Physics

There are many bundles related to physics, including

• A Physics (collection) (with articles about physics in a few languages)
• A Physics (activity) which provides a physics engine and scene editor

There was a physics meeting on July 10.

Physics simulations

See physics engines for a list of a few engines, and their current state of compatibility with stock Sugar builds on an XO.

mokurai is looking into other things that exist for upcoming discussions.

Brian and Daniel looked at various ports/wrappers of Box2D:

• http://box2dflash.sourceforge.net/ Actionscript 3 Box2D - I tried this on the XO with the latest joyride in gnash... it wouldn't load. Will somebody please try with Flash?
• http://jbox2d.org/ Java box2d... made by user:ewjordan No chance of working on the XO any time soon.
• http://box2d-js.sourceforge.net/index2.html Javascript Box2D - actually has the 5-ball pendulum you describe, in addition to a cool motorjoint-based ball-paddling/juggling device - I tested JS on the XO with the latest joyride -- it ran reasonably with two objects, unreasonably slow with three.

Physics (activity)

Physics sources in activities/physics .xo Bundle – Physics-0.1.xo Brian Jordan, Alex Levenson, Chris Hager

See Activities and Physics (activity) for details of the physics engine and scene editor being built.

Current needs include:

• a format for scenes that can be shared across engines.
• a way to save/export a scene from within the activity

Activities planned that would rely on this include

• a scene manipulator and an incredible machine variant.

Physics (other bundles)

There are physics collections in a few languages. There are also a number of unsugarized physics engines or simulators that have been tested on the XO, which could be made available
