Ye' Ole' Agenda

  • Web
  • Hot Stuff (fire science)
  • You're Magnetic (simulation)
  • Math Functions in VR

Web

  • It's still the web, stupid
  • Distribution
  • My kingdom for an URL

and you think your demo is hot!

360 degree fire

Crown Fire

Interacting with 360 Video

  • Authoring
  • Data display
  • Interaction

Making Burn Interactive

  • Toolchain
  • VR Hardware (Oculus Rift)
  • Software WebVR/XR - a-frame
    • WEB WEB WEB
  • Development also via glitch

​​(shockingly is not a toy!)

Making Burn Interactive (2)

  • Tasks
  • Data Wrangling
  • Prototype data display
  • Synchronize data and video
    • video "currentTime" is main magic
  • ​Set up locations of temperature sensors in video (by hand using specialized tool)
  • Link locations with data (also by hand coding)
  • Added video zoom and rotation capabilities..primary user will be on desktop
  • Mouse for desktop / Controllers for VR

MAGNETS

BITCHES

It's Magnetic

The Object Oriented MicroMagnetic Framework (OOMMF) project at ITL/NIST -  Mike Donahue, and Don Porter.

Visual Analysis of Micromagnetic Reversal

Magnetic simulation with RIFT output

Paraview with RIFT in use

Justin Kauffman

Use immersive visualization to understand and characterize the dynamics of magnetization reversal in micromagnetic devices.

New (for us) workflow

  • Paraview modeling
  • Export data
    • still missing semantics for "arrows"
  • view via WebVR or Paraview VR

Digital Library of Mathematical Functions

in VR

Last Year's DLMF VR

New DLMF VR

Moving towards integration with DLMF web site

Gallery of Functions -> public access to multiple file formats

Towards DLMF Integration

  • Standalone surface functionality in VR

Justin Slud (developer)

DLMF Gallery

  • Multiple file formats
  • Ability to use surfaces as graphic assets
  • Public domain with source attribution

Prototype DLMF Gallery

Speaking of Multiple Formats -> STL

Conclusions

WebXR for the win
