D 3 . 5 Integration in Virtual Environments

In this report we describe how some the interaction models and information services from the PuppyIR Framework could be integrated into Virtual Environments that are geared towards use in the context of cultural objects and/or younger audiences. PuppyIR D3.5 Integration in Virtual Environments

3-D Virtual Worlds: Education and Learning

3-D virtual worlds are increasing in popularity as a medium for higher education. In this research, we assess the efficacy of two instruction strategies in a virtual world environment, Second Life, and their effects on interactivity, social presence, and perceived learning. The two instruction strategies are direct and interactive instruction strategies. Our findings suggest that the interactiv...

Virtual Drilling - Sculpturing in 3-d Volumes

| In this paper we propose a virtual drilling sculpturing algorithm applied on 3-D objects. The 3-D objects can either be simple geometrical shapes such as cubes and spheres or more complicated objects as teeth. In the second case, we consider that we are provided with a sparse set of parallel and equi-distant slices of the 3-D object. With that set of slices we reconstruct the 3-D object using...

Elasticity: Stress and strain: BASIC SEISMOLOGY 3

E lasticity is the property that enables a fluid or solid body to resist change in size and shape when an external force is applied and to return to its original size and shape when the force is removed. This concept is a major building block in seismology because it is the elastic properties of rocks which allow seismic waves to propagate through the earth. The theory of elasticity is one of t...
