The btGpuDynamicWorld class about bullet3 HOT 3 CLOSED

Yes, btGpuDynamicWorld still works at least under Windows (haven't tested Linux/OSX recently).

You need to checkout both the Bullet 3.x repository AND the Bullet 2.x repository in the same location, and then create the build system with premake:

Linux:
premake4_linux64 --bullet2gpu gmake
OSX:
premake4_linux64 --bullet2gpu xcode4
Windows:
premake4_linux64 --bullet2gpu vs2010

It should still be very easy to swap btDiscreteDynamicsWorld (or btCpuDynamicsWorld) with btGpuDynamicWorld .

I have compiled and executed the App_BasicGpuDemo on Ubuntu 12.10 64bit successfully.
Steps:

1. Checkout the bullet2 and bullet3 repository sequentially. Carefully, the bullet3 files must override the bullet2 files.
2. (naming error) Move all files in the demo3/BasicGpuDemo to Demo3/BasicGpuDemo
3. (compiling error) Modify Demos3/BasicGpuDemo/b3GpuDynamicsWorld.cpp

line 131 btQuaternion t_orn = (const b3Quaternion&)m_collisionObjects[i]->getWorldTransform().getRotation();
=============================Modified=================================
line 131 btQuaternion t_orn = m_collisionObjects[i]->getWorldTransform().getRotation();
line 132 b3Quaternion orn = (const b3Quaternion&)(t_orn);
4. (Makefile) type "make App_BasicGpuDemo" at /build/gmake directory, and the binary executable file is at the root directory of bullet3, not the /bin directory

thanks

from bullet3.

All the issues should be fixed now in latest revision.
Thanks for the report!
