8d26ff356d allow links without collision shapes in btMultiBody URDF importer 2015-09-25 17:00:44 -07:00
=
5e4badc099 make PhysicsClient an interface class, and move shared memory implementation 
of physics client into PhysicsClientSharedMemory class/file.
This will allow implementation of UDP and other transport protocols to a physics server.

e05825f639 improvements to the shared memory physics API: 
support picking in C API etc.

23bdd0ed36 more work on physics client c-api over shared memory 2015-09-17 09:37:44 -07:00
=
003a42478b another step closer to useable shared memory C API 
(force/torque sensor needs new API)
in a nutshell, users of shared memory physics API should not
directly poke into shared memory, not fill 'SharedMemorCommand'
nor read SharedMemoryStatus directly. The C-API declares 'handles' for those,
to avoid it from happening.

2257ec05ad don't compensate for COLLADA up axis in collision element for now 
(todo: let user override COLLADA up axis, some URDF files are inconsistent)

Detach posix shared memory correctly

4cbd86a058 Detach posix shared memory correctly 
* shmget() fails after shmctl() is called with IPC_RMID. This patch
removes shmget() in releaseSharedMemory so that a client can detach
a shared memory correctly after a server removed it.
* A server should also detach a shared memory.

081a40d254 initial implementation to send debug lines from physics server to client, 
need to add streaming because memory is too small to store all lines
initial test of PD control in physics server, need to switch to PD control for motor constraint, instead of using external forces.
