Physics
There are many bundles related to physics, including
- A Physics (activity) which provides a physics engine and scene editor
- A Physics (collection) (with articles about physics in a few languages)
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, including Box2D, which is used in Physics (activity).
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)
|
See Physics (activity) (and Activities) for details of the Sugar physics scene editor being built using the open source Box2D physics library.
Current needs include:
- a format for scenes that can be shared across engines.
- a way to save/export(/import?) a scene from within the activity
Activities (current and planned) that would rely on this include
- the Physics activity
- a planned Incredible Machine variant, x2o
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
Physics curriculum materials
There is a very interesting on-line hogh school physics course here: http://online.cctt.org/
