TeraGrid is a national-scale computational science facility supported through a partnership among thirteen institutions, with funding from the US National Science Foundation [1]. Initially created through a Major Research Equipment Facilities Construction (MREFC [2]) award in 2001, the TeraGrid facility began providing production computing, storage,(More)
Research in the area of spatial visualization enjoys a long tradition in the discipline of cognitive psychology. However, the computer graphics profession, particularly the educational component, takes into account a person's spatial abilities as a means for designing effective instructional experiences and assessments. It builds on a learner's visual or(More)
One element of using contemporary computer graphics tools is the creation of accurate 3D geometry for a variety of purposes. As part of developing effective instructional experiences for students engaged in such activities, computer graphics educators must take into account a person's spatial abilities and skills. Literature has shown these abilities are(More)
The emergence of computer graphics as a powerful medium to communicate information is one of the primary reasons graphics is playing a larger role in engineering, science, and technology. Such a powerful medium has emerged from many sources. The author suggests that there is a philosophical foundation and a unique body of knowledge necessary for a(More)
We present a novel approach for a virtual granular material interactive manipulation with force feedback. A user can interactively change a height-field model of sand by dragging objects inside. The virtual sand behaves like real sand moving to the sides and falling back, filling holes and irregularities on the surface. The dragging object position is(More)
We report an initial study on the use of visuohaptic simulation in teaching STEM (Science, Technology, Engineering and Mathematics) topics, with particular emphasis on physics concepts related to the learning of nanotechnology at the undergraduate level. Visuohaptic simulations of point charges and their interactions were developed. Thirty-eight(More)
This is to certify that the thesis/dissertation prepared By Entitled For the degree of Is approved by the final examining committee: Chair To the best of my knowledge and as understood by the student in the Research Integrity and Copyright Disclaimer (Graduate School Form 20), this thesis/dissertation adheres to the provisions of Purdue University's "(More)
The present study investigated the use of visual trajectory and haptic force information in learning concepts involving force. Specifically, learning modules for instructing buoyant forces were developed for use with a computer monitor and a force feedback device. Students from an elementary school at the fourth and sixth grades were recruited to(More)
