process to collate these various revisions in a manner that allows for close examination of their differences, which would help speed up the creation of 3D animations. To address this we present a method for equivalence checking and displaying differences between differing versions of an animated 3D model. Implemented in a tool that allows selective blending of animations, this provides a first step towards a 3D animation revision control system

Fair Ranking System

Ranking greatly assists us in decision making by allowing us to consider numerous options, with a variety of attributes and turn it into an understandable model. Yet, accurate rankings can be difficult for one to construct without extensive and proper knowledge on what you’re ranking. Thus arose the need for fair ranking systems that effectively elicit data from users and produce accurate rankings that satisfy and serve the users’ needs. In the pursuit of creating a fair ranking system this team proposes Rankit_Experimenter, a user study that tests the merits of three preference collection methods. Results indicate that categorical binning is the best value model: providing a substantial amount of data for the underlying ranking algorithm, while requiring minimal effort from the user

A Flexible Framework for Collaborative Visualization Applications Using Java Spaces

The complexity of modern tasks is rising along with the level of technology. Two techniques commonly used to deal with complexity are collaboration and information visualization. Recently, computer networks have arisen as a powerful means of collaboration, and many new technologies are being developed to better utilize them. Among the newer, more promising of these technologies is Sun Microsystems\u27 JavaSpaces ™, a high-level network programming API. This thesis describes a tool for developing collaborative visualization software using JavaSpaces-an application framework and accompanying toolkit. In addition to a detailed description of the framework, the thesis also describes an application implemented using the framework, discusses the benefits of development under the framework, evaluates the performance of JavaSpaces in the context of the framework, and addresses the issue of network bandwidth limitations, which are a concern when developing visualizations that deal with large data sets

JuxtaLearn D3.2 Performance Framework

This deliverable, D3.2, for Work Package 3 incorporating the pedagogy from WP2 and orchestration factors mapped in D3.1 reviews aspects of performance in the context of participative video making. It reviews literature on curiosity and engagement characteristics of interaction mechanisms for public displays and anticipates requirements for social network analysis of relevant public videos from WP6 task 6.3. Thus, to support JuxtaLearn performance it proposes a reflective performance framework that encompasses the material environment and objects required, the participants, and the knowledge needed
