The new version of the Particle Physics Simulator for Android is now out in the Market. The main new feature is the addition of background images to the simulations. Here’s how they work:

First, go to Settings and scroll down to the Background Image entry. Then, click on it and select the image you desire from your gallery/external storage. And yup, that’s all! The images are conveniently cropped and scaled so that OpenGL ES can handle them. OpenGL ES only accepts square textures whose side length is a power of two, so what the app does is basically calculate the largest square-of-two-sided area that fits in the selected image and then crops it.

I just submitted a new version (v2.5.5) of the Particle Physics Simulator to the Android Market, so you should be receiving it shortly in your devices. This is a bugfix version:

  • Fixed bug that prevented simulations in merger collisions mode from working properly. Thanks to Neil for reporting.
  • Some minor performance improvements have been added that should make the simulator run more smoothly.
