3D Scanning & Modeling Consultation Notes

Thanks to Wasfi for taking notes during our 3D-scanning introductory meeting. I’ve expanded a couple things and added some more resources that I’m aware of.

• Main people involved
  • From SIF
    • Nathan Sharratt <nsharratt1@gsu.edu>
    • Joe Hurley <jhurley@gsu.edu>
    • Brennan Collins <brennan@gsu.edu>
  • Other Contacts
    • Bryan Sinclair <bsinclair@gsu.edu>
    • Robin Wharton <robin.s.wharton@gmail.com>

• Resources Available at CURVE and CII (Center for Instructional Innovation)
  • Multiple Software Options
  • All software options are available for free by the university. Licenses might be required for individual use made through here
    • PIX4D (more for landscapes)
    • Agisoft Photoscan (in between large and small – uses photos)
    • Memento (more for individual models)

• Hardware at GSU (available in the library and CURVE; linked to relevant sites)
  • Laser Scanners inside CURVE
  • FARO Scanner
  • Regular cameras on smartphones or DSLRs work too (DSLRs offered by the Library, Digital Aquarium, and CII)
  • 3D tools at Sculpture – Area Coordinator Mike Wsol <mwsol@gsu.edu>
    • CNC Shopbot Router
    • CNC Plasma Cutter
    • Laser Cutter
    • 3D Scanner

• 3D scanning problems and solutions
  • Limitations
    • Artifacts in scans
    • Web embedded scan result in loss of resolution
    • Issues with rendering time
    • Some scanners restrict sizes of objects (CURVE laser scanners can only take up to certain size objects)
  • Alleviations
    • Scanning with certain methods will help alleviate artifacts
    • High quality connections or just using the software used to make it for scanning will help with resolution.
    • Using high-end computers available through the university will help with rendering times
    • Use a camera (no restrictions but less accurate) or another scanner

• Scholarship and Research Grants
  • Scholarship
    • Victoria, Canada classes
  • Monetary
    • Creative Media Industries grant
    • Tech Fee
    • Grants through University Research (includes the National Institute of Health and the National Science Foundation)

• Example Projects
  • atlantaartifacts.net
  • brainbrowser
  • Databases of 3D scans with medical data available for free
    • National Institute of Health Exchange
  • General databases of 3D models
    • Memento

• Other links to explore
  • Tutorial on direct medical data to 3D models
  • 3D techniques and tutorials
  • Good list of what you can do with 3D scanning and its limitations
