Project Title: Designing Form and Structure with Web3D Simulation

Research Team: Nicholas Polys Ph.D., Felipe Bacim, MehdiSetareh Ph.D., Brett Jones Ph.D.

Thrust Area: Visualization and Virtual Prototyping, Engineering Education

Problem Statement

Related Work

There is a significant difference between tools used for the design of form and those that evaluate the structural properties of the form. We have integrated these into a usabledesigntool for students and practitioners to better understand the inter-relationships between

structure and form

Usability Engineering eLearning Systems-

A paradox: the domain expert is not the end user!

Bacim, F., Polys, N., Setareh, M., Chen, J., Li, J., & Ma, L. (2010). Cognitive Scaffolding in Web3D Learning Systems: A Case Study for Form and Structure. Paper presented at the Proceedings of the 15th International Conference on 3D Web Technology. ACM SIGGRAPH.

Approach and Methods

How Ours is Different

  • An Architecture, Education and CS collaboration to develop and evaluate simulation tools for design education
  • Interactive 3D design client, web simulation and management services
  • Website with extensive text, image, video and 3D resources on space frame structures is linked from the Help menu
  • Run a series of studies on the information and interaction design of the client tool interface; specifically scientific visualization and direct manipulation morphing
  • Run a series of studies with the tool in undergraduate classes

Key investment requirements for long-term impact of interactive 3D content includes: portability, interoperability and durability. Extensible 3D (X3D) is an open, royalty-free standard developed through the Web3D Consortium and ratified through the International Standards Organization (ISO). Our tool is based on the open-source Xj3D rendering library and provides designers web access to their runs on a structural simulation server.

Project Plan (Tasks and Timeline)

Iterative development and evaluation of the tool functionality, interface, and integration with courseware

http://legacy.caus.vt.edu/setareh/archresearch

  • Evaluations
  • Formative:
    • Scientific visualization of structural networks
    • Deforming interactions in design
    • Undergrad Architecture Studio (Spring 2011 Virginia Tech)
  • Summative:
    • Undergrad Architecture Studio: Virginia Tech, U Illinois
    • Urbana-Champlain, Hampton University (Fall 2011)

Deliverables and Benefits

  • SAFAS Designer: 3D space frame designer with several interactive deformers and coupled to structural simulator (SAP v4 and SAP 2000) through the web
  • Multimedia structures website (Dublin-core) with information, images, videos, and 3D
  • Experimental data on principles for the visual perception of variables such as tensile force, stress, and load on structural members
