Hi!

I've changed CcdPhysicsDemo\CcdPhysicsDemo.cpp, line 579 from
float speed = 40.f;
to
float speed = 120.f;
and see bullet-through-paper effect. Why?

Thanks.

There is an updated version that shows very basic CCD.
The method used in Extras\PhysicsInterface\CcdPhysics\CcdPhysicsEnvironment.cpp is very basic.
See the Win32 demo here:

Or get the latest sources from http://bullet.sourceforge.net

Cool demo!

P.S. I found out that "const int numObjects = 240;" needs huge amount of stack memory when LCP is turning off. /STACK linker option helps.

I still can't get get CCD. It goes through at 370 or so initial speed. I have got the bullet 2.67. Is there anything special I have to do when running the application to get results. note I have already tried pressing '1'.

Ok I saw previously posted example and yes it does work. is the appccdphysicsDemo broken?

btContinuousDynamicsWorld is currently not activated, we are working on this. The CcdDemo is using btDiscreteDynamicsWorld, hence the issue. There is a continuous collision detection query, but response is work-in-progress.

We will let you know once this has been sorted,

I saw in the todo-list that this is still there, is there some planning for when full CCD is possibly again? It is a wonderful feature, so I would like to experiment with it!
