This keva planks (kapla / keva plank) building collapse animation has been realized with blender 2.64, Bullet Physics Engine and Cycles Render Engine.

An other time, I should try to make an angry birds or a minecraft demolition / destruction with blender game engine and bullet physics ...

If you want to learn blender game engine and bullet physics, you can have a look to the very good Phymec's tutorials here : [ Ссылка ]

When I saw Phymec's keva planks demolitions, I decided to make my own once, my favorites Phymec's videos are :
"Over 32000 planks ;-) Blender / Bullet Physics / SmallLuxGPU OpenCL" [ Ссылка ]
"KEVA planks round tower build and destroy using Bullet Physics Engine" [ Ссылка ]
"3000 KEVA planks in slow motion (Updated) - Bullet Physics" [ Ссылка ]
"Over 5000 KEVA planks building - Bullet Physics" - A little KEVA planks stress test with Bullet Physics engine. Total 5278 rigid bodies. Pretty solid. Same destruction from three different POVs.

Fun Physics news: Version 2.80 of Bullet Physics library (for developers) has just been released and it includes (amongst other new features) a preview of the GPU OpenCL accelerated rigid body pipeline which should be finalised for the upcoming version 3.0. Erwin has put up on his YouTube channel some real-time (!) technical tests with tens and even hundreds of thousands of rigid bodies. Open source software:
