Math and (Quasi) Physics in Action Script 3 – Verlet Structure

Verlet integration is a numerical method used to integrate Newton’s equations of motion. It is frequently used to calculate trajectories of particles in molecular dynamics simulations and video games. The verlet integrator offers greater stability than the much simpler Euler method, as well as other properties that are important in physical systems such as time-reversibility and area preserving properties.

A liquid-like effect based on quasi-metaball.

The next step is to dynamically put the photos on the map. I found googlemap API v3 is quite handy and could mock it up in a few hours.
The application can be run also on iPhone and Android phones and automatically locate your current place if the phone support the function.

Photomap

Many photos are taken right on the Bay Bridge, interesting.
Photomap – San Francisco!

In preparation for the next project, I’m playing around with geotag related APIs.
The first sample I made is a combination of Googlemap and Flickr that shows the photos taken around the place where you click.
It’s interesting to see that there is a considerable variation in numbers of photos taken by location.

In another experiment, I laid out the images from Flickr onto the maps according to their locations.
Again, the numbers of photos available totally depends on the location. So many pictures are overlapped and hidden around the popular places like Ginza, while there are many places with no pictures.
If much more images are placed on a bigger map, like on a A0 print, it will give a great overview of a city.
Clicking on a image shows it in full size (1350 x 1350px).
