Real-Time Physics Simulation Forum

Although no SIMD yet (hopefully soon), Bullet 2.40 has the following features:

Preliminary new features:
- test for optional double precision
add a #DEFINE BT_USE_DOUBLE_PRECISION 1 at the top of LinearMath/btScalar.h, or add this define in the build system/projectfiles.
- test for motors, see hinge and ConstraintDemo
- test for make
./autogen.sh, configure will generate Makefile AND Jamfile
- constraint solver mixes contact and non-contact constraints inside the iteration loop. This used to be 2 separate loops. Mixing will lead to better behaviour during collisions that involve constraints like ball-socket, hinge or generic 6dof.

Thanks for the contributions, gunner10 and Joerg.

I tried compiling this package but it fails.
The rest doesn't work neither ( ./configure fails and there's no jam config file ).

autoconf (GNU Autoconf) 2.60

Deleting lines 70 up to 82 in configure.ac solves this problem but is a rather ugly hack.

If autotools/configure doesn't work, please use CMake instead, or the provided Microsoft visual studio projectfiles.

In the meanwhile, we are working on fixing autogen.sh/configure.ac so it creates both make/Makefile and jam/Jamfile.

Any help in this area is welcome!
Thanks for the feedback,

OK, reverted to old jam build system, without the changed to support 'make', until things work properly. See Bullet 2.41.tgz.

Thanks,
Erwin
