A small (win32, VC 7.1) demo using Irrlicht. Hit 1-6 to add objects, shoot to remove them.
This is a basic framework that demonstrates loading meshes and sharing of various different collision shapes. Also a simple 'hello world' demo to get Irrlicht users started with Bullet.

That looks like a really nice demo already.

Could you add the option to display debug settings using Bullet btIDebugDrawer interface? And wireframe rendering?

Also it would be good to see which percentage/cpu cycles go to graphics, versus physics.

Thanks,

OK, I'll add some debug display options to the demo very soon, and do some simple profiling to measure the graphics vs. physics CPU usage.

I've added a window to display some stats, including the btProfiler info. The demo now has wireframe display, aabbs, deactivation of obects (they go a bit darker) and shows Bullet's percentage CPU usage.
I implemented the btIDebugDraw interface (obviously), but I didn't use drawLine (since it is easier to let Irrlicht do AABBs) or drawContactPoint.
I haven't implemented these debug draw modes:
DBG_DrawFeaturesText
DBG_DrawContactPoints
DBG_EnableSatComparison
DBG_DisableBulletLCP
DBG_EnableCCD
But I could always add these later on, if they would be useful to anyone.

This version uses the multi-threaded runtime library to avoid linker errors. The original demo had a huge poly count for the spheres, they have been cut down, and now you can also hide much of the geometry. Instructions on-screen.

Hi. I want to use Bullet with Irrlicht in Dev-CPP but didn`t found any tutorial which describes how to integrate Bullet with Dev-CPP. Is this possible? As i know Dev-CPP need files with specific extension (.a if i remember correctly) but i don`t know where or how to get it.

Sorry for my poor english..

That´s a great demo. The combination of bullet and irrlicht is perfect.
Did you make already a second demo ?

I hope you make more stuff like this because we plan to include bullet in our 3D world.

Demo application quits itself always when keys 1-6 are pressed. So can´t see any physics. What causes that?

Better, simpler, more up to date demo here:
