A re-updated version of a previous experiment I made years ago to plot the tracks of storms. It now uses much more efficient technology to render everything and currently displays all 9,300+ storms and around 250,000 track points for storms from 1851 up to the present day.
2017-09-05: Updated with latest storms and now you can pass filter parameters in the URL. One use for this is to display everything or specific storms.. E.G. Hurricane Katrina, Hurricane Irma and Typhoon Tip
This WebGL experiment allows you to interactively compare the sizes of our sun, the planets and moons as well as (from February 2017) the sun and planets in the Trappist One system (albeit with a good measure of artistic license for the appearance). This new version now lets you compare multiple bodies with each other.
An interesting blog post from David Robinson (a data scientist at Stack Overflow) inspired me to revisit an old experiment I made called Flight Stream. I wanted to make it more generally useful for illustrating flow between sets of points on the earth and also make it support lots more points. David was kind enough to share the source data from his post with me and I used it to make the changes. As per the blog post, this visualization represents a days worth of global information exchange on Stack Overflow (data is anonymized).
An early iteration of something I have been working on for the Second Life viewer - support for exporting a 360 snapshot of any region and viewing it on the web. This version also supports exporting an equirectangular image with the right meta-data headers so it can be uploaded to sites like Facebook or Flickr and viewed correctly. More examples from the ever amazing Torley Linden can be found here and here.
An experiment that tries to illustrate how global temperatures on earth have changed between 1850 and 2016. Data via UK Met Office Hadley Centre for Climate Change. Inspired by the great work of Ed Hawkings, a climate scientist in the National Centre for Atmospheric Science (NCAS) at the University of Reading.
After playing with Street Cloud, French film maker William Laboury contacted me and asked if I could help with an app to extract the depth panos from Google Street View for a video he was working on. I was happy to help and leaning on some earlier work along with some code from others (see credits), I put together Pano Getter. Let me know what you think.
I've been quiet for a while because I've been working on a C++ based VR web and media browser experiment in my spare time. It renders any web content using the latest version of Chrome (v51) via CEF and any video using the latest version of VLC. Shaping up nicely but I don't have an Oculus CV1 headset so if anyone out there has a spare one or wants to help fund the project, please get in touch :) Nothing to show publicly yet but details soon.
Something I entered for the Christmas Experiment 2015 site but evidently, it wasn't high enough quality. I still like it though - Happy Holidays to everyone.
Three.js BufferGeometry is very fast but only one draw call so it's not possible to hide or show parts of it easily. This example illustrates a way to do that by setting an attribute on each vertex and culling them out as necessary in a shader. Feedback appreciated
Experiment to compare the relative sizes of planets in our solar system, including of course the new darling, Pluto. Updated to support the Sun and the Moon.
The THREE.Geometry classes are easy to use but slow and the THREE.BufferGeometry class is fast but hard to use. This experiment tries to get the best of both worlds by creating geometry the easy way and transforming it into the fast way. Works well on mobile too. Updated to support multiple geometry types
My entry for the 2015 NASA Space Apps Challenge. Provides a way to view and explore the almost 1.8 million photos taken from the International Space Station over 15 years and 44 missions. Updated to include all of Mission 43's 173,544 photos and the 9,388 current ones from Mission 44
Experiment to visualize all of the worlds flights. Not displayed in real time or on a correct schedule although that might be nice for version 2.
Second attempt at extruded earth visualization I'm working on for a bigger project.
Experiment to let you add manipulator UI (via dat.GUI) to modify objects in a three.js scene on any page via a bookmarklet.
The next iteration of Street Cloud. This version generates multiple views based on a starting location. Lots left to do but makes quite beautiful images. See Help dialog for more details.
Generate a template three.js application using interactive controls and use it as the starting point for your next masterpiece. Select options, features and code then save it off as a zip file. Updated (2014-06-27): Now you can send it to a JS Fiddle and include helper geometry objects.
An experiment to render Google Street View ® scenes as 3D point clouds using the LiDAR data captured along with the regular panorama images. A rudimentary navigation system allows you to move between connected locations. Updated (2014-07-09) Change in internals of StreetView API broke it for a while :(:
Interactive map of hurricanes, typhoons, cyclones and tropical storm tracks from 1848 to 2013 including Super Typhoon Haiyan/Yolanda.
Simple Python script to generate a template Three.js app that you can use as a starting point for your next masterpiece.
Experimenting with data visualization by extruding world countries based on a metric.
Lat/long connected spline based arcs over planet Earth with logo, tweening and UI.
Experimenting by mixing up bits of Pixi.js demos. Click to jump.
Manipulate a globe and go to or pick, lat/long coordinates.
Testing buffer geometry with 100,000 lines - next, make it move with a shader.
Testing sphere and ray intersection code.
More complex intersection test against a 3D model
Animated shader on spline.
Red planet with extruded circle splines plus animated shader and collinear icons.
I wanted to subdivide country outlines into triangles and thought Delaunay triangulation was the right answer but it's not.
Experimental canvas based UI widget with lovely people at Concept Arts.
Testing how to render collinear squares on a sphere.
Test loading model from CTM file and apply environment map.
Load a model of a duck from a Collada file.
Discover how many minutes speeding really buys you.
My day job at Linden Lab since 2004
Open source project from 2005 that renders web content to a texture.
Open source project from 2006 that displays a 3D web browser.
