This is my interactive HTML5 augmented reality (AR) flood simulation project for Iowa Flood Center.

The main aims of this project:

  • Augmented reality for the Web: stream webcam video to a web browser, track encoded marker images and overlay 3D models on top of them
  • Terrain: load greyscale height maps onto a 3D terrain, and allow for further height manipulation via sculpting
  • Flood: water simulation reacts with objects in a 3D environment, accumulates behind terrain/objects for flooding to occur, flows from high to low regions, and allows for user interactions such as adding/removing of water
  • Two-way coupling: water makes dynamic objects float while the dynamic objects cause ripples on the water after displacing it
  • Interactivity for the Web: all the above should run real-time in a web browser using HTML5 technologies

Main Libraries Used

  • WebRTC – JavaScript API for real-time communications in web browsers
  • three.js – JavaScript 3D library
  • skarf.js – Three.js framework for JavaScript augmented reality libraries
  • skulpt.js – Three.js GPU height field terrain sculpting library
  • skunami.js – Three.js GPU height field water libraries
  • Physijs – Three.js rigid body dynamics system

Demo

Interactive HTML5 Augmented Reality Flood Simulation

[ Live Demo ]

  • Tracking of webcam video stream
  • Using GUI markers system to control user settings with AR markers
  • Loading of models when associated markers are detected
  • Usage of main marker to define origin

I am a Senior Technical Director with strong interests in both tech and art. My life evolves round VFX, photography, software engineering, tools programming and generally anything that looks / sounds cool.
I have done a variety of CG programming, including fluid sims, muscles, soft/rigid bodies, raytracing etc. These knowledge complement the visual works that I do as a TD in VFX.
I was interviewed by The Straits Times in May 2014 for my VFX work in X-Men: Days of Future Past.
