Visualization and Animation in Engineering Science and Mechanics

This project explores the use of virtual environments and the CAVE technology in collaborative research and distance learning in the field of engineering science and mechanics. It also showcases the capabilities of the U.V.A.G DIVERSE system, a device-independent virtual environment that is reconfigurable, scalable, and extensible. The project covers topics such as crane-ship simulation, building structure visualization, molecular docking, and cardiovascular flow analysis.

  6. DIVERSE: current and future features • Current SGI-Performer API: DIVERSE interface to Performer (DPF) • Works out of the box in SGI-Irix and Linux • Elegant Interface • Designed for rapid application development, Examples: • 1. Loading a model and navigating (“fly-thru”) takes only 11 lines of code • 2. A computer science student with no experience in VR development was able • to build a prototype visualization tools for nanostructures in 4 days • Dynamic Shared Objects (DSOs) load or unload during execution • Generic IO support (wands, mice, keyboards, trackers, etc.) • Write once -- run everywhere with no changes • Powerful shared memory architecture • Robust augmentation to performer • Generic collaborative tools • Future release August 2003: • Backward compatible • Push or Pull IO interface • XML based configuration • OS 10 support (via X11) • Native MS-Windows support • Cross platform architecture • Windowing API independent • Display independent OpenGL Support • Open SceneGraph augmentation • Message passing abstraction

  10. ASPIRES: Combining visualization with haptic feedback to enhance molecular docking 6-DOF with force haptic feedback along x-y-z Haptic device on the right is linked to the molecule (boundary highlighted) above where the researcher/student can feel the force / atomic potentials associated with docking the molecule onto the large protein structure.

  16. Space Systems Simulation Lab (SSSL)/UVAG Undergraduate Research -- Michael Shoemaker -- 4/18/03 • Goal: Explore alternative ways of controlling spacecraft simulators from within a virtual environment. • Motivation: (So what’s the point?) • Combine usefulness of both systems to achieve new results and compensate for deficiencies in the individual systems. • Current Focus: Manual control, with emphasis on docking procedures. • Implementation: • (1). Orbital environment • – astrodynamics • (2). Spacecraft simulator • – attitude dynamics and control • Other Possible Applications: • Supervisory control • Planning • Observation • SSSL Web Page: http://www.aoe.vt.edu/research/groups/sssl/ • Presentation: http://www.jwave.vt.edu/~rkriz/Presentations/AOE4994_DTK-DPF_ShoemakerPrj/ • Project Contact: Mike Shoemaker, mshoemak@vt.edu, http://www.aoe.vt.edu/research/groups/sssl/mshoemaker/ SSL CAVE Actual spacecraft simulator In the SSSL Laboratory Computer graphics representation of spacecraft simulator U V A G
