Project: Building rigid body simulations using Blender's Bullet game engine

[iluvblender]

Hello folks.

Couple of projects to demonstrate setting up of rigid body simulations using Blender's Bullet game engine.

You can download the blend file at the project pages linked to the images.

Setting up very basic rigid body simulations using ball and hinge constraints

Setting up a multiple pendulum effect using ball and hinge constraints

Following is another example of setting up a compound rigid body object. Its self explanatory (Click to enlarge), and you can download the ***blend file*** (http://uploader.polorix.net//files/292/Blender/GameEngine/CompoundObject.blend)
